Holy Micro! has introduced Absolute AoA, a new Angle of Attack (AoA) system.
Officials with the company, which also produces the SkyVoice Alert 500, SkyVoice Glassy Guide 400, and SkyVoice Glassy Guide 400 Portable, note the FAA has emphasized the critical role of Angle of Attack (AoA) alerting systems in improving aviation safety.
“In its Special Airworthiness Information Bulletin (SAIB: 2024-07), the FAA highlights that AoA indicators significantly enhance situational awareness, helping pilots avoid stalls and loss-of-control incidents,” officials noted. “These systems are particularly vital during takeoff, landing, and low-speed maneuvers, when the risk of aerodynamic stall is greatest.”
According to company officials, the Absolute AoA offers “real-time, accurate Angle of Attack data for all phases of flight — takeoff, climb, cruise, and landing — enhancing safety, efficiency, and pilot confidence far beyond just stall prevention.”
Utilizing multiple sensors, the system calculates and calibrates a normalized pressure ratio, an accurate method validated through extensive studies and flight tests, company official explained.
“This technology ensures dependable AoA indications, unaffected by density altitude, loading conditions, or flap settings,” company officials said. “As a result, pilots receive accurate data not just near stall speed, but also across key V-speeds including Vx, Vy, Va, and Best Glide.”
Absolute AoA also integrates LiDAR technology that automatically detects flap position and landing configuration without requiring any physical connection to the flap system. This feature enhances the system’s accuracy during takeoff, approach and landing, providing seamless adjustments as the aircraft’s configuration changes, company officials explained.
Pilots and installers can choose between a wireless option, completed in under one hour, or a wired option that typically takes three to four hours using existing inspection plates under the wing, according to company officials. The wireless option can take power from the aircraft’s wing or navigation lights, reducing installation time, officials added.
For display, Absolute AoA provides multiple customizable options, including 2.2-inch, 2.4-inch, 2.8-inch and bar-style touch displays, offering real-time visual feedback to enhance situational awareness.
The product, which is priced at $2,400, is patent pending and FAA NORSEE approval in progress, officials added.
