Excuse me for returning to a point that the subscribers of high speed gave up on a while ago.
Peoples arguments that 250 below FL100 doesn´t take much longer than 300, hang their hats on a 30-35 mile straight in. I agree, in that case the savings are negligable. But I do an awful lot of approaches where we have to be at FL 100 with more than 60 trackmiles. Sometimes much more! So I haven´t quite given up on the good sense in keeping speed high if allowed.
People are talking rushed approaches and being high, with unnecessary go arounds to follow. Sure, don´t get pulled into something that you´re not comfortable with. But I´m talking well planned and excecuted highspeed approaches. They can give our pax and my conx times, just those extra few minutes that they need. Sometimes it doesn´t matter, sometimes it helps a lot. And with our company 1000-1100 flights a day, a few minutes here and there, CAN count.
