Q

When will the backup generators automatically provide power to transfer bus(es)

A
  • Power to one or both Main AC buses is lost
  • One AC generator (including APU)
  • Approach mode is selected
  • Testing
24
Q

If emergency lights are armed what causes them to illuminate

A
  • An armed exit is opened
  • Loss of DC power
25
When does the supernumerary oxygen deploy
Cabin altitude 13,500ft
26
What conditions will cause the RAT to deploy
- Both engines failed with center hydraulic system pressure low - Both AC transfer buses unpowered - All three hydraulic system pressure is low
27
What conditions cause the seatbelt light to turn on when in AUTO
- Below 10,000ft - Landing gear not up - Flaps not up
28
What conditions will cause seatbelt lights to illuminate regardless of switch position
- Cabin altitude above 10,000ft - Superneumery oxygen on
29
How are cargo fires detected
Smoke detectors in each zone. 8 zones main cargo deck 3 each FWD and AFT cargo deck
30
When does RTO become available
- On the ground - Both thrust levers to idle - Above 85kts
31
How are the Primary Flight Controls powered
- PMGs - PSA - Flight Control DC bus - TRU - DC Main bus - Hot Battery Bus - RAT
32
When will the E/E cooling automatically configure to OVRD
- Both fans fail - Smoke detected - Low airflow detected - LWR Cargo Fire ARM switch pushed
33
What happens when the E/E cooling is OVRD
- Both fans are OFF - Overide valve is open - FWD Cargo heat valve is closed - NGS is OFF - OVRD is illuminated
34
What controls flap positioning in all modes
FSEU - Flap, Slat, Electronic, Units
35
What protections available in Primary mode of secondary flight controls
- Load relief (Flaps) - Autoslats - Motion uncommanded - Asymmetry flap/slat
36
What protections available in Secondary mode of secondary flight controls
- Load relief (Slats >256) - Asymmetry flap/slat - Motion uncommanded
37
Where will the slats travel when initially in secondary mode
Full position
38
Stall protection sequence of events
- Pitch Limit Indicators show near Min Maneuver speed Top of Amber - Trim reference speed changes in nose up inhibited Midway through AMber - AIRSPEED LOW displays If A/T armed - A/T to THR mode and accelerates to min maneuver or MCP speed whichever is higher
39
When will auto slats work
- Primary mode only - Flaps <25 degrees )Not in full position) - Extends to full position with signal from stall computer, retracts after signal removed.
40
When is the wheel to rudder crosstie available
Less than 210kts
41
TAC is available and will compensate when
- Above 70kts - More than 10% thrust difference between engines detected.
42
When is TAC unavailable
- Less than 70kts - Thrust reverse - Engine data is lost or system malfunction
43
When will the RAT deploy automatically
- Both AC transfer buses unpowered - Both engines have failed and center hydraulic pressure low - All three hydraulic system pressures low
44
What does the RAT power
Electrically - C1 and C2 TRU Hydraulically - Center primary Flight Controls
45
What is available on the Hot Battery Bus
- Fire Protection - ADIRU (if no other source)
46
What is the ground handling bus used to power
- Cargo loading/unloading - Refueling/defueling
47
Ground service bus powers
- Cabin lighting and outlets - APU and main battery charging
48
DC systems
- PFD's - ND's - GPS - ADIRU
49
When will the backup generators supply power
- Power to one or more AC main buses lost - Only one generator source (including APU) - Approach mode is selected - Initial test after engine start
50
How many backup generators supply power at once
One
51
What supplies standby power
Battery for at least 5 mins
52
How are the generators configured for autoland
- Left IDG supplies the left AC main bus - Right IDG supplies the battery bus - A backup generator powers the right AC Main bus
53
What EEC protections in Normal mode
