I recognize that we are a minuscule portion of the flying public, but how do people log flights on aircraft that aren’t available for selection in the app? I’ve got a few (C-5, C-17, C-130, etc) where I put a note on the flight with the service and aircraft type, but was wondering if there’s a better way. Is there a way to record helicopter flights that don’t start or end at an ICAO recognized airfield?
