Are you suggesting the FO shouldn't be adjusting radios and Navaids without running it past the captain first?
This one is relatively easy to get around. (Well I think anyway - for Boeing at least)
Boeing produced a book - (Normal Procedures part of Vol 1) - it tells you the areas of responsibility for PF and PNF. If the radios come under the PNFs responsibility then I don't really think he (if PNF is F/O) needs to request the Capts permission.
Can you imagine the flight deck.
XXX contact BNE centre 132.75. "Capt they have asked me to contact BNE centre - can I change COM1 to 132.75? "
Bwhahah.......bet you if you did that for every frequency change - you would no longer need permission!
Seriously some of you guys are so full of yourself.
Its flying a jet - it requires some common sense and a reasonable degree of intelligence. You are not launching a space shuttle. Some people are just put on this planet to make life difficult for others - must be some part of human nature or just a genuine desire to be malicious and boost ones own ego.
