I just had a random (and practically useless) question about Flight Sim:
Say you're at an airport with a runway 1/19 (to simplify, I'll consider any other runways as closed). The wind is 030@13 (the speed doesn't matter, just the direction). The runway in use is runway 1.
Then the wind gradually changes to 150@15. All operations have to (or at least should) switch to runway 19.
My question is, how does this transition happen? At a relatively calm airport, I suppose it can happen easily when no one is using the runway; but what about busier airports? Are the A/C told to taxi to the "new" runway and just stay there until the A/C using the "old" runway are done?
Any insight, speculation, theory or rumor appreciated.
