or initial buffet is the upper pitch attitude limit. Flight at
intermittent stick shaker may be required to obtain positive
terrain separation. Smooth, steady control will avoid a pitch
attitude overshoot and stall.
Note: Do not use flight director commands.
Note: * Maximum thrust can be obtained by advancing the thrust levers
full forward if the EECs are in the normal mode. If terrain contact
is imminent, advance thrust levers full forward.
Note: If positive visual verification is made that no obstacle or terrain
hazard exists when flying under daylight VMC conditions prior
to a terrain or obstacle (as installed) warning, the alert may be
regarded as cautionary and the approach may be continued.
Traffic Avoidance
Immediately accomplish the following by recall whenever a TCAS traffic
advisory (TA) or resolution advisory (RA) occurs.
WARNING: Comply with RA if there is conflict between RA and air
traffic control.
Pilot Flying Pilot Monitoring
• Disconnect autopilot.
• Disconnect autothrottle(s).
• Aggressively apply maximum* thrust.
• Simultaneously roll wings level and
rotate to an initial pitch attitude of 20°.
• Retract speedbrakes.
• If terrain remains a threat, continue
rotation up to the pitch limit indicator or
stick shaker or initial buffet.
• Assure maximum*
thrust.
• Verify all required
actions have been
completed and call out
any omissions.
• Do not change gear or flap configuration
until terrain separation is assured.
• Monitor radio altimeter for sustained or
increasing terrain separation.
• When clear of the terrain, slowly
decrease pitch attitude and accelerate.
• Monitor vertical speed
and altitude (radio
altitude for terrain
clearance and
barometric altitude for
a minimum safe
altitude).
• Call out any trend
toward terrain contact.

WARNING: Once an RA has been issued, safe separation could be
compromised if current vertical speed is changed,
except as necessary to comply with the RA. This is
because TCAS II-to-TCAS II coordination may be in
progress with the intruder aircraft, and any change in
vertical speed that does not comply with the RA may
negate the effectiveness of the other aircraft’s
compliance with the RA.
Note: If stick shaker or initial buffet occurs during the maneuver,
immediately accomplish the APPROACH TO STALL
RECOVERY procedure.
Note: If high speed buffet occurs during the maneuver, relax pitch force
as necessary to reduce buffet, but continue the maneuver.
Note: Do not use flight director commands (integrated cue)/flight
director pitch commands (split cue) until clear of conflict.
For TA:
For RA, except a climb in landing configuration:
WARNING: A DESCEND (fly down) RA issued below 1000 feet
AGL should not be followed.
Pilot Flying Pilot Monitoring
Look for traffic using traffic display as a guide. Call out any conflicting traffic
If traffic is sighted, maneuver as required.
Pilot Flying Pilot Monitoring
If maneuvering is required, disengage the
autopilot and autothrottle. Smoothly adjust
pitch and thrust to satisfy the RA
command. Follow the planned lateral flight
path unless visual contact with the
conflicting traffic requires other action.
Attempt to establish visual contact. Call out any conflicting traffic.

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 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
