The International Cessna 170 Association

Every day I try to learn some thing new ,and today is one of them. I have seen a aircraft advertised with a lift reserve indicator . The idea seems ok but how does it work? Who makes them? So do they have a input of forward airspeed,AOA, density altitude, and weight of aircraft . Or simply is it a AOA gauge with a fancy name? does it take into flap configuration.so many questions, has any body fitted and flown with one ?

It’s a brand name of an angle of attack instrument; a digital stall warning with more than the one bit than our 170s came with.

Good description, Miles.
