Hi Kenny,
44019F is the allocated hex of OE-UHK Hoffman HK-36TC Super Dimona, I would suggest you update your d/b to the miscode or alternatively I will update the registration to read as VARIOUS and add the details of the aircraft using the hex code in the CO field. This is an unfortunate consequence of miscoding aircraft.
We use the allocated serial for each aircraft. I would suggest that it you prefer to use the tail number/fleet number instead of the allocated serial that you update your own database accordingly. 881C63 is in the d/b as L16-03/52 and 881C62 has now been added as L16-04/52
Following consultation with forum members when we started out on the database excercise we have standardised on using the country - service for military aircraft worldwide for the CO field i.e UK - Air Force instead of UK - Royal Air Force. As before if you prefer to change from our agreed standardisation I would suggest you update your own database accordingly.
Many thanks for the route updates
Alan
