Hi HN39,
I think the BUSS essentially uses the same equation in reverse, solving for airspeed from sensed LF and AoA.
It's not that clever.
It simply displays a sensible angle of attack as the "green" sector. Other angles of attack as orange and red. It is orientated so that the red sector (with high angle of attack) is at the bottom of the scale, etc.
Hi JD-EE,
He remarked about high speed. He was tilted back and drew the wrong confusion from his senses.
Pilots can only sense accelerations - not speed. The sensation of high speed was due to the unusual air noise around the cockpit sounding like they were going very fast.
