Maneuvering in Slow Flight
When the desired pitch attitude and airspeed have been established in straight-and-level slow flight, the pilot must maintain awareness of outside references and continually cross-check the airplane’s instruments to maintain control.
The pilot should note the feel of the flight controls, especially the airspeed changes caused by small pitch adjustments, and the altitude changes caused by power changes.
The pilot should practice turns to determine the airplane’s controllability characteristics at this low speed.
During the turns, it will be necessary to increase power to maintain altitude.
Abrupt or rough control movements during slow flight may result in a stall.
The pilot should also practice climbs and descents by adjusting the power when stabilized in straight-and-level slow flight.
The pilot should note the increased yawing tendency at high power settings and counter it with rudder input as needed.
To exit the slow flight maneuver, follow the same procedure as for recovery from a stall: apply forward control pressure to reduce the AOA, maintain coordinated flight and level the wings, and apply power as necessary to return to the desired flightpath.
As airspeed increases, clean up the airplane by retracting flaps and landing gear if they were extended.
A pilot should anticipate the changes to the AOA as the landing gear and flaps are retracted to avoid a stall.
Common errors in the performance of slow flight are:
• Failure to adequately clear the area
• Inadequate back-elevator pressure as power is reduced, resulting in altitude loss
• Excessive back-elevator pressure as power is reduced, resulting in a climb followed by a rapid reduction in airspeed
• Insufficient right rudder to compensate for left yaw
• Fixation on the flight instruments
• Failure to anticipate changes in AOA as flaps are extended or retracted
• Inadequate power management
• Inability to adequately divide attention between airplane control and orientation
• Failure to properly trim the airplane
• Failure to respond to a stall warning
