As with SimConnect_AICreateEnrouteATCAircraft there should be some way of
setting a flight number when sending a flight plan to
SimConnect_AICreateParkedATCAircraft using SimConnect_AISetAircraftFlightPlan.
Currently only the registration can be set. The ATC_Airline from the
aircraft.CFG should also be used as with enroute aircraft.

Agree it would be quite nice if it was wrapped up but can also be set via sim
var on success of the insert and it will apply straight away. What does seem
to be the case though if you set ATC_Airline via sim var - ATC doesn’t reflect
the update until after the aircraft takes off.
