This will back up the automatic system to assure signal is sent to deploy passenger masks. Do not hold in EJECT more than 5 seconds.
Level off Altitude....................................................... SET & ARM
Level off altitude should be a maximum of 14,000 feet or MEA, whichever is higher. Further descent to 10,000 feet or below should be considered if weather, terrain, and fuel permit.
Altimeters ................................................................................ SET
Set to a local setting below 18,000 feet.
PA .............................................. ADVISE F/A’S OF SITUATION
Advise Flight Attendants they need to be on oxygen until
advised otherwise.

Speedbrakes ............................................................RETRACTED
Crew Oxygen Regulators ..................................... AS REQUIRED
Flight crew must use oxygen when cabin altitude is above 10,000 feet. To conserve oxygen, position NORMAL / 100% selector to NORMAL.
PA ........... ADVISE F/A’S OXYGEN NO LONGER REQUIRED
The new course of action is based on weather, oxygen, fuel
remaining, and available airports.

EMERGENCY DESCENT PROCEDURE
General Considerations
This maneuver is used to bring the aircraft down smoothly to a safe cabin altitude in the minimum time with the least passenger discomfort. It is intended as a specialized case to cover an uncontrollable loss of cabin pressurization. Use of the autopilot is recommended. When it is used for other than pressurization problems or contamination of cabin atmosphere, the oxygen procedures may be omitted.
Don oxygen masks and establish crew communication at the first indication of a loss of cabin pressurization. Verify that cabin pressure is uncontrollable and attempt to determine if there is structural damage. If structural damage is confirmed or suspected, limit airspeed in the descent to current speed or less. If conditions permit, the cabin crew will be advised, on the PA system, of impending rapid descent.
All immediate action items are to be accomplished by memory. Either pilot will call out any items not completed. Perform the entry procedure deliberately and methodically. Do not be distracted from flying the aircraft.
Emergency Descent Maneuver
Using Autopilot and Autothrottles
.
Rotate the vertical speed wheel to 4000-6000 FPM down.
.
Assure throttles are fully aft at idle.
.
Fully extend the speed brakes.
.
Press the IAS / MACH (MACH HOLD on some aircraft) button when .80-.82 (.75-.79 turbulent air or structural damage) mach is reached.
.
Select and arm the level off altitude.
.
Press the IAS / MACH (IAS HOLD on some aircraft) button when 320-340 (275-285 turbulent air or structural damage) KIAS is reached (approximately FL 270).
.
Set desired level off airspeed into SPD/MACH window.
.
Monitor autopilot / autothrottles during level off.
.
Retract speedbrakes prior to reaching minimum maneuver speed.
Manually Flown
.
Use FGS commands as above to provide FD guidance, if desired. (i.e. “Vertical speed 6000 down”, “Mach hold”).
.
Close throttles fully.
.
Fully extend the speed brakes.
.
Lower pitch to maximum of 10. via wings level pushover or turn.
.
Hold speed of .80-.82 Mach/320-340 KIAS (.75-.79 Mach/275-285 KIAS turbulent air or structural damage).
.
Assure level off altitude is armed.
.
Start reducing rate of descent 2000 feet above level off.
.
Retract speed brakes prior to reaching minimum maneuver speed.
