Q

The fault light on the pressurization controller indicates:

A

A controller malfunction

17
Q

If the “AIR COND PACK HOT” caution light illuminates, the system:

A

Automatically shuts both bleed air systems off

18
Q

The boot advisory light will illuminate when the boot is inflated to a minimum of:

A

15 psi

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?

A

2

21
Q

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

A

True

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

A

True

25
Q

The deice system is upstream/downstream of the PRSOV?

A

upstream

26
Q

List the 7 lights that illuminate when the FIRE TEST is accomplished?

A 
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
Q

Where do the fire bottles live?

A

There are two located in the left wing root

28
Q

What lights illuminate with smoke in the baggage compartment? Lavatory?

A

Baggage compartment = SMOKE warning light

Lavatory = audible smoke alarm sound and red light illumination on FA display (there is no flight deck indication)

29
Q

What is significant about operating on Standby Hydraulic Pumps instead of the engine driven pumps?

A

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
Q

What does a #1 ISO VALVE caution light indicate?

A

When there is inadequate system pressure due to hydraulic fluid loss

31
Q

What color is the hydraulic fluid on the Dash 8?

A

It is purple in color, however it appears clear or grayish when found on the ramp or hanger floor.

32
Q

Why do the Hydraulic Quantity Gauges have red dots on the bottom?

A

To indicate power loss for the associated No.1 or No. 2 quantity indicators.

33
Q

What should the crew do if the gear fails to retract on takeoff?

A

limit airspeed to 140 KIAS and reference the abnormal checklist.

34
Q

When will the “Weight on Wheels” caution light illuminate?

A

If the 6 proximity switches do not agree.

35
Q

What components are on each hydraulic system?

A

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)
