|
|
|
How does the system know whether you intend to fly a
CAT 1 or CAT 2 ILS? |
Through the correct use of the RA/BARO selector and
RA minimums setting. The system arms for the highest capability available. |
|
|
Describe the two ILS Approach Check Points.

Yes, there will be an EICAS message
|
|

|
The autothrottles retard at 30 feet in landing
configuration. The autothrottles disengage at WOW or Wheel Spin Up. |

|
No, the OVRD message is displayed on the FMA
|
|

to disengage? |
They will disengage if the thrust lever is moved
beyond TOGA position. During an Abort when the TLA is reduced below 40 degrees in the TO HOLD mode. |
|
|
Does the failed engine thrust lever remain active with the
autothrottles on during single engine operation? |
No, it is deactivated but the operating engine autothrottle
remains active. |
|
|

It is the Thrust Rating Selection key and it allows manual
selection of following thrust settings to be transmitted: TO GA CLB 1&2 CRUISE CON |
|
|
Normally the engine thrust rating changes from TO to
CLB at 400 feet on takeoff as long as a vertical mode has been activated and gear is up. What happens if no change in vertical mode is detected? |
