When the time comes to make a runway change, let's say because wind has changed direction, how is this performed?
- Aircraft might already be on finals, what does ATC do? Do they ask them if they want to continue with the approach or be vectored to another runway?
- Aircraft might not be on finals but being vectored to the finals. Same question here.
- Finally, there might be aircraft on the ground already taxied to the runway. Do they takeoff anyway or do they taxi to the new runway?
