AOA
 

• Operate in or out of challenging strips?
• Operate a high performance, a high wing loaded, or light wing loaded STOL aircraft?
• Need full range AOA instrumentation but don't want ugly strips, probes, and vanes?
• Want to make consistently good landings resulting from proper AOA/airspeed control?
• Want a full range AOA based on known aerodynamic principles?
• Want to unlock the secrets of aircraft carrier pilots?
• Want critical angle and gear warning systems to increase your margin of safety?


Designed for experimental aircraft pilots, Angle-of-Attack unlocks Navy carrier pilots secrets and puts a priority on safety. All approaches should be flown at the same optimum approach angle of attack not the same IAS. We can now do precision approaches just like the military and airline pilots and accurately gauge Vx, Vy, Best glide, L/D max, and maximum endurance AOA because angle-of-attack is not a function of weight, bank angle, fuel load, density altitude and etc. This revolutionary angle of attack instrument is based on a long known aerodynamic principle. The AOA Professional includes a four color liquid crystal display and a aural voice system which warns of critically high AOA, gear position errors and installation/hardware errors. There are no ugly probes, vanes or protrusions to slow you down or accumulate ice.

Designed for those tight panels, requiring simplified features but still uses revolutionary patent pending sensing techniques. This angle of attack instrument is only 1/2" wide by 1 3/4" by 1 1/4" deep overall and will fit on or under your glare shield or between instruments as a panel mount in either the vertical or horizontal position. Enhance safety by installing the ultimate aerodynamic performance instrument. The display is a three color LED ladder and includes the same aural voice warnings as the AOA Professional. It can be powered with a 9V battery or by standard 14 or 28 aircraft bus systems. There are no ugly probes, vanes or protrusions to slow you down. This instrument has more resolution than the Navy's indexer used by Naval and Marine aviators today.

Our AOA instruments help do all these things and more. The AOA Pro and Sport are lightweight and easy to install. There are no ugly probes to slow you down or collect ice and no moving parts to break. These true full range AOA's with verbal warnings are affordable too.

Today's popular sport aircraft fly faster, higher, further, and with larger payloads. As a result, the stall speed, the approach speed, and other performance speeds can no longer be assumed to be constant. They actually never were. AOA provides pilots with a full range angle of attack indication on a color display and warns of high angles of attack visually and with a verbal message "Angle Angle Push".

Optimum approach to landing speeds vary with weight, bank angle, CG and even relative humidity. With the AOA instrument, we can now do precision approaches just like Navy aircraft carrier and airline pilots eliminating the requirement to compute performance speeds. AOA indication tells you where the airspeed is going to be, unlike the airspeed indicator that tells you where it was. Your aircraft stalls at the same AOA regardless of weight, temperature, altitude, or center of gravity and bank angle. Your stall indicated airspeed varies significantly with all the above. For any given airfoil, other performance parameters such as best lift to drag, best glide, maximum endurance and maximum maneuvering performance also occur at known AOAs.

The AOA Professional features a small liquid crystal four color AOA indicator. The AOA Sport features an even smaller three color LED display. Both include Aural Warning systems that will help you fly more precisely and safely. Both feature digital processing at a cost that is comparable or less than the simple stall switch tab seen on many production aircraft.

The AOA Professional includes a gear position warning system, which says "Landing Gear" when the gear is not down for landing. The AOA Sport will fit anywhere! You can mount it between instruments vertically; or below or on top of the glare shield horizontally. One year limited warranty beginning from when you first fly AOA. Order now and fly safe!
