GASPER OUTLETS . . . . . . . . . . . . . . . . . . . . . . . . . . . OPEN
CAUTION: Do not open any flight deck window. Keep the
cabin door closed.
If smoke/fumes are uncontrollable:

At 14,000 feet or below:
PRESSURIZATION MODE SELECTOR . . . . . . . . MAN
OUTFLOW VALVE SWITCH . . . . . . . . . . . . . . . . OPEN
Position outflow valve to full open. This causes
the cabin airflow to carry smoke/fumes aft.
Note: On airplanes with DCPCS, the outflow valve
can take up to 20 seconds to open.
Plan to land at the nearest suitable airport.
If packs are off and smoke/fumes source is confirmed to be
on the flight deck:
CAUTION: Window should not be opened unless the
source is confirmed to be originating on the
flight deck.

Condition: The stabilizer fails to respond to electric trim inputs.
MANUAL TRIM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .APPLY
Apply steady pressure on the manual trim handles until
the desired trim is attained.
If required, use force to cause the disconnect clutch to
disengage. Approximately 1/2 turn of the stabilizer trim
wheel may be needed.
Note: A maximum two-pilot effort on the trim wheels will not
cause a cable or system failure.
Note: Handle should be folded inside stabilizer trim wheel
when not in use.
If the trim wheel moves when released:
STABILIZER TRIM AUTOPILOT
CUTOUT SWITCH . . . . . . . . . . . . . . . . . . . . . . . . . . CUTOUT
[Autopilot is not available.]
Maintain in-trim airspeed until the start of the approach.
To reduce the force required to move the stabilizer, use
an airspeed which results in an in-trim condition.
Plan a flaps 15 landing.
Set VREF 15.
Establish landing configuration early.
Note: Anticipate higher than normal elevator forces during
approach and landing.
Note: The thrust reduction at flare will cause a nose down
pitch.
