What is the procedure for descending if cabin altitude is uncontrollable?
Thrust levers to idle, extend speedbrakes, descend at Vmo/Mmo.
These steps help to safely reduce altitude.
What should be done with the RAM AIR TURBINE switch during a dual engine failure?
Push and hold 1 for sec.
Activating the RAM AIR TURBINE provides emergency power.
In case of engine limit exceedance, what should be done with the thrust lever (affected side)?
Retard until ENG LIMIT EXCEED message blanks or thrust lever is at idle.
This action helps to mitigate engine stress.
What is the procedure for addressing engine surge?
A/T ARM switch (affected side) OFF, Thrust lever (affected side) Retard until ENG SURGE message blanks.
Managing engine surge is critical for engine safety.
What should be done with the A/T ARM switch during an engine fire in flight?
A/T ARM switch (affected side) OFF.
This step helps to control engine power during an emergency.
What is the final action if the FIRE ENG message stays shown after pulling the engine fire switch?
Confirm pulling the engine fire switch (affected side).
This ensures that the engine is shut down in an emergency.
What should be done with the STAB cutout switch (both)?
CUTOUT.
This action is necessary to manage the stabilizer control in critical conditions.
True or False: The thrust lever (affected side) should be set to idle during an engine fire.
True
This is part of the standard emergency procedure.
What should be advised to the cabin in case of evacuation?
Advise the cabin to evacuate
Important for ensuring passenger safety during emergencies
What is the first action to take if an engine or APU fire is observed?
Related fire switch CUTOFF
Critical step in fire management procedures
What should be done with the OUTFLOW VALVE switches during evacuation?
Set both OUTFLOW VALVE MANUAL switches to MAN
Ensures proper cabin pressure management
What should be established when below FL 290 in oceanic airspace?
Maintain 150m (500ft) vertical offset when able
Ensures safe separation from other aircraft
What is the recommended action for transponder settings in emergencies?
Set transponder to 7700
Indicates emergency situation to ATC
Fill in the blank: When in oceanic airspace, you must establish a _______ track offset by 5NM.
parallel
Important for maintaining safe distance from other aircraft
What should be done if ATC clearance is not received?
Proceed as required until clearance is received
Ensures compliance with safety regulations
What should be done with the MCP altitude in case of engine failure?
Set at or below CRZ ALT shown on CDU
Ensures altitude compliance during engine failure
What action is required for electronic checklists during emergencies?
Use electronic Checklist(s)
Ensures systematic approach to emergency procedures
True or False: In oceanic airspace, you should leave track by at least 30° to the left or right.
True
Helps maintain safe separation from other aircraft
What is the procedure for descent below FL290?
Establish & maintain 500ft vertical offset when able
Ensures safety during altitude adjustments
What should be done with exterior lights during emergencies?
Turn on exterior lights
Enhances visibility for other aircraft
What key action is required when executing an emergency broadcast?
Transmit via CPDLC, HF, or VHF
Ensures communication with air traffic control
Aborted Engine Start L,R
Fuel control switch ( affected side)………………….cutoff
Airspeed Unreliable
- Autopilot disconnect switch ………………push
- A/T Arm switch both…………………………..off
3.F/D switch both……………………………………off - Set the following gear-up pitch attitude and thrust
Flaps extended…………..10 degree. 85%N1
Flaps up”……………………..4 degree. 70% N1
CABIN ALTITUDE [QRH 2.1]
- Don the oxygen masks.
- Establish crew communications.
- Check cabin altitude and rate.
- IF cabin altitude uncontrollable:
PASS OXYGEN switch…………………………………………………………..Push to ON and hold for 1 sec
Without delay, descend to lowest safe altitude or 10,000’ (whichever is higher).
To descend:
x Thrust levers to idle.
x Extend speedbrakes.
x If structural integrity in doubt, limit airspeed and avoid high maneuvering loads.
x Descend at Vmo/Mmo.
