AOA indicators, proven to prevent stalls, are gaining traction despite slow pilot adoption.
Loss-of-control accidents—most often caused by stalls—remain the leading cause of fatal general aviation crashes.
To reduce that risk, Alpha Systems, founded by pilot Mark Korin, develops affordable Angle of Attack (AOA) indicators that provide real-time feedback on how close a wing is to its critical stall angle.
Unlike airspeed, which can be unreliable in high-workload situations, AOA shows actual wing performance during takeoff, landing, and maneuvering.
The NTSB and FAA have strongly endorsed wider use of AOA systems, and FAA NORSEE approval allows for straightforward installation with only a logbook entry.
Still, many pilots have been slow to adopt the technology, viewing it as unnecessary.
With growing advocacy and integration into modern glass cockpits, AOA indicators are gaining traction as one of the most effective safety upgrades for light aircraft.
Los indicadores de AOA, que se ha demostrado que previenen los estancamientos, están ganando terreno a pesar de la lenta adopción como modelo piloto.
