For a climb RA in landing configuration:
Upset Recovery
An upset can generally be defined as unintentionally exceeding the following
conditions:
• Pitch attitude greater than 25 degrees nose up, or
• Pitch attitude greater than 10 degrees nose down, or
• Bank angle greater than 45 degrees, or
• Within above parameters but flying at airspeeds inappropriate for the
conditions.
The following techniques 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 depending on the situation. Not all actions may
be necessary once recovery is under way. If needed, use pitch trim sparingly.
Careful use of rudder to aid roll control should be considered only if roll control
is ineffective and the airplane is not stalled.
These techniques assume that the airplane is not stalled. A stall condition can exist
at any attitude and may be recognized by continuous stick shaker activation
accompanied by one or more of the following:
• Buffeting which could be heavy at times
• Lack of pitch authority and/or roll control
• Inability to arrest descent rate.
If the airplane is stalled, recovery from the stall must be accomplished first by
applying and maintaining nose down elevator until stall recovery is complete and
stick shaker activation ceases.
Pilot Flying Pilot Not Flying
Disengage the autopilot and
autothrottle. Advance thrust levers
forward to ensure maximum thrust is
attained and call for FLAPS 15.
Smoothly adjust pitch to satisfy the RA
command. Follow the planned lateral
flight path unless visual contact with
the conflicting traffic requires other
action.
Verify maximum thrust set. Position flap
lever to 15 detent.
After positive rate of climb established,
call for GEAR UP.
Position gear lever up.
Attempt to establish visual contact. Call out any conflicting traffic.
