Control System

The standard control system for the A22LS is the straight stick.  However, the Y stick or Yoke are also available.  (More info below)

Airbox Carb Heat

The Airbox Carb Heat is standard with ULS.  While the Rotax is not prone to carb ice, it is possible in the right conditions. Another advantage to this feature is that it uses an air scoop on the cowling for cold air intake which gives a slight performance increase. If you are familiar with carb heat on traditional aircraft engines, you are probably aware that the carb heat bypasses the air filter and sends unfiltered air to the intake. This is not the case in the Aeroprakt. The air is filtered regardless of whether the carb heat is on or not. Therefore you can run carb heat on the ground to help the engine warm up faster. If you are selecting the iS engine, carb heat is unnecessary and is not an option.

Wing Strut Fairings

Wing strut fairings are standard on all Aeroprakt models. It not only cleans up the aerodynamics, but it improves the appearance as well.

Artex ELT

This is a requirement for USA aircraft. This is the new style 406 frequency ELT. It has a GPS location function and is registered to the aircraft and to the owner. It must be registered when you take possession of the aircraft and every two years after that. The battery has a 6-year replacement interval. The new ELT’s are much better than the old 121.5 models. Not only is there someone actually monitoring them, but they report the tail number and location upon activation and continue to do so until the battery dies or it is deactivated. They are self-contained and can be removed from the aircraft and carried if you need to leave the scene; search and rescue would therefore be tracking you and not the wreckage.

Parking Brake

The parking brake is a standard feature for safety. When starting the Rotax engine, it can easily rev up if the throttle is not set to idle and it will lurch forward if the brake is not on. It would be a serious safety concern to not have a parking brake.

Cabin Heat

Cabin heat is a standard feature. Cabin heat on a Rotax is supplied by air coming through the radiator rather than the exhaust, eliminating and danger of CO.

Autopilot Servo Mounting Tabs

The autopilot servo tabs are a standard feature, necessary for the autopilot installation.

Spare Switches & Fuses

As a standard feature, two spare switches and fuse slots are included, if space permits, for future upgrades.

Other Standard Features

Mechanical Trim Tab, Engine Electric System Installation, Custom Instrument Panel Layout, Cradles for Transportation, Fabric Covering and Priming, Standard Glazing on Fuselage, Single Color Painting

Paint & Fuselage

Paint

Aeroprakt can use nearly any RAL color. The factory is reluctant to shoot metallic colors due to material availability as well as the increased time it takes in the manufacturing process. If time permits, for an extra fee, they usually will do metallic, so don’t hesitate to ask.  It is possible to paint a two color scheme, however, the design is very limited. It is possible for example, to mask a line down the fuselage or paint major sections such as wings or control surfaces a second color. Generally, the best option is to pick the base color you want then add accent color with vinyl. You can also take your aircraft to a paint shop and have an accent color(s) painted on to it.

Fuselage Aluminum Skin

This is simple a preference on how you would like your aircraft to look. Most people prefer the look of the aluminum skin, but there is no reason beyond appearance to go one way or the other.

Controls

Controls

Center (straight) stick, Y stick or Yoke. The A22 is available in either center stick or yoke configuration. In the stick configuration you can choose between a straight stick or a Y stick. Generally the Y stick is preferred for training operations, but some people find it more comfortable as well. The center stick has the brake handle on the stick, and the Y stick has brakes on both handles. When deciding between yoke or stick, there are a few considerations to think about. One would be throttle placement. In the yoke model, the throttle is in the center console with the brake handle integrated with the throttle. This is convenient and comfortable.  One negative aspect would be if the airplane is used for flight training, it can be more difficult to get to the throttle fast if a student has their hand on it. With the stick model there is an independent throttle on both sides between the seat and the door. This works well for training, but one possible negative is that it is somewhat in the way when entering and exiting the aircraft. Another consideration between stick and yoke would be brakes. The stick model has considerably more leverage on the brake lever and brakes more effectively with less pressure. With the yoke model it takes considerable pressure to get effective braking. With the A22, I have found that the control pressure of the yoke version is noticeably heavier on the ailerons, and a lateral weight imbalance will create a noticeable heavy wing feeling. In the stick model, the ailerons are very light and responsive and the lateral weight imbalance is generally unnoticeable. (The A32 does not seem to have this negative attribute with yoke control). One other consideration I have found between the yoke and stick is that on a cross country flight where the autopilot is being utilized, it is pretty nice to not have a yoke in your lap. The extra space adds to the comfort when you want to eat a meal or if your passenger is working on an iPad or laptop.  Another consideration with the stick is that you will need to reach across to engage the flaps or work avionics.  With a yoke configuration you would naturally fly with your left hand and have your right hand available for working the flaps or avionics.  With some time in the airplane this is a very minor factor.  Also consider that on the A22 the yoke option is a significant cost increase.  Sometimes people are afraid of switching from what they are used to in previous aircraft, but it really is a non event.  You will become accustomed to either configuration quickly.

