Lift Reserve Indicator
Lift reserve indicator (LRI) is a very interesting concept described in great detail on Mountain Flying website.
Its basic principle is similar to the angle of attack, but instead of an angle it shows your “position” on the power curve.
Hardware-wise the LRI is practically identical to the AoA indicator except it does not require airspeed sensor.
Of course, the software is different but the basic principle of measuring the differential pressure between two angled ports is the same.
