Answer 12

Landing site and duration of flight are at discretion of the pilot, extended flight not recommended

Question 13

Land as soon as possible

Answer 13

Land without delay at the nearest adequate site which a safe approach and landing can be made

Question 14

Land Immediately

Answer 14

Urgency of landing is paramount, survival of occupants should be primary consideration

Question 15

Engine 1 or Engine 2 fire in-flight

Answer 15

1) OEI flight conditions: ESTABLISH
2) Airspeed: Reduce if exceeding 100kts
3) Fire SW: Rais guard, press
4) BOT1/BOT 2 pb: Press, Bot 1 activated; EXT indicator light comes on
5) Clock stopwatch: Start (after bot EXT light goes off)
6) Affected engine: Identify
7) Single engine emergency shutdown: Perform
8) Passengers: Alert
9) LAND AS SOON AS POSSIBLE

If fire warning is still on after 1 min:
10) BOT 1/BOT 2 pb: Press, Bot 2 activated
-EXT indicator light comes on
11) Land immediately

Question 16

Single engine failure-Hover OGE

Answer 16

1) Collective lever: Adjust to maintain rotor RPM
2) Airspeed: Increase if possible

-FORCED LANDING
3) Landing attitude: Establish
4) Collective Lever: Raise to control descent and cushion landing

-AFTER LANDING
5) Affected engine: Identify
6) Single engine emergency shutdown: Perform

-TRANSITION TO OEI-FLIGHT
3) Collective Lever- Adjust to OEI limits or below
4) Rotor speed: Trim to max
5) Airspeed: Gain 65 KIAS

-AFTER REACHING SAFE ALTITUDE:
6)Collective lever- Reduce to OEI MCP or below
7) Affected engine: Identify
8) Single engine emergency shutdown: Perform
9) LAND AS SOON AS PRACTICABLE

Question 17

Single engine failure- Flight

Answer 17

1) OEI flight condition: Establish
2) Rotor speed: Trim to max
3) Affected engine: Identify
4) Single Engine emergency shutdown: Perform
5) LAND AS SOON AS PRACTICABLE

Question 18

Engine overspeed- governor failure

Answer 18

1) Collective lever: Raise to maintain N2 & NRO limits
2) VAR NR system NORM/MAN sw- Check Manual
3)N2 trim sw: Try to trim NRO to 101%

If step 3 is not possible:
4) Affected engine: identify
5) Twist grip (affected engine): Rotate toward IDLE until N2 and NRO stabilize in normal range and FLI needles match
6) LAND AS SOON AS PRACTICABLE

Question 19

Single engine emergency shutdown

Answer 19

1) Twist grip: Rotate slowly to IDLE, check indications, then off
2) Rotor speed: Trim to max
3) BLD HTG EMER/NORM sw- EMER
4) BLD HTG rheostat- ON

Question 20

Autorotation

Answer 20

1) Collective Lever- Reduce to maintain NRO within limits
2) Airspeed: 75 KIAS
3) Double engine emergency shutdown: Perform
AT APPROXIMATELY 100ft AGL
4) Flare attitude- Establish to reduce forward speed and rate of descent; control NRO
AT 8-12ft AGL
5) Flare attitude: Reduce to approx 7 degrees
6) Heading- Maintain
7) Collective Lever- Raise to stop descent and cushion landing
8) BAT MSTR sw- OFF

Question 21

Tail Rotor Drive Failure/ Fixed-pitch Tail Rotor Control -Forward Flight

Answer 21

1) Collective Lever- Reduce to obtain minimum sideslip angle
2)Airspeed- 70 KIAS or higher
3) Suitable landing area- Select
4) Shallow approach with nose left- Perform

IF AIRSPEED CAN BE REDUCED BELOW 40 KTS WITH NOSE STILL POINTING LEFT
5) Airspeed- Reduce close to ground until nose is in flight direction
6) Landing- Perform

IF THE NOSE DIRECTION CHANGES FROM LEFT TO RIGHT AT AIRSPEEDS HIGHER THAN 40 KTS
5) Airspeed- increase
6) Approach- Abort, climb for autorotation
7) Autorotation- Perform
