# Can active flight plan be sent for the aircraft in the air? [closed]

We are processing some aviation data and I wonder if it is possible that flight plan message can be sent for an active flight (aircraft in the air)?

In the documentation we have the sentence: "Active flight plan, aircraft is in the air. For ARTS III indicates an overflight"

In these sorts of cases, you may see the first FPL message after the aircraft has departed. The departure aerodrome, if known, may appear in the ADEP field (field 13a), or it may be ZZZZ for an unknown aerodrome, or it may be AFIL for an "air filed" flight plan.
