Prestwick Frequencies Guide
Prestwick Frequencies Guide
Every controlled airport uses a set of radio frequencies so that pilots and air traffic controllers can communicate. At Prestwick, there are several key frequencies, each serving a different purpose. If you listen to aviation radio (using an airband scanner or an online feed), understanding which frequency does what will help you follow the action.
How Aviation Radio Works
Aviation communication uses VHF (Very High Frequency) radio, operating in the frequency band between 118.000 MHz and 136.975 MHz. Transmissions are in the clear (unencrypted) and use AM (Amplitude Modulation), which means anyone with an appropriate receiver can listen in.
All communication follows strict protocols. Pilots and controllers use standardised phraseology to avoid misunderstandings. Every transmission includes callsigns, and critical instructions (like runway clearances) are always read back by the pilot to confirm they were received correctly.
The Key Prestwick Frequencies
Here are the primary frequencies you need to know at EGPK:
| Frequency | Service | What It Does |
|---|---|---|
| 118.150 MHz | Prestwick Tower | Controls the runway โ takeoff and landing clearances |
| 120.550 MHz | Prestwick Approach | Guides arriving aircraft from the surrounding area to the runway |
| 129.450 MHz | Prestwick Radar | Radar service for aircraft in the Prestwick area |
| 121.125 MHz | ATIS (Scottish Information) | Automated weather and airport information broadcast |
Prestwick Tower โ 118.150 MHz
This is the frequency that controls the runway and the immediate airfield environment. When a pilot is ready to take off, they receive their clearance on Tower frequency. When an arriving aircraft is on final approach, Tower gives them clearance to land.
Tower also manages aircraft taxiing on the manoeuvring area (runways and taxiways) at Prestwick. Unlike larger airports that have a separate Ground frequency, Prestwick typically combines tower and ground control on the same frequency, reflecting its lower traffic volume.
Typical calls you might hear:
- "Ryanair 1234, cleared to land runway 12, wind 250 degrees 15 knots"
- "G-ABCD, line up and wait runway 12"
- "Ryanair 5678, cleared for takeoff runway 12, surface wind 260 degrees 12 knots"
Prestwick Approach โ 120.550 MHz
Approach control handles aircraft that are arriving at or departing from the airport but are not yet (or no longer) on the runway. An inbound aircraft might first contact Approach when it is 30 or 40 miles away, descending from cruising altitude.
The Approach controller sequences arriving traffic, issues headings and altitudes to guide aircraft onto the final approach path, and ensures safe separation between aircraft. For departing aircraft, Approach may provide an initial climb-out service before handing them over to the area control centre (Scottish Control).
Typical calls:
- "Prestwick Approach, Ryanair 1234, descending through flight level 80 for the ILS runway 12"
- "Ryanair 1234, turn right heading 090, descend altitude 3,000 feet, QNH 1013"
Prestwick Radar โ 129.450 MHz
Prestwick Radar provides a radar-based air traffic service to aircraft operating in the wider Prestwick area. This can include traffic that is transiting through the area rather than landing at or departing from the airport. It may also be used when Approach control is providing a radar service.
The distinction between Approach and Radar can seem blurry, and in practice at a quieter airport like Prestwick, the same controller may work both. The key point is that 129.450 is used for radar services.
ATIS โ 121.125 MHz
ATIS stands for Automatic Terminal Information Service. It is a continuously broadcast recorded message that provides pilots with essential information before they contact a controller. At Prestwick, this service is branded as "Scottish Information" because it forms part of the Scottish FIS (Flight Information Service) network.
The ATIS broadcast is updated regularly (typically every 30 minutes or whenever conditions change significantly) and includes:
- Information designator โ a letter (Alpha, Bravo, Charlie, etc.) so pilots can confirm they have the latest version
- Active runway โ which runway is in use
- Wind โ direction and speed
- Visibility โ in metres or kilometres
- Cloud โ amount and height
- Temperature and dew point
- QNH โ the atmospheric pressure setting pilots need for their altimeters
- Any significant information โ runway works, taxiway closures, equipment outages
When a pilot first contacts Approach or Tower, they say something like: "Prestwick Approach, Ryanair 1234, information Charlie." This tells the controller the pilot has listened to ATIS update Charlie and is up to date.
Other Frequencies You May Encounter
| Frequency | Service | Notes |
|---|---|---|
| 127.150 MHz | Prestwick Tower (secondary) | Alternative tower frequency |
| 129.700 MHz | Prestwick FBO | Fixed Base Operator for business/general aviation |
| 121.500 MHz | Emergency | International emergency frequency โ never used for routine communication |
| Scottish Control (various) | Area control | Handles en-route traffic above and around Prestwick |
The Flow of Communication
Here is how a typical arriving flight moves through the frequencies:
1. En route โ the aircraft is with Scottish Control (area radar) on an en-route frequency
2. Handoff to Approach โ Scottish Control tells the pilot to contact Prestwick Approach on 120.550
3. Vectored to final โ Approach gives headings and descents to line the aircraft up with the runway
4. Handoff to Tower โ when the aircraft is established on the final approach, Approach tells the pilot to contact Prestwick Tower on 118.150
5. Landing clearance โ Tower clears the aircraft to land
6. After landing โ Tower gives taxi instructions to the stand
For a departing flight, it works in reverse: Tower for startup and taxi, Tower for takeoff clearance, then a handoff to Approach or directly to Scottish Control.
Listening In
If you want to listen to Prestwick ATC, you have several options:
- Airband scanner โ a handheld radio receiver that covers the aviation VHF band (118-137 MHz). Legal to own and listen to in the UK, though you should not act on or share operationally sensitive information
- Online feeds โ websites and apps like LiveATC sometimes carry Prestwick feeds
- SDR (Software Defined Radio) โ a USB dongle and free software can turn a computer into an airband receiver
Listening to ATC is one of the best ways to learn how aviation works. You will quickly start to recognise callsigns, understand the rhythm of traffic flow, and anticipate what will happen next on the airfield.
Key Takeaways
- 118.150 is the frequency to watch for runway action โ takeoffs and landings
- 120.550 is where you hear aircraft being guided towards the airport
- 121.125 is the automated weather and information broadcast
- Prestwick is relatively quiet compared to major hubs, which makes it an excellent airport for beginners learning to follow ATC communications
- The same controller may work multiple positions during quiet periods
