As an ATC I find myself always having planes hanging around on the frequency after frequency change approved, would it not just be better for them to be turned out if they receive the message instead of aircrafts having to physically turning out?
This could be done via the same way as when you contact another frequency using ‘switch and send’ but instead of switching you just leave the frequency.
Although planes can be swiped to leave the frequency on the drop down menu, during busy sessions this can be a nuisance for ATC controllers when there is a high volume of departures. It would be much quicker if aircrafts were tuned out by a exit frequency button which is displayed after the frequency changed approved command is given by ATC.
Let me know if you agree, or if you don’t can u think of a better solution?
