Do any Boeing 707 pilots or former 707 pilots know if it was usual to use a flaps 40 setting for landing or whether flaps 50 was the preferred setting. I would imagine, although I could be wrong, that flaps 50 in the various models of the Boeing 707 created more noise and higher fuel burn.
I know for talking to pilots of other types of jetliners that the final landing flap setting could depend on things such as wind and other factors. Not sure if this would be true of the Boeing 707 jetliner.
Second, but related question for 707 pilots: Could one go from flaps 25 to flaps 50 without stopping first at flaps 40 or did one need to allow the aircraft to slow at flaps 40 before it was safe to lower the flaps to the 50 setting?
Thanks so much for any information.
