Flap and V Speed Calculator

I usually use this but for better data (ex. landing at higher weights because that guide only has landing data for 25% load) I use aircraft specific profile guides which are available for the 777 family, A330 family, Challenger 350, A350, A380, A220, 757, MD11, and pretty much every new aircraft. They also have other helpful info about the aircraft on them. I find them simply by searching “–aircraft type— profiles.”
