Please can you consider adding a Serial Number / MSN field to the aircraft profile.
Registrations change, (airplane) serial numbers do not. Once a S/N is entered it could become an uneditable field.
Ideally it would be formatted the same as the POH and as shown in G-INFO e.g. 28-XXXXX.

SD could then use the S/N to check the correct aircraft profile has been selected.

(Other apps such as POH Performance (C172, C182, PA28 etc.) use the serial number to check the correct POH version is used as the data source (usual caveats apply) for performance calculations.
It would also aid any future development of takeoff and landing performance to be built directly into SD, although I understand the reluctance for this very desirable feature). Thanks.
