I can only talk from a PAX’s point of view, but I always thought the stabilizing stage is after brake release and the engines spool up, above idle but only enough for a gentle roll, and only after about 5 seconds you get that nice kick in the butt as full power is reached. Am I mistaken, is this just the engines naturally spooling up to full power, as I hear it takes about 6 secs, and has nothing to do with stabilizing?
I remember a flight with SAA from Cape Town to Johannesburg, in an A300B4, where he powered up until the overhead bins started shaking before he released the brakes, must have been heavy that day, I did see quite a few worried faces.
