Once the thrust levers are placed in this detent, the AUTOTHRUST will command thrust anywhere from IDLE, to MAX CLIMB thrust depending on what speed you select on the FCU
Is it possible you miss the point the A/THR was very probably in THR CLB, the AP/FD VERTICAL MODE was in OPEN CLB and the FCU target altitude was 15000 feet ?
Whatever speed is selected at this time will not interfere in any way on the A/THR status which will still maintain THR CLB.
Selecting a different speed will only modify the pitch attitude.
Do you understand the A/THR is NOT in SPEED mode ?
Rcallahan, up to now you wrote only 5 posts on PPRuNe, but and all of them on that specific issue … you must have additional information we are not aware of ?
After the initial thrust reduction due to bird strikes, there are possibilities for the A/THR to command THR IDLE … but that would require additional action(s) from the crew …
Up to now, none such action(s) have been made avail to the public ... but I'm ready to hear ... ?
