In-Flight calibration requires the pilot to climb to a safe
altitude for slow flight maneuvers. The pilot will fly the
aircraft to the condition of Optimum Alpha Angle (OAA):
Aircraft is at the Optimum Alpha Angle (OAA), when:
1. Aircraft is at a safe altitude for slow flight
maneuvers.
2. Minimum controllable flight, lower power setting,
(such as a down wind or landing pattern power
setting).
3. Able to hold altitude, 0 Vertical Speed, not
descending, zero sink (5 to 10 fpm climb OK if
your aircraft looses flight control stability at 0
VS).
4. Full aileron, elevator and rudder control, not in a
buffet, pilot to identify the set point by pitching back
slowly to a pitch no longer able to climb but able to
hold altitude with full control of the airplane.
