OR
If LOW FUEL Warning light is on:
FUEL quantity indication… check
If both LOW FUEL Warning lights remain on:
LAND WITHIN 10 MINUTES
If one LOW FUEL warning light remains on:

Q

Max airspeed for floats

A

For inflation, lower than 80kn.

No limit if not inflated

17
Q

Single Engine Shutdown Acronym

A

Identify, Confirm, Select

18
Q

FADEC Minimum ENG TQ requirement

A

10%

19
Q

After landing with manual twistgrips, why is it necessary to reduce the collective at the same time.

A

To maintain an acceptable NR range

20
Q

LAND IMMEDIATELY

A

The urgency of landing is paramount. Primary consideration is to assure survival of occupants. Water, trees other unsafe as a last resort

21
Q

LAND AS SOON AS POSSIBLE (LAND ASAP)

A

Land without delay at the nearest adequate site (open field) at which a safe approach and landing can be made.

22
Q

LAND AS SOON AS PRACTICABLE

A

The landing site and duration of flight are at the discretion of the pilot. Extended flight beyond nearest approved landing area where appropriate assistance can be expected is not recommended.

23
Q

FADEC FAIL (SYSTEM 1) or FADEC FAIL (SYSTEM 2)

A
  1. Collective Lever… Adjust as necessary to maintain N(RO) within normal range
  2. Affected engine… Identify by small collective changes
  3. Respective TWIST GRIP… Adjust slowly to set 80% (+ or - 2%) N(1) [Gas generator] on the affected engine (TWIST GRIP caution my come on). Simultaneously adjust collective to maintain engine within limits
    After Landing:
  4. Respective TWIST GRIP… Reduce, before lowering the collective pitch lever to full down position (to keep N(2) [power turbine speed] /N(RO) [rotor speed] within limits
24
Q

SINGLE ENGINE FAILURE - FLIGHT

A
  1. OEI flight condition… establish
  2. Affected engine… identify
  3. Single engine emergency shutdown… perform
  4. LAND AS SOON AS PRACTICABLE
  5. Single engine landing… Perform checklist
25
Q

SINGLE ENGINE FAILURE - HIGE

A
  1. Collective lever… Adjust to maintain rotor RPM
  2. Landing attitude… Establish
  3. Collective lever… Raise as necessary to stop descent and cushion landing
    After landing
  4. Affected engine… Identify
  5. Single engine emergency shutdown… Perform
26
Q

SINGLE ENGINE FAILURE - HOGE

A
  1. Airspeed… Increase if possible
  2. Collective lever… Adjust to maintain rotor RPM
    If forced landing required:
  3. Landing attitude… Establish
  4. Collective lever… Raise as necessary to stop descent and cushion landing
    After landing:
  5. Affected engine… Identify
  6. Single engine emergency shutdown… Perform
27
Q

TAIL ROTOR DRIVE FAILURE - FWD FLIGHT

If the nose direction changes from left to right at airspeeds higher than 40kn

A
  1. Collective lever… Reduce to obtain minimum sideslip angle
  2. Airspeed… Maintain 70 KIAS or higher
    If the nose direction changes from left to right at airspeeds higher than 40kn:
  3. Airspeed… Increase (Nose down)
  4. Approach.. Abort, climb to sufficient height for autorotation
  5. Autorotation… Perform
28
Q

SINGLE ENGINE FAILURE - TAKEOFF

A
  1. Collective lever… Adjust to maintain rotor RPM
  2. Landing attitude… Establish
  3. Collective lever… Raise as necessary to stop descent and cushion landing
    After landing:
  4. Affected engine… Identify
  5. Single engine emergency shutdown… Perform
29
Q

On ground
1. BAT MSTR sw… OFF
2. Engines… Shutdown
In Flight
1. BAT MSTR sw… OFF
2. LAND ASAP

30
Q

Warning lights are accompanied by what sound?

A

Gong
