From what I understand, shutting down an engine will not be part of the onstation procedure for the MMA, when talking with the Boeing ppl.... buuttt, when you get the the Navy involved, who knows what is going to happen...
I don't think low flying is going to disappear, I routinely identified surface contacts with my MK1MOD1 eyeball ahead of the S3 operator in haze or cloudy conditions...
Flight: "Group three off the nose at 14 miles"
S3: "Where?"
Flight: "Group three off the nose at 8 miles"
S3: "Looking..."
Tacco: "S3 I put a designate on it"
S3: "No Tacco, thats contact 31, a fishing boat..."
Tacco: "Oh, you're right...."
Flight: "Group three off the nose at 3 miles"
Nav: "Flight, you got a course and speed yet?"
S3: "Don't see anything flight, are you sure?"
Flight: "Mark on top, now, now, NOW.... course 210, speed 11, insert name and nationality, and S3, that makes it 4 to 2 so far today, better have those beers ready!"
"I'm just a 3P, sorta" Dude, enjoy it while you can, I'd trade places with ya if I could... Definitely enjoy being a 2P...
