It is fairly tedious to awake many aircraft on a tile. I'm wondering if there is a shortcut available to wake aircraft in a city, instead of clicking on each, one by one.
Unfortunately there is no such shortcut available right now.
Expect one to pop up soon once the modders get full access to the game.
I tend to wake up aircraft on the same tile by clicking on the tile that has the aircraft, hitting the F key to wake them and then clicking on the hex again which causes the next aircraft to come to focus. If another unit comes to focus, it is either a case or keep clicking or that I have reached full cycle of the unit stack.
Once the aircraft are awake, they will come to life before the end of the turn.
Click, F, Click, F, Click, F etc is my routine.
