19
Q

What is the power source for the props and the windshield heat?

A

115v variable AC

20
Q

How many prop timers are there?

21
Q

True/false: the PW121 propeller does not have any feather springs or counter weights. All propeller feathering is accomplished by pressurized oil.

22
Q

Should the engine lose all reservoir oil, how will the pilot feather the propeller?

A

Via the alternate feather system

23
Q

The _________ switch powers up the PRSOV; the __________ knob adjust the flow through it.

A

Bleed; min/max

24
Q

True/false: should the #1 BLEED HOT light illuminate, that PRSOV will automatically close the #1 bleed air line

25
The deice system is upstream/downstream of the PRSOV?
upstream
26
List the 7 lights that illuminate when the FIRE TEST is accomplished?
``` Fire warning PIC Fire warning FO Master warning CHECK FIRE DETEC warning light Fuel pull off handle light LOOP A caution light Loop B caution light ```
27
Where do the fire bottles live?
There are two located in the left wing root
28
What lights illuminate with smoke in the baggage compartment? Lavatory?
Baggage compartment = SMOKE warning light | Lavatory = audible smoke alarm sound and red light illumination on FA display (there is no flight deck indication)
29
What is significant about operating on Standby Hydraulic Pumps instead of the engine driven pumps?
The standby pump has a flow rate of 1.5gpm whereas the engine driven pump has a flow rate of 9.5gpm; therefore component cycle time increases significantly.
30
What does a #1 ISO VALVE caution light indicate?
When there is inadequate system pressure due to hydraulic fluid loss
31
What color is the hydraulic fluid on the Dash 8?
It is purple in color, however it appears clear or grayish when found on the ramp or hanger floor.
32
Why do the Hydraulic Quantity Gauges have red dots on the bottom?
To indicate power loss for the associated No.1 or No. 2 quantity indicators.
33
What should the crew do if the gear fails to retract on takeoff?
limit airspeed to 140 KIAS and reference the abnormal checklist.
34
When will the “Weight on Wheels” caution light illuminate?
If the 6 proximity switches do not agree.
35
What components are on each hydraulic system?
No. 1 Main Hydraulic system operates (FAIR): Flaps Anti – Skid Control Valve/Mainwheel Brakes Inboard Roll Spoilers Rudder Actuator (lower) ``` No. 2 Main Hydraulic System operates (LONGER): Landing Gear Outboard Roll Spoilers Nosewheel Steering Ground Spoilers Emergency/Parking Brakes Rudder Actuator (Upper) ```