Handicap Control Option – Hand Only

This option is available only on a yoke control model. It interconnects the rudder pedals with the extended throttle lever. This allows full control of the aircraft with hands only; no pedal movement is necessary. In just a few minutes, the linkage can be repositioned to make the controls normal again. When the link is in the interconnected position, the rudder pedals still continue to work normally, so it’s easy to fly in either configuration.

Stick Control Lock

Definitely get this option if you have stick controls. If you ever tie down your airplane outside, or even park to refuel or eat in windy conditions, the wind can quickly damage the airframe if the controls are not locked. If you are opting for a yoke control system, it will have a lock pin already and this option will not be relevant.

Electrical Trim Tab

The standard trim on the A22 is a lever in the center console. It works very well. The electric trim can be added and the control can either be a switch in the panel, or a thumb switch on the stick grip, or in the case of the Y stick, on both sticks. Generally this option is used for flight training where the student and the instructor both have easy access to the trim and the indicator displays it’s position.  Compared to the standard mechanical trim, the electric trim is slower.  In the A22 there is a considerable pitch effect when the flaps are deployed which creates a need for a significant trim adjustment.  A quick swipe on the mechanical trim and it’s set.  With the electric trim it takes several seconds to cycle to the correct position.

Dual Electric Trim for Y Stick

If you have Y stick controls and electric trim, and you would like a trim switch on both handles, select this option.  This would be mostly used in a flight training environment.

Engines

Engines

There are two engine options available: The Rotax ULS and iS. There are good reasons for both the ULS and the iS engines. Some people like the up front cost savings of the ULS and the simplicity of maintaining it in the field. The ULS is also lighter than the iS by about 15 lbs.  (That weight penalty is saved in fuel in about 2.5 hours.) The Bing 64 carbs on the ULS do compensate for altitude to a point, but they are limited. The fuel injection tunes the engine to optimal performance and efficiency at all altitudes. The ULS and iS require a minimum octane of 91 by the USA standard (AKI).

The Rotax iS offers several amazing advantages. The most talked about is the fuel savings. Rotax claims a 30% increase in fuel economy, and real world experience in the Aeroprakt confirms that.   Another advantage to the iS is extra charging capacity. The iS has nearly double charging capacity of the ULS.

One question that is often posed about the iS engine is the reliability of the electronics. The Rotax iS system is completely redundant. There are two completely independent “lanes.” Each lane has a completely independent fuel and ignition system. Every sensor, fuel pump, fuel injector, computer, charging system, voltage regulator, ignition coil, etc. is redundant. If anything in one lane fails, it continues to run on the other lane. Once started, the iS does not use battery power, rather it runs directly from it’s internal charging system. If one charging system fails, it will run on the other charging system. If both charging systems fail, it can run on battery power with the flip of a switch. The iS is a very well designed and reliable system.

The iS engine requires far less scheduled maintenance, reducing maintenance cost and downtime.  However, the iS does require a technician that is Rotax trained and equipped to troubleshoot any problems that may arise. In some areas of the country, these technicians are few and far between.

Oil Thermostat

The oil thermostat will bypass the oil cooler until the oil temp is warm enough.  This allows for quicker warmups and helps keep the oil at a stable operating temperature in flight.  It is definitely recommended in colder climates.

Propellers

Props

The three propeller options that we currently recommend for the A22LS are the Kiev, E-Props  and DUC.

The Kiev propeller is the lowest cost and performs well overall.  The Kiev has the lowest service life of all of the props with blade replacement being necessary at 6 years.   When considering the overall cost of operation over the life of the aircraft, the Kiev will be the most expensive. 

