I looked in the manual but couldn't find anything. Does a list exist somewhere of all the column headings in database explorer?
What does CM mean in the airport list?
In the aircraft database it's even more confusing.... in the CN column for some aircraft they have entered the Company Name (with the construction number in AC) and in others it's the other way round. Go figure....
I much preferred the heading systems used in AirNav Decoder and AirNav Suite where the column headings were pretty much foolproof.
