Text Review for Systems Flashcards
In the event of a dual generator failure in-flight, how long should the main aircraft batteries last?
30 Minutes with the small original batteries, or 50 minutes with the larger NiCad /Lead Acid batteries.
The main battery connectors will open automatically if:
Battery voltage drops to less than 14 VDC for more than 10 seconds with the airplane on the ground.
What will the generators do after engine start with a GPU connected?
The generator will automatically come online when the GPU is disconnected.
Normally, the two generator busses act independently; however, they are automatically tied together when?
During engine start
Following a single gen failure
When using either the GPU or APU for power
Which buses are automatically isolated from the main electrical system during engine start to prevent voltage spike damage?
Emergency
Main Avionics
Essential
Essential Avionics
What voltages are indicated on the EICAS/MFD SUMRY and ELEC system schematic pages?
Emergency Bus
L and R Essential Busses
Which lights can be operated from the hot busses with the aircraft batteries turned off?
Aft equip bay and baggage compartment lights
SPPR area pylon light
Baggage area pylon light
The activation of the emergency lighting system is controlled by a timing circuit and limited to a certain amount of illumination time. How long will the lights be illuminated?
Minimum of 10 minutes and a maximum of 12 minutes
How is an ADC failure indicated?
A red X over the airspeed, altitude, and a red VSI on the corresponding failed side PFD.
When is engine page 1 automatically displayed on the RMU?
When neither IC/SG is providing EICAS to either DU.
The amber ALT comparison monitor on the PFD illuminates whenever:
The baro altitude disagrees by 200ft or more between display units 1 and 4.
If both avionics switches are OFF due to dual gen failure, which displays are available?
PFD or EICAS can be displayed on DU2, until its turned off or left main battery fails.
The engine pages can be displayed on RMU 1 or 2
The navigation page can be displayed on RMU 1 or 2
The BARO or Radio Altimeter instrument approach minimums are displayed how?
As a digital readout to the right and below the ADI
As a magenta bar on the altitude tape
As an amber MIN annunciation on the ADI
The standby fuel pumps are used for all except?
Wing to FUSELAGE transfer
During flight, fuselage fuel is transferred to the wing tanks through:
Gravity and jet pumps located at the end of the transfer lines.
Which of the following statements are incorrect?
An amber FUEL IMBALANCE CAS will be posted anytime the fuel balance is greater than 200 lbs.
An amber L or R FUEL QTY LOW CAS will be posted whenever the corresponding wing fuel is 350 lbs
A white L or R FUEL BAY LOW CAS will be posted when the collector tank is less than 80 percent
None are correct
Engine instrument indication can be displayed on:
Either inboard display unit
Either RMU
An amber IGN annunciation on the EICAS indicates?
Ignition is ON and both igniters are bad
Automatic ignition is provided during:
Excessive engine deceleration
Engine start sequence after the START button has been depressed
Un-commanded engine deceleration
The DEEC functions to provide all of the following except:
Engine overspeed protection
N2 reference bug display
Thrust management
Automatic performance
N2 reference bug display
Depressing an engine FIRE PUSH switch closes what?
The main fuel shutoff
The ECSPRSOV
The hydraulic fluid supply
Thrust reverser isolation valve
When an overheat or fire condition is detected within an engine nacelle, all of the following warnings are activated except:
A red FIRE light is displayed on the CWP
If both channels (A and B) of a DAU fail, how will the engine instrument display on the EICAS be affected?
The indications for N1, N2, ITT, oil pressure, oil temperature, and fuel flow will be lost.
In the manual engine mode of operation, all of the following are true except:
Automatic ignition is provided during an air start
