A further comment: are you aware you can create multiple profiles for the same aircraft reg?
I have two profiles for my aircraft, as I had it weighed in two different configurations (one in ‘cargo’ mode with the rear sear backs removed, and one in ‘standard’ mode with the rears seats in place for passengers’). With different W&B profiles, I use the correct one for each flight on the day.
If you really found yourself in the situation where you flew two aircraft with the same registration (theoretically possible on the N reg for example), you’d just need to include the types and serial numbers in the profile names.
