Before taxi Sparta/Mc Coy
- ASOS/AWOS 119.775
- 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 Sparta/Mc Coy
- Ground 123.625
- 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 124.6
- 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 Volk
- App/Dep 135.25
- 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 124.6
- 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.
- Flight service 133.3 (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.
