—
Condition:
On the ground, an aborted engine start is needed.

Airspeed Unreliable
—
Condition:
Airspeed or Mach indications are suspected to be unreliable. (Items which might indicate unreliable airspeed are listed in the Additional Information section.)
Additional information:
One or more of the following may be associated with unreliable airspeed or Mach indications:
- Difference between captain and first officer airspeed indications
- Speed/altitude information not consistent with pitch attitude and thrust setting
- Blank or fluctuating airspeed indication
- Continuous or intermittent stick shaker
- IAS DISAGREE alert
- ALT DISAGREE alert
- AOA DISAGREE alert
- SPD failure flag
- SPD LIM failure flag
- Erroneous minimum speed bars
- Erroneous maximum speed bars
- Airspeed low aural
- Airspeed low PFD indications on one side
- Overspeed warning
- Erroneous Flight Director (FD) pitch command bar
- Radome damage or loss
If the AOA DISAGREE alert is shown, one or more of the following flight deck effects can occur:
- Erroneous Pitch Limit Indicator (PLI)
- Windshear alerts
- Autoslat operation
- Autopilot (if engaged) … Disengage
- Autothrottle (if engaged) … Disengage
- F/D switches (both) … OFF
- Set the following gear up pitch attitude and thrust:
Flaps extended … 10’ and 80% N1
Flaps up … 4’ and 75% N1
APU FIRE
—
Condition:
Fire is detected in the APU.
- APU fire switch … Confirm … Pull, rotate to the stop, and hold for 1 second
- APU switch … OFF
CABIN ALTITUDE WARNING or Rapid Depressurization
— Condition: One or more of these occur: - A cabin altitude exceedance - In flight, the intermittent cabin altitude/configuration warning horn sounds or a CABIN ALTITUDE light illuminates.
- Don oxygen masks and set regulators to 100%.
- Establish crew communications.
- Pressurization mode selector … MAN
- Outflow VALVE switch … Hold in CLOSE until the outflow VALVE indication shows fully closed
If cabin altitude is uncontrollable: - Passengers signs ... ON - PASS OXYGEN switch ... ON - Go to the Emergency Descent checklist on page 0.1 ••••
Emergency Descent
— Condition: One or more of these occur: - Cabin altitude cannot be controlled - A rapid descent is needed.
- Announce the emergency descent. The pilot flying will advise the cabin crew, on the PA system, of impending rapid descent. The pilot monitoring will advise ATC and obtain the area altimeter setting.
- Passenger signs … ON
- Without delay, descend to the lowest safe altitude or 10,000 feet, whichever is higher.
- ENGINE START switches (both) … CONT
- Thrust levers (both) … Reduce thrust to minimum or as needed for anti-ice
- SPEED BRAKE … FLIGHT DETENT
(If structural integrity is in doubt, limit speed as much as possible and avoid high maneuvering loads.)
- Set target speed to Mmo/Vmo.
ENGINE FIRE or Engine Severe Damage or Separation
— Condition: One or more of these occur: - Engine fire warning - Airframe vibrations with abnormal engine indications - Engine separation.
- Autothrottle (if engaged) … Disengage
- Thrust lever (affected engine) … Confirm … Close
- Engine start lever (affected engine) … Confirm … CUTOFF
- Engine fire switch (affected engine) … Confirm … Pull
If the engine fire switch or ENG OVERHEAT light is illuminated:
- Engine fire switch … Rotate to the stop and hold for 1 second
Engine Limit or Surge or Stall
—
Condition:
- Engine indications are abnormal
- Engine indications are rapidly approaching or exceeding the limits
- Abnormal engine noises are heard, possibly with airframe vibration
- There is no response to thrust lever movement or the response is abnormal
- Flames in the engine inlet or exhaust are reported.
- Autothrottle (if engaged) … Disengage
- Thrust lever (affected engine) … Confirm … Retard until engine indications stay within limits or the thrust lever is closed
ENGINE OVERHEAT
—
Condition:
An overheat is detected in the engine.
- Autothrottle (if engaged) … Disengage
- Thrust lever (affected engine) … Confirm … Close
If the ENG OVERHEAT light stays illuminated:
- Go to the ENGINE FIRE or Engine Severe Damage or Separation checklist on page 8.2
••••
TAKEOFF CONFIGURATION
—
Condition:
On the ground, the intermittent cabin altitude/configuration warning horn sounds or a TAKEOFF CONFIG light illuminates when advancing the thrust levers to takeoff thrust.
- Assure correct airplane takeoff configuration.
••••
Loss Of Thrust On Both Engines
—
Condition:
- Both engines have a loss of thrust
- Both ENG FAIL alerts show.
- ENGINE START switches (both) … FLT
- Engine start levers (both) … CUTOFF
When EGT decreases:
- Engine start levers (both) … IDLE detent
If EGT reaches a redline or there is no increase in EGT within 30 seconds:
- Engine start lever (affected engine) … Confirm … CUTOFF, then IDLE detent
If EGT again reaches a redline or there is no increase in EGT within 30 seconds, repeat as needed.
Runaway Stabilizer
—
Condition:
Uncommanded stabilizer trim movement occurs continuously or in a manner not appropriate for flight conditions.
- Control column … Hold firmly
- Autopilot (if engaged) … Disengage
- Autothrottle (if engaged) … Disengage
- Control column and thrust levers … Control airplane pitch attitude and airspeed
- Main Electric Stabilizer trim … Reduce control column forces
If the runaway stops after the autopilot is disengaged:
- Do not re-engage the autopilot or autothrottle.
••••
If the runaway continues after the autopilot is disengaged:
- STAB TRIM cutout switches (both) … CUTOUT
If the runaway continues:
- Stabilizer trim wheel … Grasp and hold
LANDING CONFIGURATION
—
Condition:
In flight, the steady warning horn sounds.
- Assure correct airplane landing configuration.
