Just been browsing this thread for the first time in a while, and noticed:
EG “Climb to 2 thousand”. (Which would require a read back.)
I'm retired from flying, but am pretty sure that this transmission would be EITHER " climb twenty-two thousand feet " (not something too many rotary drivers would expect) OR " climb two thousand feet " depending on the controllers requirements, thus avoiding ambiguity. I don't miss the "stepped-on call" experience one little bit, especially when one of the people transmitting seems to like the sound of their own voice so much that they go on... and on...
