AOA Pro II, Wing Port System, Angle of Attack Instrument, by Advanced Flight

AOA ADVANCED PRO

ADVANCED PRO III AOA senses dynamic pressures with two pressure ports in the Probe. Our patented technology computes the current Angle of Attack, taking into account flap settings and dynamic pressures. This technique eliminates the need for moving parts with the added benefit of better reliability. Extensive engineering and wind tunnel testing were used to develop the AOA probe.

The Pro III is the top of the line full range AOA System comparable to instruments costing tens of thousands of dollars more. It includes a voice warning system announcing warnings of high angles of attack and landing gear position errors. The dimmable four color liquid crystal display shows you angle of attack in an analog and digital format. The donut is the target for the optimum AOA flown for all approaches and is green only when in landing configuration (Flaps). The “X” on the green bar is the best engine out glide AOA. The red chevrons indicate dangerously high AOAs.

AOA Sport

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.

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.