The E-Props propeller has a very narrow blade and you wonder if it could actually grab enough air, but it performs exceptionally well. While you do give up a bit of static thrust with the 3-blade E-Props, once rolling down the runway you can feel it really start to grab.  There is a slight increase in takeoff roll and reduction in climb with a 3-blade E-props on the A22, however, cruise is improved slightly.  On the A22, a 4-blade E-Props produces a significant increase in thrust and climb and yet still improves cruise speed.  Another significant advantage to the E-Props is the balance and extremely smooth and quiet operation.  This is even more noticeable with the 4-blade option.  The E-Props also has the advantage of being much lighter.  The 3-blade E-Props, complete with spinner and mounting bolts, is less than 6 lbs.!  The Kiev prop is about 12 lbs.  Not only does that reduce the empty weight of the aircraft and increase useful load, but less rotating mass reduces the load and wear on the engine and gearbox.  E-Props has the best service life at 4,000 hours and unlimited calendar time.  At TBO the E-Props simply requires an inspection by the manufacturer and can be put back in service.  It can be run indefinitely with 4,000-hour inspections.  E-Props now has props in service with in excess of 30,000 hours of operation!  The E-Props comes with a bare carbon fiber spinner.  Overall, I think the 4-blade E-props is the best match for the A22 for performance, durability and cost of operation.

The DUC Flash propeller is now a factory option on the A22.  We have not tested the DUC Flash on the A22 yet, so I cannot say for sure how it will compare.  Many people like the appearance of the DUC better.   We can provide a bare carbon fiber spinner, or it can be painted to match.  The decals on the blades can be ordered in several different colors.  There are two disadvantages to the DUC.  One is weight.  The DUC weighs in at 13 lbs. with spinner, spacer and bolts.  The second is cost.  The DUC is significantly more expensive than the E-Props.  The TBO on the DUC is 2,000 hours or 5 years, but if it passes inspection may continue to be used.  Inspection is done by the the distributor in the USA and is quick and inexpensive.  The service life of the DUC is indefinite if inspections are completed.

Fuel Tanks

Fuel Tanks

You will need to select between 24 and 30 gallon total capacity fuel tanks. Nearly everyone opts for the 30 gallon tanks. There is no weight penalty. The 30 gallon tanks do have a bubble look to them where the 24 gallon tanks fit in the contour of the wing. Realistically, 24 gallons will probably provide longer range than most people are capable of.  However, there are some reasons to consider the larger tanks.  When you land at your destination and the fuel pump in inoperative, that extra fuel might allow you to get to another airport safely where the smaller tanks would leave you stranded.  Another scenario to consider is that the Rotax prefers unleaded fuel, and those stations tend to be fewer and farther apart.  Larger tanks may allow you to avoid leaded fuel in many cases.

Landing Gear

Wheels

There are three options for tires: 15-6×6, 6×6, and 8×6. A 15-6×6 wheel is the standard wheel and works well on good sod or pavement. This is the only size that will fit in wheel pants.  The standard 6×6 is taller than the 15-6×6 and is an excellent option for flight training, rough sod and mild off airport operations.  The standard 6×6 Airtrac tire is also considerably less expensive to replace than the 15-6×6.  The third option is an 8×6 Carlisle Turf Glide. They are inexpensive and work well, although they are not a real precise tire and require balancing.  If you would like a larger tire, there are wider 8×6 tires in the aviation market, but they get pretty expensive and are also fairly heavy. When selecting the tire size, keep in mind that the nose fork and strut are matched to the tire size. Changing the nose wheel to a different size would require changing the fork and strut as well.

Wheel Pants

Also referred to as wheel spats, wheel pants add a very classy look. They also keep the airframe cleaner and reduce drag. The effect on speed is about 3-5 mph at best. While not a drastic increase, every little bit helps!

Mud Guards

Mud guards are designed to protect the airframe from debris and mud kicked up by the tires. While they don’t stop 100% of it, they do greatly help. They are very light weight and have no affect on drag. If you are not running wheel pants, I would recommend the mud guards. The mud guards are matched to the tire size, so if you change the tire size you will need to change the mud guards as well.

Titan Skis

Snow skis are available for the A22LS.

Fuselage Seaplane Brackets

Float installation brackets can be installed at the factory for future float installation. Currently, Full Lotus are the only floats approved for SLSA aircraft and they are apparently out of production. If the aircraft is ELSA, there are a few options available for floats. If you are considering putting floats on in the future, it is far less expensive to have the attach points installed at the factory than to have them installed later.

