Systems Quiz Flashcards
The Emergency Light System, when armed, is automatically activated by:
Interruption of power to the right secondary bus
What is the difference between the Beta Lock Out system and the Beta Backup system?
Beta Lockout prevents the pilot from putting prop in beta in flight; beta backup prevents PCU from putting prop in beta in flight.
What is the maximum tail wind component for take-off or landing?
20 knots
The function of the transformer rectifier unit (TRU) is to:
Convert variable AC to DC
The function of the Bus Bar Protection Unit (BBPU) is to:
Protect the batteries and generators from overloads due to bus faults
What is the 115 VAC / 400 Hz power source for the flight instruments?
Inverters (I think)
Selecting DC ground power will?
Tie the main and main/secondary bus ties and isolate the generators
Maximum ITT during engine start is:
950° C.
How is the blade angle controlled when in the beta mode?
Power levers
What type of engine is installed on the 103 series Dash 8?
PW-121
What is maximum take-off shp rating?
2150 shp
If we use reduce power takeoffs (92% torque), what must the first takeoff of the day be, and what are we looking for on that takeoff?
Must use normal t/o power (99.5%) to verify engine performance (1200Np)
True/False: the ALTERNATE FEATHER switch is lever locked because if the pilot inadvertently bumps it in flight, the propeller will feather.
True
The normal outflow valve is located:
On the rear pressure dome
Illumination of the “cab press” warning light indicates:
The cabin altitude is above 10,000 feet
The fault light on the pressurization controller indicates:
A controller malfunction
If the “AIR COND PACK HOT” caution light illuminates, the system:
Automatically shuts both bleed air systems off
The boot advisory light will illuminate when the boot is inflated to a minimum of:
15 psi
What is the power source for the props and the windshield heat?
115v variable AC
How many prop timers are there?
2
True/false: the PW121 propeller does not have any feather springs or counter weights. All propeller feathering is accomplished by pressurized oil.
True
Should the engine lose all reservoir oil, how will the pilot feather the propeller?
Via the alternate feather system
The _________ switch powers up the PRSOV; the __________ knob adjust the flow through it.
Bleed; min/max
True/false: should the #1 BLEED HOT light illuminate, that PRSOV will automatically close the #1 bleed air line
True
The deice system is upstream/downstream of the PRSOV?
upstream
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
Where do the fire bottles live?
There are two located in the left wing root
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)
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.
What does a #1 ISO VALVE caution light indicate?
When there is inadequate system pressure due to hydraulic fluid loss
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.
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.
What should the crew do if the gear fails to retract on takeoff?
limit airspeed to 140 KIAS and reference the abnormal checklist.
When will the “Weight on Wheels” caution light illuminate?
If the 6 proximity switches do not agree.
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)
