Maybe the way to think about this is how it would affect the analysis of
an accident. Suppose you flew into a mountain, the question would be
whether you had your altimiter set correctly. So they play back the
tapes and found that you readback the setting -- that takes the controller
off the hook because he got the message through to you. Otherwise,
somebody my try to say the controller should have tried one more time...


The controller is off any hook if he issued the altimeter, a readback or
lack of one changes nothing.