Fuselage Lifting Brackets

If floats are installed, the fuselage lifting brackets allow for a convenient and safe lifting point for switching from floats to gear.

Cabin

Non-Standard Dashboard

This option provides additional legroom for tall people. It’s a good idea to add that even if you do not need it. If you decide to sell your aircraft someday, this feature may be a big asset to the next owner and the cost is very minimal. There is no disadvantage to this option beyond the added cost.

Warmth Keeping Partition

This option is a partition that separates the cockpit from the baggage compartment and tail cone with the purpose of keeping heat in the cockpit.  It does significantly improve the cockpit temperature in the winter.  The disadvantage is that it restricts access to the baggage compartment in flight.  You do have access, but it’s limited.  It can, however, be easily removed for summer operations.  If you routinely fly in very cold weather, the A32 does have a better heater.  That might be enough of a factor to upgrade in some cases.

Headliner

The headliner in the A22 is an optional plastic panel overhead and around the storage compartments. While it does create a more finished look on the interior, the A22 looks perfectly natural without it. The storage compartments are metal and built into the airframe, so they will be there with or without the headliner.

Photo Windows

These slider windows allow for unobstructed photography and are very nice for that purpose. However, it should be noted that they are a bit drafty in cold weather and they leak water when flying in rain. They also obstruct the view somewhat when they are closed compared to a door without them. If you live in a very hot climate, they can also be used for ventilation.  Alternatively, you can add an additional turn vent on each side to increase air flow. Photo windows can be installed on one side or both.

Fabric Baggage Bin

The fabric baggage bin can be selected instead of the baggage door.  When selecting the baggage door, it will automatically come with a solid, permanent baggage compartment.  The fabric baggage bin is lightweight and easily replaceable, however, it will not hold as much volume as the solid compartment.   Access to small items in the fabric bin is convenient, though loading larger items into it can be more difficult as you reach over the seats and around the vertical aileron pushrods.  If you plan to carry a significant amount of baggage, the baggage door option would be recommended.

Baggage Door

When selecting the baggage door, a solid floor and back baggage compartment is installed along with the exterior door to access it.  This option allows for more baggage space and easier access than the fabric baggage bin.  It is amazing how much can be packed into this baggage compartment.  This option is far more popular than the baggage bin.

Cabin Cover for Storage

If you plan to have the airplane outside very much, this cabin cover is very nice to protect the windshield and interior from sun and debris. It folds up into a tight little bag and goes with the airplane easily.

Defroster Fans

This option should always be selected. They are very inexpensive and add very little weight. These defroster fans pull heat up from below and blow on the inside of the windshield to melt frost or help keep it from fogging. Another advantage is that these fans help circulate heat in the winter and enhance comfort.

Key Locks for Doors

These key locks are a popular option and help to keep honest people honest. It would not be very difficult for a person to break their way into an A22 if they really wanted to steal something. However, the locks will at least keep people from opening your door at a fly-in and “looking” at things. They will also keep kids from tampering with the cockpit and such. In a public area, it is unlikely that someone would force entry into a locked airplane, but if it were unlocked, things could be taken without anyone’s notice.  Don’t forget to include a lock on the baggage door if you have selected that option.

Lights

Landing Light in Cowling

Even as a sport pilot in day VFR only, having at least one landing light greatly improves your visibility to traffic on the ground when you are on final. If you plan to do night flying, wing landing lights are also recommended.  This will also allow you to use the cowl light for taxi so you don’t blind people with the wing lights.

Wing Landing Lights

If you would like wing landing lights, you can choose one or two. If you choose two, you also have the option of choosing the wigwag circuit that will alternate one side then the other about every second. This greatly improves your visibility to other traffic. If you fly in a busy airport environment, this will be a huge asset. When the wing lights are on solid and the cowl landing light is one, it really lights up the terrain at night. In pitch black you can start to make out objects on the ground at 200’.

WIG-WAG Landing Light Circuit

(See “Wing Landing Lights” above.) This option adds a switch and controller that when activated will make the wing landing lights flash in an alternating pattern to improve visibility to other traffic. It also uses half the electrical power as having them on solid. (Having all the landing lights on solid at low rpm may cause a discharge with the ULS engine.)

Wingtip Nav/Strobe Lights

Wing tip lights are recommended for visibility both night and day. In the USA they are required to fly past sunset, into civil twilight.  They greatly increase your visibility to other traffic, even in daylight. These lights are actually made by Aeroprakt, and we do stock replacements should you ever need one.

