Before taxi Modesto
- ATIS 127.7
- 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 127.7
- 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 Modesto
- Ground 121.7
- 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 125.3
- 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 Norcal
- Departure 120.95 (060-205 MOD), 123.85 (WEST), 125.1 (NORTH)
- Departure control is the radar facility working aircraft climbing out of the area. Tower hands you off after takeoff. Check in with your altitude leaving and your assigned altitude.
Arrival Norcal
- Approach 120.95
- Approach control is the radar facility sequencing arrivals into the area. Call inbound for flight following or an instrument approach, with your position, altitude and request.
Also
- CTAF 125.3
- 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.
