When I flew from KSAN to KLAX, after take off at KSAN the ATC said “Transavia 15, frequency change approved, good day!” And after few minutes the ATC said “Transavia 15, Please check out help pages for using ATC instructions” But KLAX was too far away, so I can’t contact KLAX tower or unicom.
So my idea is
In the frequency menu, there is button called ‘destination airport’.
Before take off, make a flight plan to an airport you want to land. Tap ‘destination airport’ and the active frequency’s will appear. So you can switch the frequency Airport after the ATC said: “[callsign], frequency change approved, good day!”
What do you think of this idea?