Backlit Panel for Night Flying

This option is for light bezels on any steam gauges you are having installed. If your instruments are all digital, this would not apply. For simplicity, the price covers all the instruments regardless of how many instruments you are having lighted.

Red Overhead Instrument Panel Light

This light is installed in the ceiling of the cabin to shine on the panel. While generally the glass panel and instruments are lit, this is very nice to be able to see the switches and such. If you do not fly at night at all, you may not have a use for it, but if you do plan to fly at night, it’s well worth it.

Electrical

Dual USB Charge Port

These charge ports can be installed to provide power to phones, iPads and other devices. The current production aircraft now use a port that has one USB-A and one USB-C port in each unit. The total charge capacity is 65 watt, so it will charge a large iPad even while using the device. You can select as many of these charge ports as you would like on the price sheet; simply use a number in the column rather than an X. Popular locations are in the instrument panel, on the side of the panel, or under the seat facing forward. Under the seat facing forward works well for an iPad on your lap.

12V Power Outlet

This is a port that we used to call a cigarette lighter.  A 12V outlet can be used with an adapter to power just about anything.  However, now that we have both USB-A and USB-C in the normal charge ports, these are becoming obsolete.  Even if a new style charge port comes along someday, these units are inexpensive and very easy to replace, so they could be easily upgraded.

Battery Main Switch

This is a switch located under the pilot seat that disconnects the battery from the system completely. It is very handy for long-term storage as well as for maintenance. It can also be a safety feature if there was ever an electrical short in flight.  This is a recommended option.

EarthX ETX900 Battery

EarthX manufactures lightweight lithium iron phosphate (LiFe) batteries for the aviation industry. Although these batteries had a reputation early on as a fire hazard, a lot of that was a result of a misunderstanding of the different lithium chemistries. Lithium polymer is the more volatile chemistry. EarthX has developed a circuitry that will protect the battery from over charging and overloading making a thermal runaway nearly impossible. EarthX has been approved in many certified aircraft. The advantages of the EarthX battery are better cranking power, longer life and especially weight savings. We offer the ETX900 battery which is significantly more powerful than the minimum recommended size, yet it saves 9 lbs. compared to the lead acid standard battery.

Avionics

Garmin G3X VFR Package

Garmin G3X Panel

The Garmin G3X panel is the main hub of this system. It handles all of the flight data, engine monitoring and display of information from the related components. It is a standalone system and capable of VFR navigation. The G3X has it’s own navigation database, displays all of the airport information, ADSB weather and traffic, approach plates, VFR and IFR charts, and much more. It has Bluetooth connectivity and will send and receive flight plans from an iPad or phone using ForeFlight or Garmin Pilot. The G3X has the capability to display satellite weather if equipped with an XM receiver. The Garmin suite is a very powerful and capable system.

GTR 20 Remote COM Radio

The GTR 20 is a remote COM radio that serves as the primary COM in the VFR package or Com 2 in the IFR package. It is controlled through the G3X display.

GT45R Transponder

Also behind the scenes is the GT45R transponder with ADSB in/out. This transponder is remote and is controlled through the G3X. It provides not only the transponder but also provides ADSB traffic and weather data which can also be supplied to your iPad over the Bluetooth link to the G3X.

AP507 Autopilot System

The AP507 autopilot system is a state-of-the-art autopilot that does everything you could expect of an autopilot, and it is easy to use. It will fly a heading, the nav course or a full approach to minimums. This autopilot system can capture a glideslope or glidepath and will fly the missed approach when commanded. It will climb or descend at a set vertical speed to a preset altitude and level off. It is essential to the single pilot IFR environment.

Garmin Options

Garmin G3X Dual 7” Displays Upgrade

This option uses dual 7” displays in place of the single 10.6.” These displays can be installed in the portrait or landscape orientation. Some people like this dual display option as it provides a backup in case the panel fails, although that is more of an IFR consideration. This option in a VFR installation is simply a personal preference for panel layout and information display layout.

Garmin G5 Flight Display

The Garmin G5 is a mini EFIS that fits in a standard 3-1/8 instrument hole. It can be used as a primary flight display if a full glass panel is not installed, or it can be used as a backup to a glass panel system. The G5 has an internal ADHARS sensor and a backup battery that should run for about 45 minutes in the event of a loss of electrical power. The ADAHRS sensor in the G5 can supply flight data to the G3X in the event of a failure of the main ADAHRS sensor. The G5 can also be configured to operate as an HSI. Two G5’s may be installed if desired.

