787/A380 takeoff attitude
Hi Everyone
I live *very* close to an international airport, and have noticed that the 787 and A380 are considerably quieter than the aircraft they have the potential to replace.
The difference between the 747 and the A380 in particular is really impressive.
I noticed a Virgin 787 go off yesterday, and it may be my imagination, but it seems to fly a much shallower departure very soon after lifting off.
The same goes for the A380; the 747 seems to shoot straight up, engines screaming, whereas the A380 seems to have a more sedate, leisurely sort of lumbering depature. Seems to pass by lower and much quieter.
So I assume the modern engines contribute to the lower noise levels, but are the aircraft designed/powered to the extent that they can fly "shallower" departures and require less thrust? or is it my imagination?
thanks
