EOP's - 3-1 to 3-3 Flashcards
DEFINITIONS
* Land Immediately
* Land as soon as practical
Land Immediately
Land on the nearest clear area where a safe normal landing can be performed.
Be prepared to enter autorotation during approach, if required.
Land as soon as practical
Landing site is at pilot’s discretion based on nature of problem and available landing areas.
Flight beyond nearest airport is not recommended.
- *POWER FAILURE - GENERAL**
- *(1st Sentence)**
A power failure may be caused by either an engine or drive system failure and will usually be indicated by the low RPM horn.
- *POWER FAILURE - GENERAL**
- *(2nd Sentence)**
An engine failure may be indicated by
- a change in noise level,
- nose left yaw,
- an oil pressure light,
- or decreasing engine RPM
POWER FAILURE - GENERAL
(3rd Sentence)
A drive system failure may be indicated by
- an unusual noise or vibration, nose right or left yaw,
- or decreasing rotor RPM while engine RPM is increasing
POWER FAILURE - GENERAL
(2nd Paragraph)
In case of power failure,
- immediately lower collective to enter autorotation and
- reduce air speed to power-off V(ne) or below.
CAUTION
(Power Failure - General / #1)
Aft cyclic is required when
collective is lowered at high air speed.
CAUTION
(Power Failure - General / #2)
Do not apply aft cyclic during touchdown or ground slide to prevent possible blade strike to tailcone.
1
POWER FAILURE
ABOVE 500 FEET AGL
Lower collective immediately to maintain rotor RPM
2
POWER FAILURE
ABOVE 500 FEET AGL
Establish a steady glide at approximately 70 KIAS.
(For maximum glide distance or minimum rate of descent, see page 3-3)
3
POWER FAILURE
ABOVE 500 FEET AGL
- Adjust collective to keep RPM between 97 and 108% or
- apply full down collective if light weight prevents attaining above 97%
4
POWER FAILURE
ABOVE 500 FEET AGL
- Select landing spot and
- if altitude permits, maneuver so landing will be into wind.
5
POWER FAILURE
ABOVE 500 FEET AGL
- A restart may be attempted
- at pilot’s discretion
- if sufficient time is available
- (See “Air Restart Procedure”, page 3-3)
6
POWER FAILURE
ABOVE 500 FEET AGL
- If unable to restart,
- turn necessary switches and fuel valve off
7
POWER FAILURE
ABOVE 500 FEET AGL
- At about 40 feet AGL,
- begin cyclic flare
- to reduce rate of descent and
- forward speed
8
POWER FAILURE
ABOVE 500 FEET AGL
- At about 8 feet AGL,
- apply forward cyclic to level ship and
- raise collective just before touchdown to cushion landing.
- Touch down in level attitude with nose straight ahead.
1
POWER FAILURE
BETWEEN 8 FEET AND 500 FEET AGL
- Lower collective immediately
- to maintain rotor RPM
2
POWER FAILURE
BETWEEN 8 FEET AND 500 FEET AGL
- Adjust collective to keep RPM between 97 and 108% or
- apply full down collective if light weight prevents attaining above 97%
3
POWER FAILURE
BETWEEN 8 FEET AND 500 FEET AGL
- Maintain airspeed until ground is approached,
- then begin cyclic flare to reduce rate of descent and forward speed.
4
POWER FAILURE
BETWEEN 8 FEET AND 500 FEET AGL
- At about 8 feet AGL,
- apply forward cyclic to level ship and
- raise collective just before touchdown to cushion landing.
- Touch down in level attitude with nose straight ahead.
1
POWER FAILURE
BELOW 8 FEET AGL
- Apply right pedal
- as required to prevent yawing.
2
POWER FAILURE
BELOW 8 FEET AGL
Allow helicopter to settle.
3
POWER FAILURE
BELOW 8 FEET AGL
- Raise collective
- just before touchdown
- to cushion landing
1

MAXIMUM GLIDE
DISTANCE CONFIGURATION
2nd Paragraph

- one nautical mile per 1300 feet AGL
1
MINIMUM RATE OF DESCENT
CONFIGURATION
Airspeed approximately 55 KIAS.
2
MINIMUM RATE OF DESCENT
CONFIGURATION
- Rotor RPM approximately 90%.
MINIMUM RATE OF DESCENT
CONFIGURATION
2nd Paragraph
- Minimum rate of descent is
- about 1350 feet per minute.
- Glide ration is about 4:1 or
- one nautical mile per 1500 feet AGL.
CAUTION
(Minimum Rate of Descent Configuration)
- Increase rotor RPM to 97% minimum or
- full down collective when autorotating below 500 feet AGL.
AIR RESTART PROCEDURE
CAUTION
- Do not attempt to restart
- if engine malfunction is suspected or
- before safe autorotation is established.
1
AIR RESTART PROCEDURE
CAUTION
Mixture - full rich.
2
AIR RESTART PROCEDURE
CAUTION
Throttle - closed, then cracked slightly.
3
AIR RESTART PROCEDURE
CAUTION
Actuate starter with left hand.
