I still haven’t completely wrapped my mind around how Aspen Avionics’ recently introduced angle-of-attack system for light airplanes works. And because Aspen is seeking a patent for the unique, software-only approach to AOA indication, the company isn’t ready to reveal all the details. But I had the chance to fly with the system in the blue skies over Lakeland, Florida, yesterday and came away convinced that the technology really does work as advertised.
What’s so unusual about Aspen’s AOA indicator is that it doesn’t rely on any sensors on the wing or even extra wiring or plumbing as other AOA systems do. Instead, your local avionics shop simply uploads new software, inputs aircraft weight information and you go fly once with the technology to calibrate the system. Then you’re in business.
