should the FPA selected by the pilot be the real angle (3 degrees) or the apparent angle (3.2 degrees)
Since
Vzbi = baro-inertial Vertical Speed
(inertial for accuracy in dynamic maneuvers & baro for stability in time)
GS = Groundspeed

Vzbi is computed from Vacc (Vertical acceleration from IR), Hi (Inertial altitude from IR) and Hb (Baro altitude from ADR).
then you should use the apparent 3.2 degrees due to the baro input.
