All of Mobile Regional Airport — runways, frequencies, charts and live weatherWhen the KMOB tower is closed
The tower is staffed 0600-2300. Outside those hours Mobile Regional Airport has no operating control tower: it becomes a self announce field on 118.3, 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 KMOB airport page for the click sequence, and what to say on the radio.
Before taxi Mobile
- ATIS 124.75
- A recorded loop of the field's weather, active runway and any notices, updated hourly or whenever conditions change. Listen before your first call, and tell the controller which letter you have so they do not read it to you again.
- ASOS/AWOS 124.75
- 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.
- Clearance 119.85
- Clearance delivery issues your IFR clearance, and at busier fields your VFR departure instructions and squawk code. Call before you request taxi, with the ATIS letter and your intended direction of flight.
Taxi & takeoff Mobile
- Ground 121.9
- 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 118.3
- 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 Mobile
- App/Dep 118.5 (320-139 · initial contact), 121.0 (140-319)
- 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 118.3
- 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.
- UNICOM 122.95
- A ground station run by the FBO rather than the FAA, for fuel, parking and airport services. Use it for services. Where the field has no separate CTAF, the same frequency doubles as the advisory frequency.
- Flight service 122.2, 127.65 (LOW)
- Flight Service handles briefings, flight plans and en route advisories, reached here through a remote outlet. Open and close VFR flight plans, and get updated weather in the air. 1-800-WX-BRIEF reaches the same specialists from the ground.
- Emergency 121.5
- 121.5 is the international emergency and distress frequency, monitored continuously. Declare on it if you are in trouble, and monitor it as a second radio when you have one free.
