Failure management model
Fly the aircraft
Confirm the failure
Short term plan
Take action
-memory items
-MFDU
-QRH
-CBs
- checklists
Long term plan
- AOM
- MEL
- status aircraft, fuel, weather etc
Decide return continue or divert
Inform
- ATC
- cabin
- pax
- company
Engine fire on ground
Set park brake
Assess problem
Assess if evacuation is likely
Make PA
Command “TAKE ACTION”
During 45sec gather info from ATC
Complete MFDU
If required “TAKE ACTION ON GROUND EMERGENCY EVACUATION”
Make appropriate PA
What is a NITS brief and when is it used
A NITS brief is an ‘emergency landing briefing’ and must be conducted by the captain before preparing the cabin for an emergency landing.
N - nature of emergency
I - Intended plan of action
T - time available
S - special instructions
-speed of evac
- possibility of structural damage/fire
- possibility of unusual aircraft attitudes
- high surface winds
- ground/water conditions
Severe turbulence actions
- set speed to 250kt / M .65
- seat belt sign ON
- ignition to AUTO or CONT
- engine anti-icing as required
when at speed
- disconnect ATS
Pilot incapacitation actions
- set AP on
- call cabin crew to flight deck
- check incapacitated pilot doesn’t interfere with the controls
- lock harness and push seat back
- most suitable airport and approach
Engine failure at flight levels
Drift down actions
- select PROF
-confirm engine out at FMS (MCT selected automatically) - lower FMP alt to predicted OEI ceiling and pull ALT to arm drift down
- the aircraft will decelerate level and descend at green dot
- alert atc “require level …..”
- perform engine failure and single engine procedure
For engine fire action MFDU immediate and drift down actions in 45 secs
Wind shear on take-off actions
(with wind shear recovery available)
- aggressively select and verify full throttle thrust (do not hold at firewall)
- follow FD guidance
-respect stick shaker- - retract gear and flap as normal
Note:
- at 1500ft or with 1800fpm for at least 5 seconds system will transition to recovery mode.
- ATS reverts to TOGA upon exit of recovery mode
EGPWS “PULL UP” or “TERRAIN” warning actions
IMMEDIATELY AND SIMULTANEOUSLY
- pull TOGA triggers
- AP/AT disconnect
- thrust levers fully forward
- pitch to 20deg or higher
-disregard FD commands-
With terrain clearance assured
- reduce thrust to TOGA or GA thrust
- ATS on
- set FMP alt
Stall recovery actions - CURTS
Click - AP
Click - AT
Unload - wing
Roll - wings level
Thrust - apply as required
Stabilise - to level flight
TCAS RA
Disengage AP
Manually follow the PFD cues
When “clear of conflict”
Manually return to assigned level
Select AP on
AFCAS driftdown procedure
Of obstacle clearance no factor:
- Confirm engine out at FMS
- Lower the FMP alt to predicted SE ceiling
- Select V/S and use normal descent schedule
- Perfom engine failure and SE procedure
If obstacle clearance is limiting:
- Confirm engine out
- Lower FMP alt to predicted SE ceiling
- The aircraft will decelerate level. Driftdown commenced upon reaching green dot.
- Perform engine failure and SE procedure
Note pulling ALT will result in a LVLCH DES mode with the live engine reduced to LL thrust.
PROF driftdown procedure
- Confirm engine out at FMS
- Lower FMP altitude to predicted SE ceiling and pull ALT knob at FMP to arm driftdown
- Aircraft will decelerate level. Driftdown commences upon reaching greed dot.
- Perform engine failure and SE procedure.
Wind shear on approach actions
(with wind shear recovery available)
- pull TOGA triggers and verify full throttle thrust (do not hold at firewall)
- follow FD guidance
-respect stick shaker- - retract gear and flap when sustained positive climb is achieved
Note:
- at 1500ft or with 1800fpm for at least 5 seconds system will transition to recovery mode.
- ATS reverts to TOGA upon exit of recovery mode
