EP (Indications, Actions, Considerations) Flashcards
Abort Start (Indications)
- BAT BUS light illuminates
- ST READY extinguishes OR PCL moved before 60% N1
- No start: no ITT rise w/in 10 sec of fuel flow indications
- Hung start: Normal N1 increase is halted (normally around 13-20%)
- Hot start: ITT rate of increase appears likely to exceed 1,000*C
Abort Start (Actions)
- ABORT START PROCEDURE
- Place PCL to OFF or STARTER switch to AUTO/RESET aborts start immediately
- If external power was connected, do not attempt further restarts
- If external power was not used, connect external power, run motoring procedure, and try the start again
Abort Start (Considerations)
- Common hot start/PMU abort causes:
- Low voltage (< 23.5 V)
- Hot WX, IOAT > 80*C
- Cold WX, IOAT < 0*C
- Aircraft parked w/ tailwind
- If ST READY goes out, start must be manually aborted by:
- PCL OFF
- Subsequent start attempts allowed, but not advisable unless cause of abnormal start is determined
- Notify maintenance
- Starter duty cycles
- Technique: consider ext power if ITT > 80C, ITT + IOAT > 200C, batt voltage < 24.5, or strong tailwind
Fire Warning on the Ground (Indications)
- Fire Light and Master Warning Light w/ aural tone
- Visual smoke or fire
- Engine indications (eg High ITT, fluctuating fuel flow)
- Notification from exterior sources (ground crew, tower)
Fire Warning on the Ground (Actions)
- EMERGENCY ENGINE SHUTDOWN ON THE GROUND
- EMERGENCY GROUND EGRESS
Fire Warning on the Ground (Considerations)
- Treat any fire indication as confirmed fire
- Contact ground to advise and expedite emergency response
- Egress:
- 0/0 seat
- check for fire outside before egress
- ISS SOLO
- Can egress right w/ CFS
- Ensure FCP knows what to do before BAT off/comm out
Emergency Engine Shutdown (Indications)
- Engine fire
- Prop strike
- CHIP light
- Departing a prepared surface
- Other serious ground emergency
- Fuel flow > 800 pph (fuel nozzle tip fracture)
Emergency Engine Shutdown (Actions)
- EMERGENCY ENGINE SHUTDOWN ON THE GROUND
- EMERGENCY GROUND EGRESS (as required)
Emergency Engine Shutdown (Considerations)
- If emergency egress is not needed, complete normal checklists
- If emergency egress is required, placing ISS-SOLO and PIN IN are critical first steps
- Communication will be unavailable with BAT OFF
- Brief radio call to Ground or Tower will help expedite problem resolution…provide aircraft location
- Tell intentions to other crewmember (EGRESS x3 and side) before BAT OFF
Emergency Ground Egress (Indications)
- Fire smoke, fluid leak, or any other situation that requires immediate evacuation of the aircraft after coming to a full stop
Emergency Ground Egress (Actions)
- EMERGENCY GROUND EGRESS
Emergency Ground Egress (Considerations)
- Fully stop before egressing
- If engulfed in flames or collision imminent, consider ejecting
- CFS can be used to egress right
- Ensure mask up/visor down prior to blowing CFS
- Comm unavailable when BAT OFF
- Brief radio call to Ground or Tower will help expedite problem resolution…provide aircraft location
- Discuss actions/expectations with other crewmember
- Ensure PIN IN. Do not rush during egress
- ISS-SOLO, PIN IN, then 2-1-2-2
- Oxygen hose, emergency O2 hose, comm leads, and G-suit will pull free. Stand up with authority
- Exit 45* aft of aircraft, meet 300 feet from aircraft
- Watch for emergency vehicles
