Is there a line in the config file that can be modified to make the distance to arrival airport less when asked by center to contact approach. When using the default ATC you will be asked to contact approach and many times you are not close enough to the airport for the frequency to show the arrival airport. If you tune the requested frequency you get a closer airport sharing the same approach frequency. I have been just ignoring the request until close enough the autotune for approach will give the arrival airport but there must be a setting that could be altered to allow this frequency change request to occur when closer to the airfield.Any help is much appreciated.Zane

yes. There's a cfg file that c4to creates on installation. The read me file explains it.tony

Thanks Tony,C4TO is working fine. My question regards the default ATC which I will still use for some flights. If anyone knows how to make the handoff to approach to occur at a closer distance, please let me know.Zane
