ATC at Prestwick — the simple picture

What is ATC?

Air traffic control is a group of people in a room with radios, telling pilots what to do. Their job is stopping aircraft hitting each other or the ground.

At Prestwick there are three voices you might hear

Ground

Talks to aircraft while they're on the ground — pushback, taxi, parking. You won't hear this much from outside the fence.

Tower

Runs the runway. Says "cleared for takeoff" and "cleared to land". This is the most exciting frequency to listen to because you'll see the aircraft out the window matching the radio calls.

Approach

Handles aircraft flying towards Prestwick from further out — usually 10 to 30 miles away. They line them up for the runway.

A typical arrival, simplified

1. Aircraft flying to Prestwick talks to Scottish Control (high up, en-route)

2. Gets told to descend and switch to Prestwick Approach

3. Approach lines them up towards the runway, then switches them to Tower

4. Tower clears them to land

5. Once on the ground, they switch to Ground to find their parking stand

That's it

That's the whole structure. Every phrase you'll hear on a scanner falls into that chain. When you're ready, read ATC units at EGPK for the frequencies and detail.