GDL 52 Satellite Receiver

The GDL 52 is a Sirius XM satellite receiver that provides weather data to the G3X via a wired connection as well as to mobile devices over Bluetooth. As a side benefit, it provides an additional source of GPS position and attitude data to mobile devices. The benefit to satellite weather is a much greater resolution in radar images, faster refresh rate and the ability to pull up METAR data from distant airports. With satellite data in the lower 48, there are essentially no dead spots in reception area which is a concern with ADSB data. (XM coverage in Alaska is limited) The GDL 52 also provides Sirius XM radio in flight for music and entertainment. This unit does require a Sirius XM subscription to function.

Dynon HDX Touch VFR Package

Dynon HDX Touch System

This system is by far the most popular way to spec an A22. The Dynon systems have proven to be very user friendly and robust. This system includes not only the glass panel with ADAHRS sensor, compass sensor, engine monitor module, GPS module, AOA pitot tube system, but also the COM radio and intercom with control heads, the transponder with ADSB in and out, Wi-Fi to connect to your iPad or other device, and the autopilot. The price is for this to be fully installed and configured.

The HDX has a touch screen as well as hard buttons. It is very intuitive and functions well in flight and turbulence. The autopilot works exceptionally well and can fly a heading, track, or full flight plan with vertical guidance. You can even design a flight plan on your phone or iPad on ForeFlight and easily upload it to the Dynon by Wi-Fi and have the autopilot fly it. This system has simply amazing capabilities for a very reasonable price. If you design a steam gauge panel to save money, you will probably find that you are not saving very much, if any. Not having a glass panel system will also significantly reduce the resale value. The Dynon system is highly recommended.

Dynon SV-COM-245

This panel is installed to control the remote COM radio.  The upper knob is the volume and squelch.  The inner and outer lower knobs control the frequency and pushing the know swaps active and standby.   This radio has the capability of dual monitoring so that it can listen to both the active and standby frequencies simultaneously.  If you are in the “Info” screen for an airport on the HDX you can push the “Tune Com” button and it sends all the frequencies to the radio panel.  Then you can switch between tower, ground, ATIS, or approach at the push of a button.  The COM panel can be installed either vertical or horizontal to accommodate your desired panel layout.

Dynon SV-INTERCOM-2S

The intercom panel allows for easy access to adjust the volume and squelch of the intercom.  The Dynon intercom works exceptionally well.  This panel makes it very convenient to lower the squelch for talking on the ground at idle or to raise it for the increased noise in climb out.  The intercom pairs very well to LightSpeed headsets.

Dynon SV-COM-760

The SV-COM-760 is the COM radio that is mounted behind the panel and controlled through the HDX Touch display, or the SV-COM-425 control panel.

Dynon SV-XPDR-262

This is the transponder that is mounted behind the panel and controlled through the HDX Touch display.  ADSB in and out are also integrated into this transponder.

Dynon Options

Dynon HDX Touch 12” Display

Select this option to upgrade the 10” HDX Touch display to the 12” version.

Dynon SV-KNOB

This is a small panel that gives you hard knobs for Baro, Altitude bug and Heading bug functions. It is not necessary, but it is convenient if you fly cross country very much. You can do all the same functions in the HDX panel, but it takes a few more buttons to push.  These can be installed in the vertical or horizontal orientation.

Dynon SV-AP Panel

This is a small panel that gives you hard buttons for the autopilot functions. You can do nearly all of these functions in the panel with one exception. The AP panel has a straight and level button. Pushing this button will engage the autopilot in straight and level, holding altitude. This is a very handy feature. If you fly VFR into IMC inadvertently or suddenly have a medical issue, this could be a life saving device. Once in straight and level mode, you can set the heading bug, for example, and then hit the heading button and it will follow the heading bug. You could set the heading bug 180 degrees from your course and hit the heading button and it will turn around and fly you back out of IMC. You may also want to hit that button to simply write down what ATC is saying or change the squawk code, etc.

If you do not have the SV-AP panel, you can set the HDX to beginner mode for the autopilot and it will give you a straight and level button, but it takes away most of the autopilot functions, so that is undesirable.

These can be installed in the vertical or horizontal orientation.

