AoA and ASI low speed awareness

[PEI_3721]

The airspeed equivalent AOA – min speed, stick shake, stall etc, are computed without the need for aircraft mass by relating weight to Cl (Cl alpha curve) with use of look up tables.
This involves some compromise (linear assumptions) and different tables for each configuration.
Furthermore, some aircraft require adjustment for cg, which can be approximated by trim setting.
An example is in CONVERSION PRINCIPLE-ANGLE OF ATTACK TO AIRSPEED
