How many fire bottles are there for engines and APU?
2 for both engines, one for the APU
What does the fire switch do?
Shuts off: fuel, bleed air, hydraulic sand pump, generator and arms fire bottles
What do the engine fire loops detect?
Fire and overheat
What does pulling the APU fire switch do?
Fuel and bleed air valves shut, APU shuts down if not already, APU inlet door closes, APU generator field and breaker are tripped and the fire bottle is armed.
When operating the fire extinguishers, APU or engine, how long do you hold it?
1 second
If either loop detects a fire in the APU on the ground, what happens?
The APU shuts down and the fire bottle discharges.
What happens if one loop detects a fire?
Nothing, both must detect fire or overheat, except the APU on the ground with both engines shut down or single loop operations.
What happens if the fire switch does not unlock?
The fire override switch can be pressed which is beneath the fire switch.
What happens if one fire loop fails?
The other loop will detect fires
What fire protections do the cargo compartments have?
Each compartment has a single smoke detection unit. The system includes 5 fire bottles, 2 rapid dump and 3 slow release
What effect does arming the cargo fire arm switch have?
Arms bottles, shuts down fans, commands packs to min flow and shuts down cargo heat.
When the cargo disch switch is pressed what happens?
The 2 rapid dump bottles discharge and a 20 minutes timer starts, if the aircraft is still airborne after 20 minutes, the 3 bottles discharge over time. If the aircraft lands or is on the ground one bottle discharges.
What happens if both forward and aft cargo compartments are armed then the discharge switch is pressed?
The extinguishing agent will be divided between the two and not provide enough concentration in either compartment.
What fire protection is there in the wheel wells?
Dual fire loops in each wheel well,only.
If a fire is detected in the wheel well what can you do?
Extend the gear, and land, if required to retract for performance reasons only do this 20 min after fire warning extinguishes.
What runs the L/R hydraulic systems?
Engine driven primary and electric driven demand pumps
What drives the centre hydraulic system?
Two electric primary and two air driven demand pumps and the RAT
How many hydraulic systems are required to power the flight controls?
Any 1

Locked wheel
Which wheels does anti skid control?
All main gear wheels independently
How do you set the park brake?
Press on brake pedals then set park brake lever
How do you release the park brake?
Press on brake pedals until lever releases
When does RTO autobrake activate?
If thrust is reduced to idle above 85kts
How can RTO autobrake be deactivated?
Advance thrust lever
Stow speed brake lever
Press brake pedal
Move RTO selector
What happens to the autobrake after takeoff?
The RTO autobrake knob rotates to off
Can more brake be applied than max auto?
Yes, with manual braking
When do autobrake operate on landing?
When thrust is reduced to idle
How do you dissengage autobrake on landing?
Advance thrust lever
Stow speed brake lever
Press brake pedal
Move RTO selector
When autobrakes have been disengaged after landing, what does the knob do?
Rotates to disarm
How do you display teas on the ND?
Set XPDR to TA/RA and press TFC on eicas control panel
What scale is the ring on the ND for the TCAS?
3 nm
What supplies flight deck oxygen?
One bottle below the floor
When do passenger oxygen masks deploy?
If cabin exceeds 13500ft or the pass oxygen switch is operated
How is a passenger oxygen mask activated?
Pulling on the mask activates that mask only
When do emergency lights activate?
When main DC power is lost or switched on
Can windows be opened in flight?
Yes if depressurised and it is recommended to slow to flap manoeuvre speed
How many spoilers are there?
14
How many ailerons and flaperons are there?
2 of each
What provides pitch?
Elevator and moveable elevator
What protections do the control computers have?
Stall
Overspeed
Bank angle
In normal mode, what protections are available and auto modes?
All 3 protections and auto speed brakes and auto brakes
With respect to the flight controls, what happen ps in secondary mode?
No autopilots No auto speed brakes No protection features (3) Degraded yaw damping No airspeed or inertial data to PFC
How many slats and flap does the 777 have?
2 flaps per side, 1 Krueger flap per side, 7 slats per side
Which control surfaces droop with flap extension?
Ailerons and flaperons
How does elevator feel work?
Normal: variable based on airspeed
Secondary or direct mode: less force flaps down, more flaps up
When does turn compensation work?
Normal mode up to 30 deg aob, partial above 30 aob
How does stall protection work?
Cannot trim below min manoeuvre speed
Autothrottle engage automatically if continued flight in amber band and autothrottles armed
Stick shaker at red speed band
How does overspeed protection work?
You will need continuous forward pressure to maintain overspeed
When is trimming required?
Only for airspeed changes, 1second of trim equals 10 kts
How does the alternate pitch trip work?
Directly control STCM to position elevator, spring loaded to neutral and override autopilot and pitch trim switches.
What does the manual trim cancel switch do?
It rapidly sets 0 rudder trim however not as accurately as doing it yourself
When is yaw damping unavailable?
Secondary mode if inertial data unavailable and direct mode
How does rudder ratio work?
Normally, more deflection at low airspeed, in secondary and direct rudder movement is smaller clean and larger with flaps down.
When does TAC operate?
