Early flaps retraction by British Airways 747 /777
My apologies for this probably being in the wrong Forum or thread.
I live about 7 miles West of Kingsford Smith Intl, Sydney, OZ.
The major World airlines fly over my house as they head West. 747s and 777s belonging to the major airlines still have their flaps down as they climb out. All except for British Airways whose wings are clean by the time they reach me. Qantas and Singapore in particular are still winding them in for quite a while as they head West. The BA aircraft are noticably lower and seem to be much faster but that may be the effect of their being lower.
I always thought that there were standard operating proceedures for these types of aircraft. This isn't a complaint, just an intriguing observation, but I've been observing this for at least two years
