Available as two different standalone AOA systems, the AOA Pro or AOA Sport, or integrated into your AFS EFIS, AOA instrumentation is something every aircraft builder should consider...
• 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
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?
Our AOA instruments help do all these things and more.
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.
Nearly one-half of experimental and over one-fourth of certified aircraft fatalities are the result of stalls
and spins. The killer-turn from base to final, distractions from “flying the aircraft” and lack of raw AOA information
all contribute to these statistics. Gauging angle-of-attack is the pilot’s best tool for monitoring
aerodynamic performance. Best glide, maximum range, approaches and stalls are all functions of AOA,
not airspeed. Optimum approach to landing speeds vary with weight, bank angle, CG and even relative
humidity. With our AOA instrument, you can fly precision approaches just like Navy and airline pilots,
and eliminate the need to compute performance speeds. AOA indication tells where the airspeed is
going to be, unlike the airspeed indicator that tells where it was.
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.
