Cannot replicate but I am seeing a different issue: when adding the co-pilot weight, I am not seeing the avatar co-pilot but a passenger avatar, starting on the runway or cold & dark. @UppishWind75631 : do you have some specific steps maybe to follow to get the proper co-pilot avatar ?
I cannot reproduce what you are experiencing about the co-pilot misplaced (but still having the issue with the co-pilot avatar in the G58). I did the following test:
Starting the sim, load 1st the G58 with a co-pilot weight, I am not getting my defined co-pilot avatar but a random passenger character:
You have to use the quick fill slider to add weight for all the passengers including the co-pilot. But the co-pilot is still a passenger character and not your avatar:
So the issue for me is with some aircraft that are displaying a passenger character instead of your co-pilot avatar. No issue related to the co-pilot/passenger position.
I would recommend to update the steps, adding conditions that the SR22 (or equivalent where avatar works) should be 1st selected and spawned and then same parking spot should be selected when spawning with the G58.
