FLIGHT / Emergency handle Flashcards
Single engine emergency shutdown
NOTES in conjunction
- VAR NR revert to manual mode automatically
- Before performing an in-flight single engine emergency shutdown determine if situation allows for OEI flight
- Make certain that the controls of the affected engine are selected and the collective is adjusted to maintain the normal engine within OEI limits
What’s the procedure for single engine emergency shutdown ?
blod face
- Twist grip (affected engine) - Rotate slowly to idle, check indication, then to OFF
- Rotor speed - Trim to maximum
What’s the procedure for double engine emergency shutdown

3. BAT MSTR sw - OFF
In flight
1. Both twist grips - OFF
2. Both EMER OFF sw - Press
Caution indication - ENG CHIPON GROUND / IN FLIGHT
Bold face
On ground
1. Affected engine - Identify
2. Single engine emergency shutdown - PErform
In flight
1. OEI flight conditions - Establish
2. Affected engine - Identify
3. Option - Single engine emergency shutdown
Option - Twist grip (affected engine) - Rotate slowly to idle, check indications
CAUTION: ENG OIL P
Bold face

- Affected engine - Identify
- Single engine emergency shutdown - Perform
(Land as soon as practicable)
Engine oil temp. high
Bold face
- OEI flight conditions - Establish
- Affected engine - Identify
- Twist grip (affected engine) - Adjust to 20-30% TQ (twist grip caution come on)
- Oil temperature indicator (affected engine) - Monitor
If engine oil temperature still remains above limits:
6. Single engine emergency shutdown - Perform
What’s the boldface in conjunction with
Warning light - LOW FUEL
Land within 10 minutes
Expect single engine failure
Warning light:
XMSN oil pressure
Bold face
1 below 1
1. Power reduce
2. Land as soon as prac.
2 below 1
1. Land immediately
Caution indication:
XMSN oil temperature
Bold face
- XMNS oil temperature and oil pressure - Check indication
Within limits
2. Land as soon as practicable
Above limits
2. Power - Reduce as much as possible
Remains above limits
3. Land as soon as possible
What does FADEC-F stand for ?
What word is used under "the first F"
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
Which two situation is there for
“OEI flight conditions - Establish”
- PWR affected ENG tends to zero
- Affected ENG still delivers PWR
OEI flight conditions establish
Procedure when affected ENG tends to zero
- Maintain normal ENG withim OEI-limits
(11 FLI MCP eller 12 FLI 2.5 min) - Obtain Safe OEI flight conditions
Safe level flight - Continue EP
OEI flight conditions establish
Procedure when affected ENG still delivers power
- 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 ?)
- If YES - affected engine to idle
- ## Continue EP if OEI-limits can be sustained
- 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)
Inadvertent IMC
Announce
Attitude / wings level
Heading / maintain
Torque /
Trim
Airspeed /
Altitude / climb to 3500 MSL
Transponder 7700
Contact on guard 121.5 / 243.0
Practice autorotation
Initiation
Minimum 700’
90 kts
Lower collective until engine and rotor RPM split
(and: VEMD lane 2 “IAS” field = 90 kts)
Practice autorotation
after initiation until hover
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
What are the to CAUTIONS in conjunction with autorotation ?
- Nr must be monitored during collective reduction to prevent overspeed
- Excessive nose up attitude during flare and prior to touch down ( 10º+ at or below 10ft ) may cause bumper strike
What’s airspeeds during tail rotor malfunction ?
Min 70 KIAS until final then 40 (w. nose left)
Single engine landing procedure
- Rotor speed - check max
- Bleed air heat. - Check off
- Airspeed - 65 KIAS
- Shallow approach
- 50’ @ 40 KIAS
- Max. 500 fpm descent rate
- Perform run on landing
When an engine is shut down by the overspeed protection system - what happens to the normal engine ?
It is no longer protected against power turbine overspeed
What CAUTION is in relation with ENG overspeed governor failure ?
If N2 RPM reaches 123.1% may result in engine overspeed trim = automatic shutdown
SEF at low altitude - airspeeds for fly away
Initial: 30 KIAS
Fly away: 45 KIAS until 200’ AGL then 65 KIAS
Anti-TQ malfunction
(tail rotor drive failure/fixed pitch)
What are the standards once established on final
70 KIAS until rate of closure is increasing then deccelerate to **40 KIAS +10/-5 **
no greater than 300 PFM rate of descent
Anti-TQ malfunction
(tail rotor drive failure/fixed pitch)
____ crosswind component is advantageous
Left
Anti-TQ malfunction
(tail rotor drive failure/fixed pitch)
What should be done if nose yaws right ?
Apply forward cyclic
(collective will accelerate right yaw)
If in “OEI flight condition” - what airspeed would you climb at ?
Vy = 65 KIAS - best rate
Vx = 45 KIAS - best gradient
When will the BAT TEMP light come on ?
Bat temp + 70 degrees
