OEI Ops Flashcards
What does “OEI Flight conditions - Establish” mean?
Any speed between 40-110kts that is less than 11FLI (OEI MCP)
Faster flight requires more PWR
Explain the CANCA process for single engine fail in flight?
C - Call indication (ENG FAIL CAUTION ENGINE 2)
A - Boldface —> Safe heigh, HDG, Speed
N - Landing area? RWY vs taxiway vs field
C - “NFP make a PAN call for landing at: “
A - Pre landing checks, non boldface items, PWP and single engine landing checklist
Explain how OEI influences the PWP
Consider weight and OEI HOGE/HIGE time
Don’t just brief a CAT4 normal angle profile approach, consider need for running LDG or shallow approach if time critical (likely not is OEI)
What is an example of the single engine approach “plan” brief?
We have HIGE OEI 2 min, wind is 10kts down the RWY, this will be a shallow profile approach to the 1000ft markers, NFP calls powers above OEI MCP
Double ENG EMRG Shutdown on the ground
Both main sw - OFF
Both FADEC - OFF
Both Prime Pumps - OFF
BAT MASR - OFF
If still running
Twist Grips - Off
What indications should you expect for a single engine fail in flight?
- Yaw to L
- Nr droop if at high PWR
- CAD 4x Cautions (ENG FAIL, ENG OIL P, FUEL PRESS, GEN DISCON)
- TQ, N2 and N1 trending or already reading 0%
If you are required to complete a steep approach when OEI, how does that effect you RoD?
You should not descend faster than 300ft/min
You are departing and see ENG fail, you are not yet at 150ft or 65kts and have not called flyaway, what are your actions?
“Engine failure, aborting”
Lower collective to capture Nr
Asses height/speed, set flare to decel
Set landing attitude
Collective to cushion approach
Land the aircraft
Single ENG EMRG shutdown on ground
What does “flyaway” mean?
The flyaway call is made when the aircraft reaches a safe single engine performance envelope, typically at 723 this is 65kts 150ftAGL
Advanced considerations include height loss, weight, wind, landing area available and obstacles
What does “committed” mean?
The aircraft can no longer go around with its current weight/plan (typically called when slowing below 65KIAS)
You are departing RWY 03 about to turn crosswind and see “ENG FAIL”, what are your actions?
CANCA for ENG FAIL
Simultaneously:
- Collective to capture RRPM if req
- FLI within limits
Maintain 65KIAS
Once clear of obstacles
FLI less than 11
Single engine shutdown
Explain single engine failure prior to committed
Similar to HOGE ENG fail
Bang
“Engine failure, going around”
Simultaneously set:
- 15ND
- 30 Sec PWR
At 40kts set 65kts attitude
Once clear of obstacles set 2 min PWR
Explain your actions for a single engine failure after committed
Bang
Collective to capture RRPM
RoD not above 300f/min
Assess height/speed for aspect
OEI landing
What are your actions for a single engine failure HIGE?
Collective to capture Nr
Landing attitude establish (flare/flatten out the aircraft)
Gently lower the collective to establish descent
Land the aircraft
Single engine EMRG Shutdown
What are your actions for a single engine failure HOGE below height loss?
When below height loss you are committed to the ground
Collective to capture Nr
Landing attitude establish (flare/flatten out the aircraft)
Gently lower the collective to establish descent
Land the aircraft
Single engine EMRG Shutdown
Largely the same as IGE, will be descending vertically for longer
If you have an engine failure, which way will the nose move?
Left
How can 11FLI be easily recognised on the FLI?
Striped yellow bar (biggest one)
Explain your actions for an OEI shallow airfield approach
65kts, 700ft
Shallow aspect
“Commencing the approach”
Power (2-300ft/min RoD)
Aim point, aspect, airspeed
At 100ft:
Set flare attitude
Skids straight
Collective for aim point
You are HOGE above height loss and experience an engine failure, what are our actions?
Above height loss means your are flyaway
Simultaneously:
- Set 20ºND
- Regain RRPM if req
- Set OEI 30sec PWR
Maintain the attitude
At 40kts set 65kts attitude
At a safe alt, set FLI 2 min of MCP as req
Single engine EMRG shutdown
You should always be hovering into wind
Engine overspeed - driveshaft fail actions
- OEI flight condition - Establish
- Affected engine - Identify
- Single Engine EMRG shutdown - Perform:
- ENG MAIN sw (confirm correct ENG) - IDLE, check indications, then OFF
Engine oil temp high actions
- Airspeed - Increase if possible
If ENG oil temp remains above limit
2. OEI flight conditions - Establish
3. Affected engine - Identify
4. Engine main sw - Idle
5. Oil temp indicator - Monitor
Oil temp still above limits
6. Single engine EMRG Shutdown- Perform
- ENG MAIN sw (confirm correct ENG) - IDLE, check indications, then OFF
Engine oil press low actions
- Check the indication
- OEI flight conditions - Establish
- Affected engine - Identify
- Single engine EMRG shutdown
- ENG MAIN sw (confirm correct ENG) - IDLE, check indications, then OFF
Generator overheat
Engine chip fuzz burn actions
