When N2 reaches 50%.
What is the role of FADEC during a manual engine start?
It controls the start valve, the HP fuel valve and ignition.
What causes a FAULT light to appear in amber on the engine panel (under the engine master).
Position of the HP shut-off valve is abnormal.
The automatic start sequence of the associated engine aborts.
There is a malfunction of the thrust control.
What are the name f the FADEC engine idle modes?
Modulated, Approach and Reverse.
When does approach idle activate?

What happens if cabin staff initiate and emergency call to the flight deck?
EMER/CALL pb flashes and a buzzer sounds 3 times. Along with a flashing ATT light on all 3 ACP’s.
What is the function of the LGCIU?
The landing gear interface unit sends gear position information from proximity detectors to other aircraft systems.
What happens when the gravity extension is tuned?
1st turn isolates the landing gear hydraulics from the green system. 2nd turn unlocks the landing gear doors. 3rd turn allows gravity extension to drop the gear into the extended position. The doors remain open.

Tiller - 80kts.
How much nose wheel steering is available through the rudder and tiller?
Rudder pedals - 6 degrees.
Tiller - 75 degrees.
When is NW STRG DISC amber and green?
It’s amber if one engine is running and green when the selector is in the towing position and no engines are running.
What system is the autobrake on?
Green. Remember autobrake is a deceleration rate so despite reverse thrust it stops in the same distance. On an RTO with MAX autobrake, this is not a rate of deceleration, it is just max braking.
How long can the park brake be on for?
The accumulator should last for 12 hours.
What delays occur with LO, MED and MAX autobrake?
LOW - 4s after spoilers deploy (1.7m/s decal rate).
MED - 2s after spoilers deploy (3m/s decal rate).
What temperature must the brakes be below for takeoff?
150 degrees.
What are the immediate actions for loss of braking?
Max reverse, release pedals, command a/skid off, press for 1000psi max.
what roughly is the total fuel capacity?
19004kg.
What is the minimum quantity of fuel for takeoff?
1500kg.
If all of the tanks are full, what is the normal sequencing for fuel?
Start - centre tanks.
Flaps for T/O - Inner tanks for each engine.
Flaps up + 500kg used - goes back to the centre tank and empties it. When the centre tank empties it automatically switches over.
When inner wing tanks get to 750kg, fuel is automatically transferred from the outer. 1st inner cell < 750kg 1st transfer valves open on each side. 2nd inner tank < 750kg 2nd transfer valves open on each side. Outer transfer valves close on the next refuelling.
Describe over-full and under-full tanks..
Over-full - tanks are full.
Under-full - wing tanks are down 500kg to allow fuel from the IDG to return to each tank.
What happens to the centre tank pumps when the slats are extended within and after 2 minutes of engine start?
Within 2 minutes - Centre tank.
After 2 minutes - Inner tank.
What causes the FAULT light to illuminate on the mode select switch on the fuel panel?
When the centre tank has more than 250kg of fuel and the left or right wing tank has less than 5000kg.
What does a square with a line through it represent on the E/WD?
A pump.
On the SD what is indicated by a tank fuel quantity being boxed yellow?
Both transfer valves have failed to open.
What type of warning is a fuel imbalance?
Advisory.
What will happen to the flight displays if the shed bus is not live?
The captain will lose his ND.
What is the max KVA for the generators?
GEN 1, GEN 2, APU GEN = 90KVA.
EMERGANCY GEN = 5KVA.
what does the 25.5 volts on start-up mean?
There is sufficient charge to start the APU.
What 4 supplies are there to the AC Essential feed.
AC Bus 1, AC Bus 2, Emergency Gen, Bat 1 via the static inverter.
If TR1 fails, what supplies the DC Essential Bus?
The Essential TR.
Which busses get powered when the aircraft is on battery power only?
AC Ess Bus and DC Ess Bus
In flight can the APU be started?
Yes, 45 seconds after the failure to allow the emergency generator to come online and below FL250.
What is the normal pressure of the bleed air?
45psi +/-5psi and 200 degrees.
When would you expect to see the HP valve open?
On the ground and at low thrust settings like in the decent.
Which bleed supplies can be used simultaneously?
Eng 1 and Eng 2 bleed.
Is wing anti-ice allowed if one bleed system is operating?
Not if both packs are on. One pack must be switched off. You would get sufficient air from the heat exchanger but it will burn out the pack (pre-cooler performance).
What happens if a BMC (bleed monitoring computer) fails?
Leak detection for that side is lost. BMC 1 provides leak detection for ENG 1, wing loop A and the APU duct.
What are the implications of using ground power air?
If its LP air, you musnt run the APU BLEED and packs must be off. You can however run the APU for power. If its HP air you must run the APU and it is merely used for starting the aircraft.
What are the functions of ACSC (air conditioning service computer) 1 & 2?
ACSC 1 runs the number 1 pack, manages the hot air pressure regulating valve and cockpit trim valve. ACSC 2 runs the number 2 pack and the forward and aft trim air valves.
What are the range of temperatures on the temperature controller.
18 degrees in cold position, 24 degrees in the 12 o’clock position and 30 degrees in the hot position.
What happens to the pack flow valves during engine start?
They automatically close.
When does the pack ram air valve open after landing?
20 seconds after the speed drops below 70kts. In flight you’d want ram air if both packs have failed. Initially your cabin altitude would rise. Remember the ram air valve has a differential pressure of just 1 psi so if the pressure difference is greater than 1psi the ram air valve wont open. Without packs, air is just re-circulated.
Describe cabin pressurisation on T/O and LDG.
On T/O or LDG the cabin pressure goes to airfield elevation -300 for passenger comfort. 55 seconds after touchdown outflow fully opens. On a side note, cabin altitude has an 8.3 differential pressure rating so cabin alt can be zero at 20000ft. Anything after that the cabin alt will rise.
What is the max ROD of the cabin in AUTO?
750fpm.
In the ground mode at high skin temperatures, which config is in operation?
The open circuit config. 12 degrees is the decider. If the temperature is higher than 12 degrees, its in open config. If the temperature is lower than 12 degrees, its in closed config. In flight, the deciding temperature is 35 degrees. If it is greater than 35 degrees, its in the intermediate configuration. Otherwise its in the closed config.
How many fire loops and bottles are there per engine and APU?
2 loops for all. 2 bottles per engine. 1 bottle for the APU.
When is the squib light illuminated?
When the squib is armed for discharge.
How many smoke detectors are there for cargo fire extinguishing?
ETOPS system has 2 detectors in the forward compartment and 4 in the aft compartment. FOR THE TEST: there is 1 fire bottle which can be fired into the forward or aft compartment.
What are the 4 occasions when the ALIGN light will flash?
1) Respective IR is in align mode.
2) IR alignment fault/no present position entry after 10 minutes.
3) Difference between position at shutdown and entered position.
4) Aircraft is moved during alignment.
What is the immediate memory action for unreliable airspeed at Vr?
TOGA, 15 degrees pitch.
When an ILS is tuned on an RMP, what information is not available?
DME distance on the PFD.
Which procedure has to be applied first in case of simultaneous failure of ADR and IR fault (same ADIRU)/
ADR fault procedure before IR.
What is the difference between the sweep on the weather radar and terrain?
Weather radar is a single sweep, terrain is a double sweep.
What produces the information on the ND when using EGPWS?
FM1, captains rad alt and baro alt.
What are icing conditions defined as?
TAT or OAT at or below 10 degrees and visible moisture (1600m or less).
