|
|
|
With the hydraulic switches set to AUTO, when will the ACMPs turn ON?
|
Pump 1B - IDG 2 operating
Pump 2B - IDG 1 operating Pump 3B - IDG 1 or IDG 2 operating Any pump - flaps NOT in 0 degree position Basically, must have an IDG from the opposite side operating and air flowing over extended flaps |
|
|

|
1 & 2
|
|
|
How are hydraulic systems 1 & 2 cooled?
|
Raim air through air/oil heat exchanger
|
|
|
How is hydraulic system 3 cooled?
|
fuel
|
|
|
Under normal operations, which IDG provides power to pump 1B and 2B?
|
1B from AC Bus 2 via IDG 2
2B from AC Bus 1 via IDG 1 |
|
|
When will pump 3B operate when the switch is turned to AUTO?
|
When all generators fail (AC power failure), ADG runs 3B regardless of switch position.
-OR- With either IDG1 or IDG2 operating and flaps NOT at 0 degrees. |
