-
FLT CTL Panel
If the active elevator actuator fails, what occurs?
Control is transferred to the other actuator.
-
FLT CTL Panel
How is roll control normally achieved?
1 aileron and 4 spoilers on each wing.
-
FLT CTL Panel
If both FACs fail is maximum rudder deflection available?
Yes - after slat extension.
-
EVAC Panel
What is checked on the EVAC panel during the COCKPIT PREPARATION check?
- CAPT & PURS switch in CAPT position

EVAC Panel
What would happen if the EVAC COMMAND push button is pressed a 2nd time?
The evacuation alert is cancelled.
-
EMER ELEC PWR Panel
What buses are powered by the emergency generator?

- Emergency generator not supplying AC power
-
EMER ELEC PWR Panel
What is the function of the RAT & EMER GEN push button?
AUTO - RAT will automatically extend if AC BUS 1 & 2 are not powered and airspeed > 100 kts..
MAN - Extends the RAT at any time.
-
EMER ELEC PWR Panel
How long does it take the RAT to extend and provdie power?
8 seconds total (3 secs. for RAT extension, 5 secs. to pressurize the Blue hyd. sys. and pwr. the EMER GEN).
-
EMER ELEC PWR Panel
When should the red FAULT light on the RAT & EMER GEN push button be expected?
During the 8 sec. RAT deployment and pwr. up.
-
EMER ELEC PWR Panel
What powers the EMER GEN?
Blue hydraulic power provided by the RAT.
-
EMER ELEC PWR Panel
What is the output of the EMER GEN?
5 kVA
-
EMER ELEC PWR Panel
What is the output of the Static Inverter?
1 kVA
-
EMER ELEC PWR Panel
Is there another way to deploy the RAT?
Yes, RAT MAN ON from the HYD Panel.
-
EMER ELEC PWR Panel
What is different about this deploying the RAT via the RAT MAN ON (HYD Panel) compared to normal deployment?
Blue HYD pressure only - No EMER GEN
-
EMER ELEC PWR Panel
