Power Up / Throttle Not Properly Working

It seems you are using the A310 from Asobo. The panels are entirely different than the A320neo which I was referring to. I tried using the A310 and also cannot figure how to start it. I’d forget about using that version. You may want to try the A320neo. Very easy to get started and most functions work. Or the third party A320LEAP from Flybywire.
