ELP Notes Warnings and Cautions

Question 1

Abort Start

Answer 1

• 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

Question 2

Emergency Engine Shutdown on the Ground

Answer 2

Uses:

• Engine Fire
• Prop Strike or Chip Light
• Departure of prepared surface
• Other serious ground emergency

Question 3

Emergency Ground Egress

Answer 3

• 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)

Question 4

Abort

Answer 4

• Do not taxi into congestion after excessive braking
• Do not set parking break
• Give breaks time to cool

Question 5

Engine Failure Immediately after Takeoff

Answer 5

• Consider Immediate Ejection
• Do not sacrifice control while troubleshooting
• IDLE - Increased drag, OFF - reduce sink rate
• Loss of hydraulics = loss of gear and flaps

Question 6

Engine Failure During Flight

Answer 6

• 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

Question 7

Immediate Airstart (PMU Norm)

Answer 7

• 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

Question 8

Uncommanded Power Changes / Loss of Power / Prop Feather

Answer 8

• 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

Question 9

Compressor Stalls

Answer 9

• Defog-ON automatically selects high bleed inflow, alleviates back pressure
• With high rates of descent, any delay to shutdown engine prevents feathering

Question 10

Inadvertent Departure from Controlled Flight

Answer 10

• 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

Question 11

Fire in Flight

Answer 11

• 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

Question 12

Chip Detector Warning

Answer 12

• Higher Power settings may aggravate the condition

Question 13

Oil System Malfunction

Answer 13

• 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

Question 14

Low Fuel Pressure

Answer 14

• Fuel Px remains illuminated, high pressure fuel pump suction feeding, limited to 10 hours
• Do not reset boost pump circuit breaker

Question 15

OBOGS System Malfunction

Answer 15

• 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

Question 16

OBOGS Inoperative

Answer 16

• 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

Question 17

Eject

Answer 17

• 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

Question 18

Forced Landing

Answer 18

• 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

Question 19

PEL

Answer 19

• 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
