I remember when I use to fly (passenger, not pilot!) from Heathrow to Manchester occasionally. The Air Stewardesses used to have to rush out with the trolley virtually before the wheels left the ground so they could finish the teas and get it locked away before the descentNot necessarily. The ideal descent into Edinburgh starts up to 150 miles away with the aim being to keep the engines idling until 1000 ft. With restrictions due to other aircraft or shortening of the route planned the ideal descent may need adjustment. With a longer route thrust must be added, but with a shorter route speedbrakes are needed to give greater drag if the aircraft is not to arrive too high or fast at the 1000 ft point.
So whilst they may be being naughty, probably you just happen to live in an area where drag is often needed on the approach.
That's such a sad photo.
I looked it up and saw this reply:What on the earth would the daily rental be on an A380 ?
