Shutting the aircraft battery off before the APU is shut down causes us to loose what?
Fire Detection. (Always have fire protection)
What does the APU battery provide power to?
Air Inlet Door, APU Control Circuitry and a fuel pump begins to operate.
What does the Aircraft Battery provide during an APU start?
Fire Protection, APU Fuel Valve, DC Fuel Pump, Also supplies control power when the APU battery voltage drops because of heavy loads.
How many APU starts in 60 minutes?
3 Starts
When using the #1 or #2 Autopilot what transponder should be used?
The #1 transponder and the #2 transponder should be used with the #3 Autopilot.
Can we control the DC Fuel pump?
No we cannot control the pump
What are the PSI values for the wing tank pumps and the center wing tank pumps?
15 PSI wing pumps
30 PSI center wing pumps
The wing tank pumps uses motive flow to pull the remaining fuel from center wing. At what point does this occur?
Half Full on the wing tanks
When does the DC pump work?
When on battery power or for a left engine relight
Will the left forward (A/C Pump) always run when the APU is running?
Yes.
Can’t shut if off as long as the APU is running.
The center tank pumps won’t work on the ground unless?
The engines are at 50% N2 -or- the refueling panel door is open.
Fuel Temperature comes from what tank?
Left (767)
Right (757)
Is a separate calculation used from the total fuel quantity?
Yes.
It’s not a total of the three gauges. It’s a separate calculation.
How many hydraulic coolers are there?
1 in the left tank and 2 in the right
What is the minimum fuel temperature?
3° above the freezing point of the type of fuel being used
What does a “Fuel QTY Error” mean?
3000 lbs. discrepancy between FMC fuel calculated vs. the totalizer
What are the two rules when cross feeding fuel?
Rule #1: Don’t crossfeed until cruise +20 Minutes
Rule #2: Open crossfeed valve before turning the crossfeed pumps on.
What does an EICAS “Low Fuel” message mean?
Less than 2200 lbs ±500 lbs.
What does an EICAS “Fuel Config” message mean?
Unbalance of 2000 lbs. ±500 lbs.
IDG “Drive Light”
HOT / LOP
High Oil Temp / Low Oil Pressure
Can the APU Generator power both Bus’?
Yes
Will you get a light if you requested power from the APU and no power is provided?
Yes
When you see the External Power “Avail” light it means?
Good Quality Power
What are the three reasons for the AC Utility Bus to trip?
- Loss of Gen
- Overload
- APU during a start
Is the ground handling bus de-powered in flight?
Yes.
Its powered by the GPU or APU
What provides power to the Ground Service Bus?
Ground Handling Bus while on the ground and connected to external power or the APU.
Select the “Switch” & the APU & Main Batteries will charge.
In flight, the ground service bus is powerd by the right main bus.
If both DC Bus’ are in “Auto” they will automatically join in the event of a failure.
What happens if either of the “ISLN” switches are selected?
They will not close (Join networks).
Is the HOT Battery bus always powered?
Yes
What is powered when the Battery is turned on?
Battery Bus
Why do we have an HMG (Hydraulic Motor Generator) ?
In-case of a total AC Failure. The HMG can provide AC & DC Power.
What is powered when the Standby Power (STBY) selector is in AUTO?
The standby busses transfer to battery power if normal AC power is lost.
When you push in the Battery (BAT) switch what happens (STBY POWER AUTO)?
When on an unpowered aircraft:
- A few annunciator lights illuminate
2. Allows the APU to be started
3. Powered airplane inflight or on the ground when AC power is removed or lost
- The standby (AC/DC) and (2)battery busses are powered (Hot battery and battery)
In the event the HMG is powering the Aircraft what light will you see next to the BAT on button?
The “DISCH” light will appear until the battery voltage lowers to the HMG voltage. Which is lower than the AC system.
What powers the DC Electrical System?
TRU’s or Transformer-Rectifier Units
During Autoland, the busses isolate to allow three independent sources of power to power the three autopilots, they are configured how?
- The left main system powers the left autopilot and the captain’s flight instrument transfer bus.
- The right main system powers the right autopilot and the first officer’s flight instrument transfer bus.
- The battery / standby system powers the center autopilot.
When above 200 feet during Autoland, the loss of a generator results in?
- Both bus tie breakers close and the operating generator powers both left and right A/C busses.
- The left main system powers the center autopilot.
- NO LAND 3 appears on the Autoland Status Annunciator.
When below 200 feet during Autoland, the loss of a generator results in?
“Lockout”
1. Both bus tie breakers remain open.
2. The autopilot associated with a failed generator is unpowered.
3. The flight instruments remain powered through the flight instrument transfer busses.
4. The autoland continues using the remaining two autopilots.
If both main AC busses are lost, what powers the captains flight instruments?
The HDG (Hydraulic Driven Generator) Powers the captains instruments.
Each of the three autopilots is checked for what items?
F - Flight Control Computers
I - ILS’ / IRS’
R - Radio Altimeters
E - Electrical Systems
S - Servo’s (Autopilot Servo’s)
The Pnueumatic “ISLN” valves only open during?
Engine Starts
The Air Demand Pump provides power for what two large demand systems?
The Gear and Flaps Note: If Center air is not working the Gear & Flaps will still go up and down, albeit slowly.
The Auto Rate “Tick” mark on the Cabin Altitude Control panel provides what rates?
Limited to 300⇣ Down & 500⇡ Up
In the event of a pressurization system failure while in one of the AUTO modes?
The system will switch to the other AUTO systems automatically.
How many motors on the outflow valve?
3 Motors:
1 DC Motor. 1 for the manual pressurization system
2 AC Motors. 1 for each automatic pressurization system.
The “Cabin Altitude” Message comes on when?
10000 Feet.
At 11000 Feet a message is sent to close the outflow valve.
At 9000 Feet the outflow valve becomes available again.
At 8500 the message goes away.
What do the positive pressure relief valves and negative pressure relief doors do?
