If you watched the video on Flap extension, you will no doubt be keen to see the flap retraction sequence. For retraction, the trailing edge flaps retract first until Flap 5 is selected when the outboard variable camber flaps retract. The mid-span variable camber and the Krueger flaps then retract on selection of flap ‘UP’ position. There you have it! Flap retraction on the B747-400ERF. Hope you like it. Later!...
