Capt.Doug,

OK, so should I say something like "leaving FL290 for 12000 at CLARR,"
assuming I'm already cleared to descend at my discretion?

Sounds professional.


Actually, no, it doesn't. The word "for" is to be avoided because it sound
the same as "four". It sounds like many airline pilots (just like "twelve
hundred" or "with you"), but professional it is not.
