Hi Mark, thank you for following up. I do agree with some of the above posts, that certainly from an audio perspective, the spool time is too fast. If your sound engineer has the cycles, I think it would be worth digging into a little more, using my video as reference and comparing the audio to the FADEC n1 displays. Like I said, it appears to me that:
FADEC n1 display response to thrust lever angle=Correct
Audio n1 response to thrust lever angle=Incorrect
However, I do appreciate that the team may have other priorities so I will stop nagging
Thanks!
