Will no doubt fly one next week .
Why would TC be too busy at that time of the morning it is normally vectors to a long final for the 27s .
the RNAV app would mean more track miles at this time of the day but if it pays the way for this a busier times then I'm for it .
The problem early in the morning is that you are given decent clearance which puts you on the G/S . You therefore have to slow down way out or use speedbrake which is very noisy .
What would be great would be descent to 3000 ' at 20nm so you could keep 300kts then slow down thrust levers closed to 180 kts at 10 nm and hit the glide . Quiet and efficient but perhaps not all within CAS .
Perhaps not possible but that would be the ideal from a 744 point of view .
