I am curious about the phrase "around the horn." I have heard and read many references to this term in the context of engine starts, flameouts, re-lights, etc., but I have never found a good explanation of precisely what it means.
I was thinking perhaps the "horn" is some kind of detent commonly found on jet throttles, or maybe an engine instrument indication of some kind. Can anyone shed some light on this for me? Many thanks in advance. Apologies if this is more properly discussed in Tech-ops; I wasn't sure.
That's basically what it is. On the F-14 throttle quadrant there's a stop in front of the cutout position. When starting the engines you push the throttle outboard, forward then back inboard again to the idle position. Hence the term "around the horn" since the stop kind of looks like a horn. Kind of.

We've always called it 'going over the hump' from cut-off then back against the idle stop after lifting a lockout with your forefinger, like LMP737 described. Our engine runners and pilots generally call it out during engine start, and use that as a time hack for starter cut-out, light-off etc.
Ive got some experience with similar sorts of systems with 'soft detents' (my words) for afterburner engagement as well.
We used the same terminology back in the F-111 days too, though the it was the top portion of the throttle that you had to lift up to get from cutoff to idle.
Watching nugget F-18 pilots land on the boat was always fun. They would get a death grip on the trottle and go right through the mil stop into burner. The Hornt would be sitting there in the wire in full burner.
