All of Bolton Field — runways, frequencies, charts and live weatherWhen the KTZR tower is closed
The tower is staffed 0730-1930. Outside those hours Bolton Field has no operating control tower: it becomes a self announce field on 128.1, and separation from other traffic is yours, not a controller's. Report your position and intentions on entry and on each leg of the pattern.
Runway lighting is often pilot controlled once the tower closes — check the KTZR airport page for the click sequence, and what to say on the radio.
Before taxi Bolton
- ASOS/AWOS 135.925
- An automated weather station reading the field conditions aloud — wind, visibility, ceiling, temperature and altimeter. It replaces ATIS at a field with no controller to record one. Get the altimeter setting before you descend below the transition altitude.
Taxi & takeoff Bolton
- Ground 121.8
- Ground control owns every taxiway and inactive runway on the field. Call for taxi with your position and destination on the field. You need an explicit clearance to cross any runway, including one that is not in use.
- Tower 128.1
- Tower owns the active runways and the surrounding surface area. Call before entering the surface area inbound, and hold short until you are cleared to take off or to cross.
Departure & arrival Columbus
- App/Dep 132.3 (100-279 · secondary), 134.0 (initial contact)
- One radar controller working both arrivals and departures — normal at a smaller TRACON. The same frequency takes your climb out and your inbound call.
Also
- CTAF 128.1
- The common frequency pilots use to announce themselves to each other at a field with no operating control tower. Nobody is controlling traffic — you are self announcing. Report your position and intentions on entry and on each leg of the pattern, and listen well before you transmit.
