What are the indications for a Fire engine 1/2?
2nd alternative, twist grip affected engine - rotate slowly to idle, check indications.
the second alternative enables the crew to use the affected engine for landing if neccesary, be prepared for engine failure. Monitor N1, TOT, TRQ, oil pressure and temperature of affected engine closely. If the parameters fluctuate or their limits are exceeded perform single engine emergency shutdown immediately.
What is recommended for engine chip landing?
1. Collective lever – Reduce to obtain minimum sideslip angle
2. Airspeed – Maintain 70 KIAS or higher 3. Suitable landing area – Select
NOTE D Landing surface should be hard (e.g. concrete, asphalt) and flat.
D Left crosswind is advantageous
4. Shallow approach with nose left – Perform
If the airspeed can be reduced below 40 kts with the nose still pointing to the left:
5. Airspeed – Reduce close to the ground until nose is aligned with the 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 to sufficient height for autorotation
NOTE Headwind is advantageous
7. Autorotation – Perform
What is the procedure for tail rotor drive/fixed pitch failure?
1. Collective lever – Raise as necessary to maintain N2 and NRO within limits
2. VAR NR system NORM/MAN sw – Check MAN
3. N2 TRIM sw – Try to trim NRO to 101% with matched torque
If step 3. is not possible:
4. Affected engine – Identify
5. Twist grip (affected engine) – Rotate towards IDLE until N2 and NRO stabilize in normal range and FLI needles match
6. LAND AS SOON AS PRACTICABLE
What is the procedure for engine overspeed - governor failure?
CACRACASL
What is Single engine failure OGE fly-away
Conditions/Indications
– ROTOR RPM warning light may come on – VAR NR caution indication may come on – ENG SPLIT caution indications may come on – NRO and both N2 increase
Affected engine: – Torque, N1 and TOT increase
Normal engine: – Torque and TOT may decrease
What is engine overspeed - governor failure?
At approx. 100 ft AGL
flare attitude - establish (approx 15 to 20) to reduce forward speed and rate of descent, control Nro
At approx. 8 - 12 ft AGL
flare attitude - reduce to approx 7
heading - maintain
collective lever - Raise to stop descent and cushion landing
what is the approach in autorotation?
1. OEI flight condition – Establish
2. Bleed air consumers – Off
3. VAR NR system NORM/MAN pb – Check MAN
4. Affected engine – Identify
5. N2 TRIM sw – Compensate N2/NRO drop and try to match torque If torque match is not possible:
6. Twist grip (affected engine) – Release stop plate and rotate towards FLIGHT until N2 and NRO stabilize in normal range and FLI needles match 7. LAND AS SOON AS PRACTICABLE If no residual torque (affected engine) is available:
8. Single engine emergency shutdown – Perform
What is the procedure for engine underspeed - governor failure?
Power - reduce
land as soon as practicable
if indications are below 1.0 bar
land immediately
What is Transmission oil pressure?
OBVNTLS
What is Engine underspeed - governor failure?
XMSN OIL P warning
What is a low oil pressure below 1 bar?
Approach and landing recommendations
Make normal power changes to allow the normal engine to operate within limits. If more collective input is needed, adjust power of the affected engine using twist grip. .
After landing: Rotate twist grip (affected engine) towards IDLE before lowering the collective lever to full-down position (maintain NRO and N2 within limits).
CAUTION N2 RPM OVER 123.1% MAY RESULT IN AN ENGINE OVERSPEED TRIP (AUTOMATIC SHUTDOWN).
What is the recommended approach and landing for governor failure?
Collective lever - reduce to maintain Nro within limits
Airspeed - reduce to 90 KIAS
Double engine emergency shutdown - perform
Battery mstr sw - Off
What is a max range autorotation?
1. Collective lever – Adjust to maintain rotor RPM
2. Airspeed – Increase if possible
F TRANSITION TO OEI - FLIGHT
3. Collective lever – Adjust to OEI-limits or below
4. Rotor speed – Trim to maximum
5. Airspeed – Gain, 65 KIAS (VY) 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
What is the procedure for single engine failure in hover OGE - transition to OEI flight?
