I completely agree, radio skills are one area that a lot of new guy's will probably struggle in. However, i feel like the airline who is training said new guy should do a better job teaching radio etiquette during the training process. I feel like radio skills are only acquired through a good cfi, and i was fortunate to have one that insisted we fly in high traffic areas where ATC communication was 100% nessacary. That is how i learned, but not all cfi's are like that. So while i agree that radio skills need to be seriously improved upon, I think that standardization of ATC skills should be a part of 121 ground school. If we are being examined in every other aspect of our pilotage skills, the radio should not be left out. Thats pretty scary that the first time real radio skills are used is during IOE, and I can see why that would make a captain nervous.
