Yes
39
Can Main Deck Cargo Handling Bus and Right Sync Bus share the same power source?
No
40
What is the primary source for the Main Batt and APU Batt Buses?
DC Bus 3 (powered either from AC BUS 3 through T/R or by DC Tie Bus through DCIR)
41
If you lost all generators (IDGs) in flight, what would you retain off the standby electric system?
Both STBY buses (Main STBY and APU STBY) now powered by Batteries through Hot Batt buses and STBY INVRs (30 mins power) Buses and key systems retained: Main STBY - Left EIU, CDU, ADC, EFIS Control, Primary EICAS - Various Flight Control Components - Left XPDR, ILS, VOR APU STBY - Left PFD, ND, FMC Main Batt - Fuel and Xfeed valves, APU controller (alternate) - Manual pressurization control, TE Flap control, IDG disconnect - Lights - Dome, Storm (& select interior) - CA's interphone, Left RTP, VHF APU Batt - Engine start air control - Engine & APU Fire/Overheat Detection Loops A & B - FO Interphone, PA System Main Hot Batt - Engine fire extinguishers and Fire Sw Unlock - Engine spar valves - Lower Cargo and APU fire extinguishers - APU Fuel SOV APU Hot Batt - IRU L, C, R DC Power - L&R Outflow Valves - APU Inlet Door
42
Where is the APU ground control unit?
Right body wheel well
43
What is the only control you do NOT have on APU ground control unit?
APU start
44
What things unlock Engine Fire Switch?
Fire warning Fuel Control Switch - CUTOFF Engine Fire Override Switch
45
What things unlock APU Fire Switch?
Fire warning APU Fire Override Switch
46
What does pushing MAIN CARGO FIRE ARM Switch do?
- turns off 2 packs - closes master trim air valve - enables main deck fire suppression - configures equipment cooling to closed loop - turns off all airflow to main deck - turns off all airflow and heat to LLCC
47
What does pushing FWD/AFT CARGO FIRE ARM Switch do?
- turns off 2 packs - closes master trim air valve - arms LLCC fire extinguishers - configures equipment cooling to override mode - turns off all airflow and heat to LLCC
48
What is the difference between pulling an engine START Switch with AUTOSTART ON/OFF
Autostart ON - ARMS start valve Autostart OFF - OPENs start valve (light immediately on) Both then open engine bleed air valve
49
Magenta line on N2 display?
Fuel-on indicator Min N2 RPM to move Fuel Control switch to RUN during MANUAL engine start
50
When must CON IGNITION be on? (Atlas limitations)
Heavy rain Severe turbulence Volcanic Ash Icing conditions Standing water/slush on runway (Auto provided when NAI on)
51
What are icing conditions?
10 degrees or less Visible moisture
52
When is approach idle commanded?
CON IGNITION Switch ON NAI ON Flaps in landing position Reverse thrust
53
How long is approach idle maintained until after touchdown (once minimum idle is selected)?
5 seconds
54
What is the reason for approach idle?
Higher thrust than minimum idle Decreases acceleration time for GA
55
If CON IGNITION Switch fails, what can you use to command continuous ignition?
STBY IGNITION Selector to 1/2
56
Which switches will depressurize EDP?
Engine Hydraulic Pump Switch Engine Fire Switch
57
Why are the hydraulic reservoirs pressurized?
- Prevent pump cavitation - Ensure positive flow during high demand conditions
58
When do demand pumps operate (Hyd Demand Pump Selector - AUTO)?
- Engine pump output pressure low or fuel control switch in CUTOFF - demand pumps 1 and 4 also when TE flaps in transit (ground), or in flight when extended past 1 - High demand - e.g flap transit, gear retraction
59
When do demand pumps 1 and 4 operate automatically (in addition to normal reasons)?
When TE flaps in transit (on ground) Flaps extended past 1 (in flight) - continuous
60
What is the aux pump used for?
Ground handling operations - brake pressure
61
Which brake does Brake accumulator pressure indicator indicate?
Park brake
62
What does 'FLAPS DRIVE' EICAS indicate?
Flaps asymmetry (or flap group failed to move in secondary mode)
63
What does 'FLAPS CONTROL' EICAS indicate?
All FCUs lost
64
What does 'FLAPS PRIMARY' EICAS indicate?
Primary control lost (secondary mode) for at least one flap group
65
What do FCUs provide?
Primary mode Secondary mode Indications and annunciations
66
During thrust reverse, what happens to flaps and what indication will you see?
Auto-retraction of inboard and midspan LE flaps (and then auto-extension when thrust out of reverse) Flap position indicator reflect flaps in transit (green line changes to magenta and then back to green)
67
On ground, when would you see a 'FUEL OVD CTR L,R' EICAS?
CWT pump switches off and CWT > 7,700 kgs
68
How much pressure do override pumps put out in comparison to normal pumps?
Twice the amount
69
What valves close when pushing ENGINE BLEED Air Switch OFF
Engine bleed air valve PRV HP bleed valve
70
What will cause an engine bleed valve to auto-close?
- ground cart supply (to prevent reverse flow) - bleed air over temp - bleed air over pressure - bleed source loss - engine fire switch pulled
71
What causes PRV to close?
- failed closed - any time start valve not closed (inc. failed open) - HP valve failed open and NAI selected (too much pressure) - eng bleed air valve closed
72
What fault will PRV stay open for for thrust reverser, but not for NAI?
HP valve failed open
73
How many PTCs are there?
2 - A and B
74
How many channels for each PTC?
3 - one per pack
75
What must be on for automatic PTC switching (either due to failure or as normal on landing)?
Trim air
76
With bleed valve closed, can NAI function? How?
Yes IP valve as HP valve is closed
77
What items are required to be checked for exterior inspection?
- chocks in place - landing gear door position - flight control surfaces clear - APU exhaust clear (unless running)
