לשיטתך, what if someone took only a helicopter out of these airports, but not an airplane? Could they count it as an airport they flew in/out from? Because it's an airport they flew in/out from, regardless of the aircraft type.
In fact, TEB doesn't even
have a helipad! The helicopters there land on the regular runways. So according to you, if someone took a chopper out of TEB, they can't list it here (it's not a heliport!) and they can't list it in the airport thread (it's not an airplane!).
אלא מאי, the only logical conclusion is that neither the precise type of aircraft nor the precise type of airfield is a deal breaker. So long as you
flew out of a recognized
airfield, you should be able to list it in the regular airport thread.
