CABIN PRESSURIZATION CONTROLLER FAILURE
IF CABIN DOES NOT PRESSURIZE AFTER TAKEOFF
1. Thrust Attenuator Switch - STOW.
NOTE
• Failure of the cabin to pressurize after takeoff indicates possible failure of a squat switch in the ground mode which could result in thrust attenuators being deployed in flight.
• LANDING DISTANCES WILL BE INCREASED. REFER TO ATTENUATOR UNLOCKED PRIOR TO LANDING CHECKLIST.
IF CABIN ALTITUDE IS NOT BEING MAINTAINED
1. Pressurization Control - MANUAL. Control cabin altitude with the MANUAL toggle valve.
IF CABIN PRESSURE IS MAINTAINED, BUT AMBER FAIL ANNUNCIATOR IN PRESSURE CONTROLLER IS ILLUMINATED (Probable loss of air data computer input, auto-schedule inoperative.)
1. Pressurization Controller - SELECT CA, (Cabin Altitude) or FL, (Flight Level).
2. Pressurization SET ALT Knob - AS DESIRED (FL or CA).
3. Prior to Descent - SET ALT Knob (CA), DESTINATION PRESSURE ALTITUDE + 200 FEET.
