Possibly a bit of a daft question, but how do you know how to judge how long it’ll take for an aircraft to get from Point A to Point B when you’re controlling?
I was controlling last night and had a reasonable backlog of planes on the ground waiting to takeoff. I also had a few planes approaching to land. I found it difficult to judge how much time it was going to take a plane to touchdown once on the glide slope and whether I had enough time to clear the planes on the ground to takeoff. I ended up with a queue of (very patient!) planes on the ground as I faffed trying to figure whether I could let them go. Compounded was the fact that the airport was one like London City and they had to back taxi(?) to get to the start of the runway.
Suggestions and piss-taking all gratefully received :-)
