I thought the Airbus Autothrottles have to be in the CLB/AT position or above (eg. TOGA
or FLX for take off mode, CLB/AT for other modes) for the Autothrottle to be engaged? So moving it below the CLB/AT (eg. hit the IDLE) position, not anywhere in between) will disconnect the A/T and let the engines go to idle for the touchdown. You can power up the engines again (for whatever reason) manually after that...
What I'm not sure is what if you don't hit the idle detent? Will it disconnect? Or press the A/T D/C below CLB/AT detent?
Mr.BA, yes, those throttles don't move along like the Boeings, which does not allow manual intervention with the exception of A/T D/C or TO
-GA. To disconnect, you need to "sync" the throttle to the corresponding power setting then press the D/C... or just hit idle... (not sure about this last bit).
For Boeings, throttle move along with the thrust setting at all times, under manual or auto throttle. This would give the pilot some comfort if the A/T becomes slow to react... which CAN
(not always does) happen. You can manually intervene and then let go of the throttles and it'll settle according to the A/T.
Not saying one is wrong and the other is right, just a different mode of operation and a different logic.
, in Garuda, the pilots fly with A/T on full time in their SOP. A/T landings require manual intervention to idle the engines in both the bus and the boeing when flaring.
