Single engine emergency shutdown
NOTES in conjunction

A
  1. VAR NR revert to manual mode automatically
  2. Before performing an in-flight single engine emergency shutdown determine if situation allows for OEI flight
  3. Make certain that the controls of the affected engine are selected and the collective is adjusted to maintain the normal engine within OEI limits

Q

What does FADEC-F stand for ?

What word is used under "the first F"

A

Fly the aircraft
(RAASH: Safe rotor speed Nr, Attitude wings level, Altitude L/O or climb, Speed for the situation, Heading away from danger towards landing area)
Alert the crew
Diagnose emergency
Execute procedure
Communicate (MAYDAY)
Fly the aircraft

Q

OEI flight conditions establish

Procedure when affected ENG tends to zero

A
  1. Maintain normal ENG withim OEI-limits
    (11 FLI MCP eller 12 FLI 2.5 min)
  2. Obtain Safe OEI flight conditions
    Safe level flight
  3. Continue EP

Q

OEI flight conditions establish

Procedure when affected ENG still delivers power

A
  1. Determine if situation allows for OEI flight (combined TQ below OEI limits - is it possible to use less power? Do we need above OEI limit power ?)
  2. If YES - affected engine to idle
  3. ## Continue EP if OEI-limits can be sustained
  4. If more power than OEI-limits is needed or OEI safe landing is not possible - LAND ASAP
    (If necessary re-establish power of affected engine prior to landing)

Q

Practice autorotation
Initiation

A

Minimum 700’
90 kts

Lower collective until engine and rotor RPM split

(and: VEMD lane 2 “IAS” field = 90 kts)

16
Q

Practice autorotation
after initiation until hover

A

Airspeed 75 KIAS
Heading +/- 5
Before 300 ft. ensure “steady state”
100 ft AGL 15-20 degresse pitch up
8-12 ft AGL 7 degreese pitch up
Raise collective to stop descent

steady state Rotor RPM (85-104) - Airspeed 75 - a/c trim - Glideslope

Can end in Go around og hover

17
Q

What are the to CAUTIONS in conjunction with autorotation ?

A
  1. Nr must be monitored during collective reduction to prevent overspeed
  2. Excessive nose up attitude during flare and prior to touch down ( 10º+ at or below 10ft ) may cause bumper strike
18
Q

What’s airspeeds during tail rotor malfunction ?

A

Min 70 KIAS until final then 40 (w. nose left)

19
Q

Single engine landing procedure

A
  1. Rotor speed - check max
  2. Bleed air heat. - Check off
  3. Airspeed - 65 KIAS
  4. Shallow approach
  5. 50’ @ 40 KIAS
  6. Max. 500 fpm descent rate
  7. Perform run on landing
20
Q

When an engine is shut down by the overspeed protection system - what happens to the normal engine ?

A

It is no longer protected against power turbine overspeed

21
Q

What CAUTION is in relation with ENG overspeed governor failure ?

A

If N2 RPM reaches 123.1% may result in engine overspeed trim = automatic shutdown

22
Q

SEF at low altitude - airspeeds for fly away

A

Initial: 30 KIAS
Fly away: 45 KIAS until 200’ AGL then 65 KIAS

23
Q

Anti-TQ malfunction
(tail rotor drive failure/fixed pitch)

What are the standards once established on final

A

70 KIAS until rate of closure is increasing then deccelerate to **40 KIAS +10/-5 **
no greater than 300 PFM rate of descent

24
Q

Anti-TQ malfunction
(tail rotor drive failure/fixed pitch)

____ crosswind component is advantageous

A

Left

25
Q

Anti-TQ malfunction
(tail rotor drive failure/fixed pitch)
What should be done if nose yaws right ?

A

Apply forward cyclic
(collective will accelerate right yaw)

26
Q

If in “OEI flight condition” - what airspeed would you climb at ?

A

Vy = 65 KIAS - best rate
Vx = 45 KIAS - best gradient

27
Q

When will the BAT TEMP light come on ?

A

Bat temp + 70 degrees
