The OP asked a reasonable question, couched in explicit terms. He got a few valid answers. But Amadeus, you waded in with a non sequitur and have since compounded it by persisting. Unless you are a total retard, or have never operated in uncontrolled airspace, you know perfectly well from reading the first post that the pilot would be transmitting his intentions on the local frequency, ie 'nominating' the altitude he is climbing to on his missed approach. He is not obligated to send this message in triplicate to ICAO in Montreal or Geneva or wherever they are convening this week. Once you have found the definition of 'nominate' go to 'uncontrolled'. Stuff me.....
Normally I would not play the man, only the subject. But I have to say you would make a great check captain with Anal Airlines.
