Airport Code N30 (Cherry Ridge, Honesdale, PA) shows in the list of Pennsylvania airports but results in an error message when clicked on from an aircraft flight list (N1824H) :
Unknown or Invalid Airport Code
Hint #1: Airport code must be a 3 or 4 digit ICAO (e.g., AUS/KAUS) or FAA (e.g., 3R9 or CA35) code.
Hint #2: IATA codes are not currently supported (i.e., Tokyo/Narita’s ICAO code is RJAA, not NRT or KNRT).
