assistant: Sounds logical - but I've never heard the term used during my
   5000 hours of military flying. That's not to say that it wasn't
   used, just that I never heard it used.
   Funny thing - you're familiar with the terms "Roger" and
   "Wilco"? We were taught that "Roger" simply means something
   like, "Yeah, Center, I heard you" <g>
   And "Wilco" is short for Will Comply.
   Remember Andy Griffith commenting about that fellow,
   "Roger Wilco"?
   To my surprise, after graduating from Aviation Cadets in 1955,
   I never heard the term "Wilco" used. Everyone just replied,
   "Roger" when given an instruction by some controlling agency.
   I used to use the term, and always felt kinda "corny" when
   I did so, and I always expected some of my fellow pilots to
   give me a hard time about it, but they never did.
   Pilots like to be individualists, and do their own thing.
   We used to have one that always said, "Roger that". It
   drove our Commander nuts, and he finally clamped down on
   that usage.
    I'm not familiar with the 'merging plots'.
    I think you have the right idea. A flight of 4 in formation
    would be responsible for their own separation, but they might
    also be under ARTCC control.
    We used to do Air-to-Air refueling, and our GCI site would
    handle the join ups with the tanker. Center would turn over
    a block of airspace, and a working area, to the GCI site.
    The Letters of Agreement between GCI and ARTCC would contain
    the acronym 'MARSA'; but I don't ever recall hearing the term
    used, verbally, in the pilot-to-ground communications.
    GCI had the responsibility for keeping us in the working area,
    and the pilots had the responsibility for staying within the
    assigned altitude block.
