What does it mean if the GPU is plugged in, but there is no GPU AVAIL light
illuminated on the button? |
|
Definition
| DC power requirement from the GPU of between 26V and 29V is not being met. |

What are we looking for when we push in the Electrical Emergency Button on
the before taxi checklist? |
|
Definition
That the batteries show at least 23.5 volts.
(The generators continue to power the DC busses in this scenario, but certain
other relays open in order to confirm battery voltage). |

Term
| If the GPU is powering the airplane, when do the generators come on line? |
|
Definition
When the GPU is disconnected (from the Central Bus) which can be confirmed on
the electrical synoptic page. |
|
|
Term
If the GPU is connected and the Electrical Emergency Button is pushed in, what
happens? |
|
Definition
Because the generators are not on-line yet, the electrical system is forced into
electrical emergency, connecting the batteries directly to the emergency buss.
(The GLC 1, GLC 2, SBC 1 and SBC 2 will be commanded to open, and BTC 1 and
BTC 2 will be hardwire locked out, EBC 1 will open and EBC 2 will close).
The Batteries 1 and 2 will supply power to the HOT BATT BUSES, EMERGENCY BUS
and the CENTRAL BUS. |

Term
If a Dual Generator failure occurs in flight, what remains powered?
The aircraft wiring logic will automatically configure the electrical emergency
scenario. The Batteries 1 and 2 will supply power to the HOT BATT BUSES,
EMERGENCY BUS and the CENTRAL BUS providing engine starting. |

If while in flight, the CAS message ELEC XFR FAIL appears, what is the
memory item and why is this procedure necessary? |
|
Definition
ELEC EMER BUTTON…………PUSH IN
A complete in-flight loss of the main generating system has occurred, but the
automatic transfer logic has failed to configure the electrical emergency condition,
so pushing in the button allows the pilot to override the automatic transfer failure
and enable the load shedding process by forcing the system into the electrical
emergency condition. |
