4 important questions on Memory Items QRH

Aborted Engine Start

Condition: On the ground, an aborted engine start is needed.
Objective: To shut down the engine and motor it.

Engine start lever (affected engine) . . . CUTOFF

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 (if installed and operative) illuminates.

1. Don oxygen masks and set regulators to 100%
2. Establish crew communications
3. Pressurization mode selector . . . MAN
4. Outflow VALVE switch . . . Hold in CLOSE until the outflow VALVE indication shows fully closed
5. If cabin altitude is uncontrollable

Passenger signs . . . ON
PASS OXYGEN switch . . . ON

Go to the Emergency Descent checklist

Engine Limit or Surge or Stall

Condition: One or more of these occur:

Engine indications are abnormal
Engine indications are rapidly approaching or exceeding limits
Abnormal engine noises are heard, possibly with airframe vibrations
There is no response to thrust lever movement or the response is abnormal
Flames in the engine inlet or exhaust are reported

Objective: To attempt to recover normal engine operation or shut down the engine if recovery is not possible.

1. Autothrottle (if engaged) . . . Disengage
2. Thrust lever (affected engine) . . . Confirm . . . Retard until engine indications stay within limits or the thrust lever is closed

Loss of Thrust On Both Engines

Condition: Both of these occur:

Both engines have a loss of thrust
Both ENG FAIL alerts show

Objective: To restart at least one engine

1. ENGINE START switches (both) . . . FLT
2. Engine start levers (both) . . . CUTOFF
3. When EGT decreases:

Engine start levers (both) . . . IDLE detention

4. 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.
