Day 14 - All Previous Topics Flashcards
State the four purposes of the boost pumps
Engine start, backup for primary jet pumps, source of pressure for transfer pumps, crossfeed
In the automatic mode, the boost pump will operate when
Fuel feed line pressure drops below 5 psi, fuel feed chamber falls below 11 gallons, engine starting is selected, crossfeed is selected
Where are the electric transfer pumps located and what do they do
In each mid tank, transfer fuel to wing tanks
How is fuel transferred through the jet pumps
Motive flow
If the fuel indicators fail, they will display
Below zero
What are the three electrical power systems of the T-1
Primary direct current (DC), alternating current (AC), and DC standby current
What are the three primary DC power components
Starter generators, battery, and external power
The generators power their respective load buses though __
The main buses
What type of battery is in the T-1
24 volt, 40 ampere-hour lead acid
What does the BATT FDR FAIL light indicate
Battery feeder protection is lost
What does the BATT FDR FAIL light accompanied by EMER BUS FDR FAIL annunciator indicate
Emergency bus is being powered by the LH load bus
What does the BATT FDR FAIL light accompanied by EMER BUS FDR FAIL and BATT CUTOFF annunciators indicate
Ground fault has occurred and battery feeder protection unit has disconnected the battery
T/F - Ground fault protection is provided by the battery protection circuits
TRUE
The standby battery provides power to
Standby attitude indicator, UHF radio, RTU#1, No.1 ITT indicator, electronic fuel control - start, copilot instrument
T/F - If the STBY PWR is not armed during preflight, the standby bus will not automatically be powered with the loss of all electrical power
TRUE
The AC power system is powered by __ located in the __
Two inverters, nose compartment
With the inverter select switch to AUTO how is AC power distributed
The No.1 inverter powers the primary and the No.2 powers the secondary buses by default
With the inverter select switch to NO.1 how is AC power distributed
It forces the No.1 inverter to power the primary buses
With the inverter select switch to NO.2 how is AC power distributed
No.2 powers the primary AC buses and No.1 powers the secondary AC buses
What causes the AC BUS SHED annunciator to illuminate
No.2 inverter is being powered by the emergency bus and the No.1 inverter is failed
While operating on emergency and/or standby power what hydraulic systems will be inoperative
Normal landing gear extension, flaps, speed brakes, anti-skid
The T-1 hydraulic system controls
Flaps, landing gear, speed brakes, and normal braking
What types of hydraulic pumps are utilized in the T-1
Variable displacement, rotary plunger type pumps
The hydraulic pumps delivery and pressure varies from __ gpm at __ psi to __ gpm at __ psi
0, 1500, 3.9, 1400
