point?
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 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 loses 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.
Once a good OAA Set point has
been achieved, the pilot
continues to STEP 2 and MUST
enter into the Cruise Calibration
Mode or repeat the OAA Set
point Operation.
