ELP Notes Warnings and Cautions Flashcards
1
Q
Abort Start
A
- Note and report over-temperature
- Placement of PCL dictates abort method
- External Power and PMU aborts, do not attempt restart
- Repeated PMU aborts indicative of engine malfunction
- Weak battery, high OAT, high pre-ITT, high DA, tailwind may cause PMU abort (rate of N, ITT indicative of hot or hung start)
- Battery start aborted, connect power and motor run
2
Q
Emergency Engine Shutdown on the Ground
A
Uses:
- Engine Fire
- Prop Strike or Chip Light
- Departure of prepared surface
- Other serious ground emergency
3
Q
Emergency Ground Egress
A
- 0/0 Ejection
- Inadvertent ejection (ISS or Seat Safety Pin)
- CFS Failure, ejection only option, ensure strapped in
- PPE on for CFS
- Both CFS handles must be pulled
- Hoses will pull free while vacating cockpit (leg restraints, quick release)
4
Q
Abort
A
- Do not taxi into congestion after excessive braking
- Do not set parking break
- Give breaks time to cool
5
Q
Engine Failure Immediately after Takeoff
A
- Consider Immediate Ejection
- Do not sacrifice control while troubleshooting
- IDLE - Increased drag, OFF - reduce sink rate
- Loss of hydraulics = loss of gear and flaps
6
Q
Engine Failure During Flight
A
- Crosscheck N1 for immediate airstart
- Power changes / loss / stalls / prop feather - Appropriate Procedeure
- Prop will not feather unless PCL is OFF
- Do not delay turn to ELP
- Do not delay decision to eject below 2000 AGL
- Airstart not recommended below 2000 AGL
7
Q
Immediate Airstart (PMU Norm)
A
- Attempts outside envelope may be unsuccessful or result in over-temperature
- Do not delay ejection below 2000 AGL
- PCL - OFF for feathering, proper starter, ignition, boost pump and PMU operation
- PCL-OFF or fuel may be prematurely introduced
- PCL above idle too quickly, increase in FF, severe ITT overtemp
- N1 rise in 5 seconds discontinue
- ITT rise in 10 seconds, abort the start
- Note duration of flight with BOOST pump on
- If generator wont reset, verify starter switch in Norm
- Starter will drain batt. in 10 minutes in MANUAL
8
Q
Uncommanded Power Changes / Loss of Power / Prop Feather
A
- Midway physical PCL angle
- Above idle best chance
- Mid range PCL minimizes over-torque/temp with PMU off
- ITT limits exceeded with ITT > 820 and PMU off
- No ground Idle, increased landing distance
- Constant airspeed and torque, RPM stable below 40% and no upward change for 3 seconds
- Np red X’s, PMU norm then OFF
- Prop feather recovery 15-20 seconds
- Rate of Descent > 1500 increase torque to 131% or PCL-OFF
- Consider moving PCL through full range to determine power available
- Consider leaving the engine operating at mid-range
- With breaker pulled and PMU-OFF prop will feather slower, glide performance reduced
9
Q
Compressor Stalls
A
- Defog-ON automatically selects high bleed inflow, alleviates back pressure
- With high rates of descent, any delay to shutdown engine prevents feathering
10
Q
Inadvertent Departure from Controlled Flight
A
- Aft of Neutral may delay recovery
- Cycling of controls or anti-spin prematurely can aggravate motion and delay recovery
- Ejection min is 6000 AGL
- Power-On and Inverted spins result in high loads on engine, land ASAP
11
Q
Fire in Flight
A
- Confirmation:
- Smoke
- Flames
- Engine vibration
- Unusual sounds
- High ITT
- Fluctuating oil pressure, temperature or hydraulic pressure
- Do not shut down engine for unconfirmed fire
- Bleed air leak, reduce PCL toward IDLE
- Cannot be confirmed FWS may be at fault
12
Q
Chip Detector Warning
A
- Higher Power settings may aggravate the condition
13
Q
Oil System Malfunction
A
- Use for:
- Red Oil PX
- Amber Oil Px
- Oil pressure fluctuations
- Temp. out of limits
- < 5psi check OIL TRX breaker (batt bus)
- Single momentary illumination may not signal malfunction
- Both Red and Amber Px with normal pressure indicates SCU failure
- High power settings may aggravate the condition
14
Q
Low Fuel Pressure
A
- Fuel Px remains illuminated, high pressure fuel pump suction feeding, limited to 10 hours
- Do not reset boost pump circuit breaker
15
Q
OBOGS System Malfunction
A
- No batt, no OBOGS
- Low bleed air, may indicate warning
- Hypoxia above 10,000’
- Increased Pressure, breath slower, hyperventilation
- OBOGS Fail with both supply levers off and engine running
16
Q
OBOGS Inoperative
A
- Hypoxia, land ASAP
- Emergency descent below 10,000’ if OBOGS inop.
- Batt fails, no OBOGS
- Hyperventilation, breath slower and less deep
- High-pressure air makes comms difficult
- Emergency oxygen cannot be shutoff
- When disconnecting main oxygen hose, avoid disconnecting COMM cable, improves breathing
17
Q
Eject
A
- Pull towards abdomen, elbows in
- Visor down, Mask and gloves on
- 8000’ MSL over terrain, MOR handle
- Low speed - one or both risers may remain together, manually separate
18
Q
Forced Landing
A
- Distance Increase with Prop feather
- Unprepared surface may cause structural damage (CFS affected)
- Engine shutdown will disable bleed air system (icing/fogging)
- Ejection recommended if suitable landing area not available
- Induced yaw with known engine malfunction may result in oil leakage on windshield
- Unprepared surface, do not extend landing gear, flaps will not be available
- Safe gear indications will have red and green lights
- TO or LDG will extend flaps to position if gear is used and battery is available
- LG or flap retraction not possible with emergency system
- NWS unavailable with inoperative engine
- Activating ELT higher may aid in rescue/recovery
19
Q
PEL
A
- Engine fail transition to forced landing
- Increase torque for rate of descent >1500 or PCL-OFF
- Once on Profile if excessive vibrations, PCL-OFF
- Engine shutdown, no bleed air possible (fogging/icing)
- Induced yaw could lead to oil leakage on windshield
- Do not set boost pump on for oil system, chip light or FOD malfunctions (Relight )
- Uncontrollable high power, must shut engine down once landing assured
