BFA, I am referring to a situation where a light aircraft in front of me is late to vacate, I'm in a light aircraft as well and I'm approaching my home field which has a 2.2 km runway. There is no such thing as "min app speed" in the light aircraft I fly. There is a reference speed but in most aircraft the flaps are so effective that I can slow down from the top of the white arc to stall speed in ten seconds or so. And at my field light aircraft are sequenced so close behind each other that reducing speed does not make a difference. Landing long does buy you some time and of course if you see the situation developing early enough, that's exactly what you do. But if the landing clearance is late in coming I might already be so low that "landing long", in the sense that you alter your approach path to an aiming point further down the runway, is no longer an option. Flaring and holding off with a bit of power on is.
I would not do this at an unfamiliar field. I would not do this in an unfamiliar aircraft. I would also not do this in a gusty crosswind. But as I said in one of my posts in that other thread: it's a game you're playing. ATC knows the callsigns of the aircraft based there and sometimes tries to push things. If you're comfortable with that game, you can play along and this is one of the tricks we use. Within limits of course: a go-around should always remain a possibility.