Dynon Second Com Radio

Select this option to have a second Com Radio installed.  The Com 2 would be controlled through the HDX Touch screen.  The primary Com does have the ability to monitor two frequencies simultaneously.  Typically in a VFR scenario that ability makes a second Com unnecessary, but it is available.

Avionics Options

Red Fuel Flow Cube

This is the sensor that tells you fuel flow rate. If you are getting a Dynon system with a ULS engine, you will want to select this. If you are getting an iS engine, this will not be necessary as the engine supplies that data. If you do not have a glass panel or other instrument that reads fuel flow, this option will not be used.

Trig TY91 COM Radio

This is an excellent radio. The radio used in the Dynon HDX system is also made by Trig. The radio is included with the Dynon or Garmin systems, so it is not needed if you selected one of those. This would be used if you are building a steam gauge panel.

Trig T22 Mode “S” Transponder

Trig also makes the transponder that Dynon uses in the HDX package, so this is a very good quality unit. The transponder does not have ADSB unless it is connected with a compliant WAAS GPS source. For ADSB in/out, it would make the most sense to use the Uavionics ADSB option. When selecting a Dynon or Garmin system, the transponder is included and this option would not be selected.

Uavionix AV30

This all-in-one instrument is a valuable backup for a glass panel system or an excellent primary instrument for a steam gauge panel. It gives you nearly all the flight data of the glass panel. With all of these capabilities at such a reasonable price, the AV30 is a great value. Recently, the manufacturer made a change in the AV30 so that it no longer has an internal magnetometer.  The AV30 option now  includes the external magnetometer as well as the AV-Link  that allows it to connect to an ADSB source to display traffic or to a computer to upgrade the firmware.

Uavionics Echo ADSB In/Out Module

The Uavionics Echo is an ADSB only unit that supplies both ADSB in and out. This unit combined with the Trig T22 transponder would comply with FAA regs for operation in controlled airspace. You will also be able to connect to it with a mobile device to receive traffic and weather data.  If you are designing a steam gauge panel but require a radio, transponder and ADSB, you will probably find that the the cost is not significantly less than the Dynon HDX system.

MGL EMS-2 Engine Monitor

This digital engine monitor is a good fit if you are not using a Dynon or Garmin glass panel.  It will monitor the RPM, coolant temp, oil temp, EGT’s, and voltage.  It mounts in a standard 3 1/8″ instrument hole.   If you are using any of the EFIS units, the MGL engine monitor would be unnecessary.

Tachometer, Coolant Temp, Oil Temp, Oil Pressure Gauges

These would only be needed in a steam gauge panel. Any EFIS would include this data.

ASI UMA

This traditional airspeed instrument is made by UMA in the USA. It has both MPH and knots scales on it and can be lighted. This option is recommended as a back-up instrument.

Airspeed BK-3A

The BK-3A is a traditional airspeed indicator that reads in knots only.

MGL ALT-6

As above, this is a very nice unit for the price giving you both altitude and vertical speed. It works well, but it is also too bright for night flying.

MGL ASI-5

These units work well and are very light weight. For the price, they are a very good value. A consideration to keep in mind is that they are very bright and do not dim down enough for night flying. If you plan to fly at night, these are not recommended. A steam gauge airspeed with back light would be a better choice.

VSI BC-2A

This option is a traditional vertical speed indicator. It can be installed as primary in a steam gauge panel or as back-up for a glass panel system. Realistically, it’s not necessary for most applications.

Altimeter

This is a traditional altimeter, two pointer sensitive, 20,000 reading pressure in inches.  The price seems extreme because this is a TSO, made in the USA instrument.  The manufacturer we used previously a much lower price point has discontinued their model.  There is no other inexpensive sensitive altimeter on the market to date.

Compass

There are several options for a compass. You can use an Airpath wet compass in the panel in a 2 1/4” hole, or you can use the glare shield version on top of the dash where it has less interference. You can also select the vertical card compass which is a more accurate and easier-to-read style.

There are two options for the vertical card style, the Falcon (Chinese) and Precision (USA). I have found that the Falcon is not as stable and seems to move easily from any vibration.  The Precision unit is TSO’d, excellent quality, well stabilized and accurate.  The Airpath does very well for the money though. Keep in mind that either glass panel will have a compass sensor and display magnetic heading. A compass is useful for training or as a backup.

