Q

ORM 3-2-1

A

Do NOT descend below 2000’ AGL unless:

You are On Profile with the Runway in Sight and can safely Maneuver to Land

300’ AGL = Final Decision
200’ AGL= Gear Down
100’ AGL= On Centerline

Q

What are the signs of impending engine failure?

A
  1. Excessive Noise/Engine Vibrations
  2. Smoke/Fumes
  3. Chip light message on EICAS
  4. Oil pressure flucuations
  5. Loss of power & airspeed
  6. Rapid decay in N1, torque, and ITT
  7. Propeller moves towards feather due to loss of oil pressure

Q

PEL Procedure

A
  1. Turn towards nearest suitable field
  2. Climb in an attempt to get DEGA (climb at 140 KIAS)
  3. Clean up the aircraft
  4. Check the EICAS instruments for other signs of engine failure
  5. BIP
    * Boost Pump: As required
    * Ignition: As required
    * Plan to intercept ELP at some point (High Key, Low Key, or Eject)
  6. Determine the duty runway
  7. Deliver an ISPI report
  8. Reduce power to 4-6% torque no sooner than DEGA
  9. Lower landing gear no later High Key
  10. Report the Before Landing Checklist over ICS

Q

Basic Handling Emergency Rules

A
  1. Maintain aircraft control
  2. Analyze the situation and take proper action
  3. Land as soon as conditions permit/possible/practical
17
Q

How do you correct a low energy state in a PEL?

A

Use power to correct energy

DO NOT DELAY CONFIGURATION FOR LOW ENERGY STATE

18
Q

How do you correct a low energy state in a forced landing?

A

Delay configuration to correct energy

19
Q

Glide performance for ELP

A
  • 125 KIAS
  • 1350 - 1500 fpm descent rate
  • Glide ratio of 2NM for 1000’ of altitude
20
Q

What is the glide ratio for clean configuration?

A

2 NM for 1000’ of altitude

21
Q

Immediate Airstart (PMU NORM)

A
  1. PCL - OFF
  2. STARTER SWITCH - AUTO/RESET
  3. PCL - IDLE, ABOVE 13% N1
  4. ENGINE INSTRUMENTS - MONITOR ITT, N1, AND OIL PRESSURE

If airstart is unsuccessful:
5. PCL - OFF
6. FIREWALL SHUTOFF HANDLE - PULL
7. EXECUTE FORCED LANDING OR EJECT

If airstart is successful:
8. PCL - AS REQUIRED AFTER N1 REACHES IDLE RPM (APPROXIMATELY 67% N1)
9. PEL - EXECUTE

22
Q

Forced Landing

A
  1. AIRSPEED -125 KIAS PRIOR TO EXTENDING LANDING GEAR
  2. EMER LDG GR HANDLE - PULL (AS REQUIRED)
  3. AIRSPEED - 120 KIAS MINIMUM UNTIL INTERCEPTING FINAL; 110 KIAS MINIMUM ON FINAL
  4. FLAPS - AS REQUIRED
23
Q

Precautionary Emergency Landing (PEL)

A
  1. TURN TO NEAREST SUITABLE FIELD
  2. CLIMB OR ACCELERATE TO INTERCEPT ELP
  3. GEAR, FLAPS, SPEED BRAKE - UP
