Falcon 2000 Electrical Exam Questions
and Answers All Correct
What provision does the logic provide allowing the entire aircraft to remain powered if
Generator 1 power is lost during a critical phase of flight? - Answer- If the slats are
extended (critical phase), the LH/ESS bus tie will remain closed powering the left main
bus with the battery bus
If Generator 2 power is lost in flight with all switches in their normal position, what is lost
regarding the electrical system? - Answer- With all switches in normal position loss of
Gen 2 pwr the right main bus will lose power.
What provision does the logic provide allowing some components to remain powered if
Generator 2 power is lost during a critical phase of flight? - Answer- Certain copilot
avionics powered by bus B1 and B2 are powered by A1 and A2 when the slats are
extended.
What remains powered to help the Copilot in the above situation? - Answer- 1) Copilot
PFD
2) Copilot Air Data Reference Panel
3) VOR/LOC 2
4) AHS2/AHRS2
5) ADC 2
6) RH IAPS
If the aircraft is powered by less than any two generators in flight, what is automatically
load-shed by the electrical system? - Answer- Bus A4 and B4 and side windshield heat
are depowered. If no Generators powering the aircraft, mast heating is also depowered.
When a Ground Power Unit is connected to the external power receptacle and the two-
position magnetic breaker switch at the receptacle is turned on (but the EXT PWR
switchlight in the cockpit is not depressed yet), what happens regarding the electrical
system? - Answer- Inhibiting circuitry is activated to cause the Engine and APU
Generator contactors to open, in order to isolate theses sources from the distribution
system.
What additional things happen regarding the electrical system when the final step is
taken and the EXT PWR switchlight is depressed in the cockpit? - Answer- The GPU
contactor (EXT PWR switch light illuminated) and the ESS/RH (RH BUS TIED
illuminates) bus tie relay are closed regardless of R/H bus tie switch position. Battery
contactor opens, BAT annunciator illuminates, battery is not charging and battery solely
is powering the battery bus.
, What is the danger if the APU is running and you ask for external power to be hooked
up but then after the GPU is connected and the magnetic breaker switch at the
receptacle is turned on you forget to push the EXT PWR switchlight in the cockpit? -
Answer- APU contactor will be opened and system will be running off the battery bus
which is not being charged. Battery could discharge.
What is the first thing to check if you turn the BAT switch ON when trying to apply power
to a cold aircraft and nothing happens? - Answer- Check the EXT PWR switch and see
that it is not pushed in.
Is there any protection on the aircraft against over-or under-voltage from the GPU? -
Answer- Yes, the magnetic breaker switch on the GPU bus powers a printed circuit
board that monitors GPU voltage. If voltage > 30V+/-0.5V or less than 16V the PCB will
trip the magnetic breaker switch on the GPU box isolating from distribution system.
Can you read the voltage and amperage that the GPU is providing anywhere in the
cockpit? - Answer- GPU voltage is shown on the right Ammeter, but amperage is not
displayed in cockpit.
Can you start the APU using a Ground Power Unit? - Answer- Yes
Can the battery be charged by the GPU? - Answer- No
When a GPU is hooked up and powering the electrical system, is the battery powering
anything? - Answer- Yes, it is powering the battery bus.
What usage limits are there for the Landing Lights? - Answer- On the ground 15min
on/45 min off, to allow cooling.
With the emergency lighting switch set to ARM, when will the emergency lighting
system activate? - Answer- Set to ARM, emergency lights will activate with loss of
power to bus A1 and B1.
How many possible DC power sources are there for the Falcon 2000? - Answer- Five
What are the DC power sources - Answer- - 2 engine driven generators,
- APU generator,
- 1 24V DC NiCad battery,
- GPU
Does the Falcon 2000 use A/C power, and if so where does it get it? - Answer- Any
equipment requiring alternating current has internal integral inverters.
When the GEN -APU-BAT selector switch is in the GEN position,
what voltage is the left voltmeter indicating? - Answer- Volts on left main bus.