Winter Slip Indicator

This options comes in two versions: a 2 1/4” round or a rectangle. Keep in mind that either glass panel has this, so it really is redundant and a waste of panel space if selecting a glass panel system, but it is available.

Cables & Bracket for Radio Installation

Unless you are not installing a radio and transponder, this is required.

Antennas

If you are installing a com radio, the com radio antenna is required. If you are installing a transponder, the transponder antenna is required.

Lightspeed Zulu 3 Headset

The Zulu 3 is an excellent ANR (active noise reduction) headset. LightSpeed is arguably the best ANR headset brand on the market. The Zulu 3 is the more economical headset from LightSpeed. It is very quiet, comfortable and lightweight. It offers Bluetooth connectivity to connect to your phone or iPad and provides audio alerts from EFBs such as ForeFlight or Garmin Pilot as well as music. With the Bluetooth connection to your phone, you can also make calls through the headset. This is very convenient when contacting ATC for IFR clearance for example. The Zulu 3 is powered by two AA batteries and will last many hours between battery changes.

Lightspeed Delta Zulu Headset

 The Delta Zulu offers several valuable additions over the Zulu 3.  With safety being a high priority, LightSpeed has added a CO sensor that monitors the level of CO and produces an audible alert when it reaches a dangerous level.  A mobile app has also been created to sync with the Delta Zulu that will display the CO level.  Another very useful feature of the app is a hearing test that uses the headset to test the hearing in each ear, then programs the headset sound equalization to tune specifically for your hearing.  This greatly improves the clarity of communication as well as music through the headset.  The ANR (active noise reduction) feature has also been improved for an even quieter experience.  Yet another new feature is a removable, rechargeable lithium battery and optional desktop charger.  It also includes a AA battery pack for backup.  Overall, the Delta Zulu is a significant step forward in headset technology.

Safety

Parachute Cables & Bracket Pre-Rigged

If you think you might ever want to install a parachute system, or if you think you may sell the airplane at some point, it is a very good idea to select this option. If you have this, the brackets, cables and tethers are all installed in the airframe for the ballistic parachute. A parachute could be installed very easily in a matter of a few hours. Without this option, it would be very labor intensive to install and probably cost prohibitive.

Magnum Parachute

This is a ballistic parachute that is deployed instantly by a rocket propulsion system. It can work at altitudes as low as 100’. A parachute system is intended for use in the event of a major structural failure or control system failure where the airplane is no longer controllable. Another use might be in a spatial disorientation situation where the aircraft is out of control and cannot be recovered. It is not intended for use in an engine failure. In that event, you simply become a glider pilot and find a place to land. The argument for a parachute obviously is safety and peace of mind, sometimes more for loved ones of the pilot who do not understand aviation and are fearful of it. The drawbacks of the parachute are expense, added weight, and loss of baggage space.

To date, there has been one Aeroprakt that has deployed the parachute as a result of severe mountain turbulence causing an airframe failure. The details are unclear and the story seems a bit sketchy.  It occurred in France many years ago. The pilot sustained only minor injuries. The odds of a properly maintained Aeroprakt coming apart are probably similar to the odds of getting hit by an asteroid.  I think sometimes the parachute creates more risk than it eliminates.  People who have a parachute sometimes tend to fly and do maintenance like they have a parachute.  A parachute deployment may end far worse than flying the airplane down.  Once a parachute is deployed, the pilot no longer has any control of the situation and there is no guarantee that it will deploy properly.  It should be considered a last resort.  However, in certain rare situations, it could make the difference between living and dying.  This is an option that each owner will need to decide for themselves based on their risk tolerance.

Miscellaneous

Glider Tow Clutch Installation

This option allows the A22 to be used to tow gliders. The A22 makes a very capable tow plane with its slow stall speed and high thrust capability. It will tow single-seat gliders well, however it may be insufficient for two-seat gliders.

Price Sheet

This Excel price sheet is designed to easily determine a the cost of an A22LS aircraft with the desired options. Simply put an X in the center column of the options you want, and remove the X from the column of the options you do not want. There are a few options, USB ports for example, that require a number since you may select more than one. Once you have the options you want selected, you will see a total in Euros at the bottom. Enter the current exchange rate in the field for that and it will calculate the total in US Dollars including shipping. The exchange rate is locked in when the deposit is received and will not change regardless of the what the market does after that.

Sales Contract

This is an example of the sales contract that we use. It will be filled in with the specific buyer and aircraft information and signed when an aircraft is ordered.
