25
Backup AC electrical system automatically powers one or both transfer busses when?
Only one main generator available. Power to 1 or both main AC busses lost. Approach mode selected. System automatically selected after start.
26
Back up AC electrical system transfers power
Without interruption & automatically powers selected systems
27
DC electrical system is the primary source of DC power and consists of? And powers?
4 TRUs (powered by AC transfer busses) Powers: L & R Main DC bus Capt Flt instrument bus FO Flt instrument bus
28
Auto start system aborts for
``` Stall Hung start EGT fails to raise Hot start Air pressure insufficient Starter (duty cycle exceeded or failure) ```
29
On the ground AUTOSTART won’t attempt a second start for
Shaft failure Air pressure insufficient No N1 Duty cycle exceeded
30
If no AC power how does the APU get fuel
The DC fuel pump in the left main tank
31
Fwd left AC fuel pump provides fuel regardless of switch power. How?
Pump energises when APU start switch moved to start. | PRESS light out even with switch in OFF position.
32
When APU running will kick off external power and?
Secondary external power becomes AVLBE Primary external powers right main bus. APU powers left main bus
33
APU status display shows?
``` RPM EGT OIL PRESSURE Oil Temperature Oil quantity ```
34
APU Off selector
Closes APU BAI valve Initiates normal shutdown Resets auto shutdown logic
35
APU on selector
Opens APU fuel valve & inlet door Activates AC or DC fuel pump Powers the APU controller
36
APU fault light indicates
Fault or fire detected APU shutdown due to above Momentarily illuminates on self test
37
Cargo fire detection?
``` Fwd & aft each have one smoke detector Each divided into 3 zones 1 zone = an alert If one zone fails the others still work. Two smoke detector fans in each compartment move air around. ```
38
Pressing cargo fire ARM switches
Arms all 5 fire extinguishing bottles. Arms selected compartment flow valve. Turns off fans. Commands packs to provide minimum airflow.
39
Pulling an engine fire handle? 3-2-1-o
``` Closes 3 valves: engine fuel Engine bleed air & hyrdraulic fluid Depowers 2: reverser isolation valve & depressurises hydraulic pump Arms 1: fire extinguisher O pens generator fields ```
40
Autopilot is only available in which mode?
Normal
41
In normal Mode what envelope protections do you have?
Works Autopilot on or off Stall protection Over speed protection Bank angle protection
42
In normal Mode PFCs automatically compensate for:
Thrust changes Configuration changes Turbulence Turns
43
Primary pitch trim control switches are inhibited when?
The autopilot is engaged. | Pitch trim does not move the control column.
44
Pitch trim moves what? On ground and in air?
On ground stabiliser is directly positioned. | In flight PFC moves stab trim.
45
Autoslats deploy? Armed?
Auto deploy to full when approaching stick shaker. Armed when flaps 1-20 (full at 25/30) Only available in primary mode.
46
Flap/slat load relief in primary mode?
Flaps only. Auto retract to a position that matches speed Will not extend beyond 5/15/20 until airspeed reduced
47
Fuel jettison nozzle switches when armed do?
Opens jettison nozzle valve | Opens both Center tank jettison isolation valves
48
When fuel jettisons TO REMAIN quantity
Main tank jettison pumps shut off. Center Tank jettison valves close. Standpipe at 11,500lbs in each main tank (23,000lbs MIN!)
49
Center hydraulics pumps are?
Primary electric | Demand air driven
50
Center demand hyrdraulic pumps cannot?
Operate simultaneously in ON If both in AUTO both can operate to meet demand.
51
C1 demand pump is dedicated for?
Reserve brake system C2 may be shed
52

54
The PFD & NDs primary source for air data and attitude is?
ADIRU
55
The descent path calculated by the FMC is based on?
Airspeed & Altitude constraints and the EOD (end of descent point)
56
First constraint on the descent based on?
``` Idle thrust Speed brakes retracted FMC cruise wind Wind entries on DES FORECAST target speed Anti ice if required ```
57
Airplane transitions out of approach mode ?
TOGA selected The airplane lands Flies beyond the last waypoint of the approach
58
Acceleration height what happens
VNAV commands VREF +80 | Automatic change from TO thrust to CON thrust
59
If the RAT has been deployed
It cannot be stowed during flight
60
Can the RAT be deployed on the ground?
YES
61
How many air conditioning zones?
7 including F/D
62
