Please pardon my ignorance, since I haven't been to an airshow in well over a dog's year and when I did attend them I didn't have any radio gear with me....
I am wondering why so many frequencies are needed for use by the pilots during an airshow. In published lists (i.e.: March's Annual MT Air Show Guide), I see, for example in the Thunderbirds section, a frequency for use during the diamond formation. I see another for use during the Four Ship formation. And yet another for the Solo demonstations. Other demonstration teams have only one frequency listed, which makes sense to me - having all the pilots up in the air at one time being able to talk to one another if need be. With all that I imagine the pilots have to contend with up in the air, it doesn't sound too safe to me for the pilots to have to be fumbling around with the radio to change channels between demonstations - even if it is just the punch of a button. Am I missing something in understanding how these channels are used among the planes in the sky?
