Re: Flaps and aborted landings/go-arounds

It is indeed.

The whole point of the "alt-go" procedure is to give us a "calmer" option compared to a standard go-around if we are above 1000 feet and not in a hurry. Level off. Take a breath. There's no rush. Everything set? Ok, "go around flaps".

Caveat: I'm not ATC.

It think it is in case the landing plane goes around and potentially impinges on the departure path. Of course, the landing plane could initiate a go-around even after touchdown, but I guess that is less likely.

It isn't because of thrust or wake turbulence.

The landing distance is indeed calculated from the threshold. And since you're nominally at 50 feet at the threshold, the ground roll is shorter than the landing distance.
