An upset condition is now considered any time an airplane is diverting
from the intended airplane state. An airplane upset can involve pitch or roll
angle deviations as well as inappropriate airspeeds for the conditions.
The following actions represent a logical progression for recovering the
airplane. The sequence of actions is for guidance only and represents a
series of options to be considered and used dependent on the situation. Not
all actions may be needed once recovery is under way. If needed, use
minimal pitch trim during initial recovery. Consider careful use of rudder
to aid roll control only if roll control is ineffective and the airplane is not
stalled.
These actions assume that the airplane is not stalled. A stall condition can
exist at any attitude and can be recognized by one or more of the following:
• Stick shaker
• Buffet that can be heavy at times
• Lack of pitch authority
• Lack of roll control
• Inability to stop a descent.
If the airplane is stalled, first recover from the stall by applying and
maintaining nose down elevator until stall recovery is complete and stick
shaker stops.
