When the KHSA tower is closed

The tower is staffed 0700-2100. Outside those hours Stennis International Airport has no operating control tower: it becomes a self announce field on 127.15, 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 KHSA airport page for the click sequence, and what to say on the radio.

Before taxi Stennis

ASOS/AWOS 118.375
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 Stennis

Ground 121.725
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 127.15
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 Gulfport

App/Dep 124.6 (130-309), 127.5 (310-129)
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 127.15
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 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.
