IF Cabin Altimeter Is Inoperative:
1.
Note aircraft altitude and read ambient pressure from Table.
2.
Read indicated cabin differential on gauge.
3.
Add indicated cabin differential to ambient pressure from Table.
4.
Re-enter table with this sum and read proper cabin altitude. IF Differential Pressure Indicator is Inoperative:
1.
Note aircraft altitude and read ambient pressure from Table.
2.
Read indicated cabin altitude on gauge.
3.
Note ambient pressure for indicated cabin altitude from Table.
4.
Subtract ambient pressure for indicated cabin altitude (item 3) from ambient pressure for aircraft altitude (item 1) to get proper cabin differential pressure.

DISPATCH FOR FLIGHT WITH AIR
CONDITIONING SHUTOFF INOPERATIVE
Note: One or both air conditioning packs may be used as required during ground operation.
- - - - - BEFORE TAKEOFF- - - - -
AIR COND SHUTOFF Switch......................................................... OVRD
AIR CONDITIONING SUPPLY Switches...............................BOTH OFF
CABIN ALT Control Lever..................................POSITION AND LOCK
Position the Cabin Press Control lever opposite the 40 flap setting and lock in manual mode.
Note: Add .02 EPR to the takeoff EPR gauge settings.
- - - - - AFTER TAKEOFF- - - - -
AIR CONDITIONING SUPPLY Switch.......................................ONE ON
Do not select ON until complete flap retraction or a minimum altitude of 400 feet.
CABIN PRESS Controller.................................................................AUTO
Remaining AIR CONDITIONING SUPPLY Switch.............................ON
Caution: If an engine fails enroute, both air conditioning packs must be turned off prior to landing. If an engine fails after the landing gear extension, turn off both packs immediately.

Rev. 05/15/95 #23 Continental Flight Manual
DISPATCH FOR FLIGHT WITH ONE PACK INOPERATIVE
Inoperative AIR COND SUPPLY Switch ............................................ OFF
AUTOTHROTTLE Switch .................................................................. OFF
AIR COND SHUTOFF Switch..........................................................AUTO
Takeoff EPR Setting......................................................................ADJUST
Add .02 EPR to the takeoff EPR setting of the engine with the inoperative pack. TRC (if installed) will provide EPR setting for engine with operative pack. If ART is selected, use normal EPR settings; if ART is OFF, use maximum EPR settings.
Cruise Altitude/Fuel Consumption......................................RECOMPUTE
Limit flight altitude to 25,000 feet pressurized or 10,000 feet
unpressurized.
NO SMOK Sign ......................................................................................ON
No smoking is allowed on ground or in flight with one pack inoperative. Note: Reference MEL for a both-packs-off option.
* * * *
DISPATCH FOR FLIGHT UNPRESSURIZED
Note: Ram air system must be operable if either pack is inoperative.
CABIN ALT Control Lever........................................................ MANUAL
Outflow Valve Position Indicator ........................................VALVE OPEN
Push and rotate the cabin altitude control wheel until the valve position indicator moves to the full aft position. The indicator should remain in this position throughout the flight.
Cabin Pressurization Control CB (H-2, J-2, U-22, W-22) ....................................................................... PULL
Flight Altitude......................................................LIMIT TO 10,000 FEET
Note: At altitudes above 9,500 feet, expect CABIN PRESS and MASTER WARNING lights to come on. On aircraft with voice, expect aural warning and horn to sound. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：MD-80 Flight Manual 麦道80飞行手册 1(66)
