After positive rate of climb
established, call for GEAR UP.
Position gear lever up.
Attempt to establish visual contact. Call out any conflicting traffic.

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 the actions may be necessary once recovery is underway. 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 stalled
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.
Nose High Recovery
Pilot Flying Pilot Monitoring
• Recognize and confirm the situation.
• Disconnect autopilot and autothrottle.
• Apply as much as full nose down
elevator.
• *Apply appropriate nose down
stabilizer trim.
• Reduce thrust.
• *Roll (adjust bank angle) to obtain a
nose down pitch rate.
• Complete the recovery:
• when approaching the horizon, roll to
wings level
• check airspeed and adjust thrust
• establish pitch attitude.
• Call out attitude,
airspeed and altitude
throughout the
recovery.
• Verify all required
actions have been
completed and call
out any omissions.

Nose Low Recovery
WARNING: * EXCESSIVE USE OF PITCH TRIM OR
RUDDER MAY AGGRAVATE AN UPSET
SITUATION OR MAY RESULT IN LOSS OF
CONTROL AND/OR HIGH STRUCTURAL
LOADS.
Windshear
Windshear Caution
For predictive windshear caution alert: (“MONITOR RADAR DISPLAY”
aural)
Windshear Warning
Predictive windshear warning during takeoff roll: (“WINDSHEAR
AHEAD, WINDSHEAR AHEAD” aural)
• Prior to V1, reject takeoff.
• After V1, perform the Windshear Escape Maneuver.
Pilot Flying Pilot Monitoring
• Recognize and confirm the situation.
• Disconnect autopilot and autothrottle.
• Recover from stall, if required.
• *Roll in the shortest direction to wings
level (unload and roll if bank angle is
more than 90 degrees).
• Recover to level flight:
• apply nose up elevator
• *apply nose up trim, if required
• adjust thrust and drag as required.
• Call out attitude,
airspeed and altitude
throughout the
recovery.
• Verify all required
actions have been
completed and call
out any omissions.
Pilot Flying Pilot Monitoring
• Maneuver as required to avoid the windshear.

Windshear encountered during takeoff roll:
• If windshear is encountered prior to V1, there may not be sufficient
runway remaining to stop if an RTO is initiated at V1. At VR,
rotate at a normal rate toward a 15 degree pitch attitude. Once
airborne, perform the Windshear Escape Maneuver.
• If windshear is encountered near the normal rotation speed and
airspeed suddenly decreases, there may not be sufficient runway
left to accelerate back to normal takeoff speed. If there is
insufficient runway left to stop, initiate a normal rotation at least
2,000 feet before the end of the runway even if airspeed is low.
Higher than normal attitudes may be required to lift off in the
remaining runway. Ensure maximum thrust is set.
Predictive windshear warning during approach: (“GO-AROUND,
WINDSHEAR AHEAD” aural)
• perform Windshear Escape Maneuver or, at pilot’s discretion,
perform a normal go-around.
Windshear encountered in flight:
• perform the Windshear Escape Maneuver.
Note: The following are indications the airplane is in windshear:
