Power Control Unit
It takes and receives mechanical or fly-by wire input and actuates the flight control using hydraulic power.
If there is no hydraulic power, they will not work.
Why is there not a PCU runaway procedure for the Elevator or Rudder?
Because they have 3 PCUs each. A failed PCU will be held in check by the remaining 2 PCUs.

All happens automatically
What does a BLEED MISCONFIG caution mean? When does it appear?
The engine bleeds are being used to supply both ECS and anti-ice at the same time, with the gear down or flaps not at 0.
Doing this dramatically reduces the engine’s thrust, so this is prohibited in critical phases of flight.
During which phases of flight can you use the engines to supply both 10th stage and 14th stage bleed air?
During Cruise Flight
What protection does the APU have to prevent backflow of bleed air from the engines?
A check valve in the APU bleed air duct prevents air from entering the APU compressor.
The APU LCV interlock provides a second level of protection by interlocking the APU LVC with the 10th stage bleed switch-lights.
How many loops provide leak detection for the 10th and 14th stage pneumatic ducting?
- 10th Stage: 2 loops
- 14th Stage: 1 loop

Both the 10th and 14th stage SOVs will close initially.
The 10th Stage SOVs will remain closed
The 14th Stage SOVs will re-open because these bleed valves “fail-safe” open.

Why is it important to check for an APU FIRE FAIL caution message prior to conducting the fire test?
So you don’t inadvertently fire the APU’s bottle.
This could happen due to the APU’s automatic fire protection while on the ground.
An engine fire occurs after you have terminated the aircraft. Do you have to reconnect AC power in order to actuate the ENG FIR PUSH switch-lights?
No, all of the aircraft’s FIRE SOV’s and bottles are connected to the DC EMER BUS which is a hot bus (always powered)
Would you still be able to detect a fire after receiving an APU, L (R) ENG FIRE FAIL caution message?
It depends on whether the L (R) ENG / APU FIRE FAIL has been caused by a single-false fire or a double fault.
If you are receiving the FIRE FAIL message because of a single-false fire, you would still receive an indication.
It caused by a double fault, you would not receive the message.
What occurs automatically when either cargo smoke detector detects smoke?
- Intake SOV closes
- Exhaust SOV closes
- Heater shuts down
This is all done automatically

In CLB/DES mode, the aircraft will guarantee a minimum climb / descent rate of 50 ft per minute until the desired IAS is obtained.
If you select a new altitude after the FMA is flashing ‘ALTS CAP’, which altitude will be captured?
The original altitude will be captured

When would you select APPR?
When cleared for an ILS approach with a functioning glide slope
Which approaches require NAV to be in the active mode?
LOC, RNAV and VOR approaches
Why should you never trust the lights on the FCP as an indication of active / standby modes?
They do not indicate active modes, they only communicate that BOTH FCC’s are serviceable.
