(81 cards)
“land as soon as possible” expectations
Declare an emergency
Land at the nearest suitable airfield
“Land as soon as practical” expectations
Mission is to be terminated
An immediate landing at the nearest adequate airfield may not be necessary
Ground evacuation alarm bell signal
One long sustained ring
Bailout alarm bell signal
Prepare to bailout - three short rings
Bailout - one long sustained ring
Ditching or crashing landing alarm bell signal
Prepare to ditch/crash land - six short rings
Brace for impact - one long sustained ring
12 Engine shutdown conditions
Certain propeller malfunctions Uncontrollable rise in TIT Uncontrollable rise in oil temperature Uncontrollable drop in oil pressure Uncontrollable power Unusual vibration or roughness Nacelle overheat Turbine overheat Throttle control cable failure START VALVE OPEN light illuminates Engine fire Excessive visible fuel leak
Engine shutdown procedure
CONDITION LEVER “FEATHER” (CP)
FIRE HANDLE “PULLED” (CP)
AGENT “DISCHARGED” (FOR FIRE OR NACELLE OVERHEAT)
- land as soon as practical
If during the ESP, the fire or nacelle overheat condition persists after the first fire bottle is discharged, what should you do?
Isolate the wing by:
Placing engine bleed air switch to OFF
Closing the divider valve
If condition persists, discharge the remaining bottle on command of the pilot
APU EMERGENCY SHUTDOWN
FIRE HANDLE “PULLED” (E)
AGENT “DISCHARGED” (FOR FIRE) (E)
If during the APU EMERGENCY SHUTDOWN, the fire condition persists what should you do?
Isolate #1 and #2 by placing bleed air switches to OFF and closing the divider valve
If fire continues, discharge remaining bottle
Possible indicators of a bleed air leak:
Fire warning lights Low torque Erratic engine instruments Erratic electrical equipment Wing overheat Reduced bleed air manifold pressure
Note: bleed air failure is a land as soon as possible condition
Can you maintain aircraft pressurization with the bleed air switches turned OFF?
No, because airflow to both air conditioner units is lost
Should you open the APU bleed air valve after landing with an uncontrolled loss of bleed air that could not be isolated?
No, you could repressurize the leaking area
Steps for wing overtemp indication:
Wing anti-icing - OFF
If condition persists after 1 minute…
Affected wing bleed air switches - OFF
Bleed air divider valve - closed
APU/external air - OFF
Can a single air condition unit, augmented with under floor heat, maintain maximum cabin differential pressure?
Yes
Uncontrolled cabin pressure increase steps and cause:
Will only occur with a stuck outflow valve
- Turn off engine bleed air, one at a time
- Control px by turning bleed air on/off
- Shut down one air conditioning system if necessary to expedite depressurization
START VALVE OPEN LIGHT illuminated on the ground:
GROUND STOP and close the respective bleed air valve
ENGINE FIRE on the ground:
GROUND IDLE, ESP
Tailpipe fire/torching during start:
GROUND STOP, motor the engine
Note: if flames spread beyond the tailpipe, ESP
Tailpipe fire during flight:
Indicated by loss of oil quantity and/or heavy smoke
Monitor during flight and ESP prior to landing
Turbine overheat on the ground:
GROUND IDLE/GROUND STOP
Turbine overheat in the air:
Retard throttle toward FLIGHT IDLE
If condition persists, ESP
Nacelle overheat warning on the ground:
GROUND IDLE, ESP
High TIT on ground:
GROUND IDLE
TD switches NULL
if condition persists, GROUND STOP
