Actually John B brought forward first the word "face". I had suggested possibly something more known as "leading edge", despite that I would personally prefer "face".
I personnaly prefer: "face" as stated by J. Mitchell. Phonetics are very important as mentioned by: J. Barresi, but in my little experience with team flying, I suggest to the pilot leaders to SPEAK OUT LOUD... man...I am not only going deaf, but if you speak the commands for yourself, only, then the other pilots will be half way guessing...??? Huu me and my big mouth... Nothing personal Jim F.-....dig.
(I guess my best position would be next to the pilot leader, that way, I CAN HEEEAR YOUUU...)
As for leading a team, I would also be to soft spoken for doing that.
