AS Heathrow Director points out these manouvers must be less common due improved climb performance.
I was in Beijing in late 1990s and on an AF 747 100/200 routing Beijing -CDG we did the 360 turn -left after take off -and completed a sweeping climbing turn to pass back overhead the field at I guess about 3000-4000 feet. Thiswas because there are serious mountains(capped by THE WALL) north of Beijing and with the runways oriented north and south that was how they got the heavies over the wall.
Quite a spectacular manouver when on board
However 8 months later its a 747-400 and we just climb straight on out.
