PilotEdge Forums

Hello, I was wondering if anyone new why the socal freq for socal approach around the john Wayne are different then the real worlds? Pilot edges freq is 127.20 and the real worlds is 125.35, is there a reason why its different? I was only confused because Fullerton is my home airport.

Many of the frequencies are combined on PE so you can hear more aircraft. In the real Socal, there are hundreds of different frequencies. On PE, all of those real frequencies will work and will be routed to the correct controller, but you should always use the frequency you are issued on PE to enhance your chances of hearing other traffic. If you're calling up Approach out of the blue, you can use any frequency that you can find on a chart and then ATC will direct you elsewhere if necessary.

Regarding the combining of frequencies, 127.20 is actually used in the area, but not specifically out of Fullerton. As Kevin said, we have combined several of the sectors in each area into a single sector, hence, you might end up on a different frequency than you might have in the real world. If you cold call on 125.35, though, you will be speaking to the controller who works the area around FUL, SNA, & LGB. He/she is then likely to say, "change to my frequency, 127.20."

Out of curiosity, was a specific method employed to determine which frequencies where combined and which frequency was chosen as the primary for an area?

I think an effort was made to use the approach or departure freq associated with the primary airport for the area, but I don't recall the specifics.
