I fly an A340 for an Airline and have often wondered what the Flight Ops department have put in the Equipment field for the Aircraft when filing a flight plan.
I have managed to find all the abbreviations except "P" and "Q" which when looked up in the Aerad Volumes say that it is "NOT ALLOCATED".
I have asked the Flight Ops peronnel and they can't give me an answer, so I would really appreciate it if anyone can shed some light on this topic.
