What purpose do the AUTO XFER switches serve on the electrical
panel? - ANSWER-Used to disable automatic transfer of associated
IDG. If FAIL is illuminated there is a fault preventing auto transfer
A FAULT light on the guarded IDG button indicates what? - ANSWER-
IDG fault due to a HOT-LOP situation
Why would an IDG automatically disconnect? - ANSWER-Over-torque
or over-temp scenario
Will an IDG automatically disconnect when there is low oil pressure? -
ANSWER-No - there must be a high oil temperature or over torque for
it to automatically disconnect
On the electrical EICAS page an AMBER readout of the generator
output indicates what? - ANSWER-Generator overload
,On the electrical EICAS page you see one generator output with half
intensity magenta numbers. What does that mean? - ANSWER-There
is insufficient data being provided
If you were to see amber dashes on the EICAS electrical page in place
of the generator output, what would that mean? - ANSWER-The data
being provided is invalid and thus has been removed.
What is the voltage, phase, and frequency of the IDG's? - ANSWER-
115v, 3 phase, 400hz
Why is the ADG bus not shown on the EICAS electrical page normally?
- ANSWER-It will only display when the ADG is deployed and
producing power
The EICAS synoptic page has the word DISC next to one of the IDG's.
What does this mean? - ANSWER-The IDG has been manually or
automatically disconnected. What? Did you think it meant you were
gonna play a sick game of frisbee golf? You basic bitch.
AUTO XFER OFF in white vs. amber would mean what on the EICAS
electrical page? - ANSWER-If white the AUTO XFER switch was
selected off by the pilot, if in amber the automatic transfer function
has failed.
Voltage output of an IDG turns WHITE when what parameters are
exceeded? - ANSWER-Less than 108v or more than 130v
You see SERVICE CONFIGURATION on the AC electrical page, what
does this mean? - ANSWER-External AC power is hooked up and has
been selected from the external service panel. ONLY the AC service
bus will be powered.
, What would have to happen to get the caution EICAS message
GEN1(2) OVLD? - ANSWER-An IDG exceeded 40kVa.
What would an IDG1 amber caution message tell you? - ANSWER-A
HOT/LOP situation has occurred on IDG1
If the red EMER PWR ONLY warning presents on the EICAS, what has
happened? - ANSWER-Indicates the ADG has deployed
You see a white ADG FAIL status message, what does this tell you? -
ANSWER-The GCU of the ADG has failed. Probably shouldn't have had
your 550 serviced at Jiffy Lube dummy....
Name a few items on the AC Service Bus - ANSWER-Water system,
toilet, APU charger, cabin lighting, logo lights
What does the ADG power? - ANSWER-AC ESS Bus, Hydraulic pump
3B, Stab Trim channel 2, slats and flaps at half speed
What protects the ADG from frost or ice accumulation in flight while
stowed? - ANSWER-An internal heater that comes on when the nose
gear is retracted
After an ADG deployment you get the APU running. What must you do
to connect the APU to the electrical system? - ANSWER-Press the PWR
TXFR OVERRIDE switch on the ADG control panel
What is the purpose of the UNIT switch on the ADG panel? - ANSWER-
It tests the auto-deploy system of the ADG
Why are most aircraft systems DC powered when the aircraft produces
AC power? - ANSWER-AC power is more efficient to produce because
of lighter and smaller components, but batteries only use DC. In an
emergency with only battery power available systems must utilize DC
