Does anyone know what speed of take off the 747-400 achieves please? I do know that it differs a bit due to weather conditions but since I've been on them so many times I was getting rather interested.
True, but the pilot won't notice because he is actualy looking at the dynamic air pressure and he is supposed to rotate when the dial hits the mark which is independent of the air density. The actual groundspeed will change though and hence the T/O roll.speed depends upon air density.
Maybe things have changed more than I realized in the 29 years since I last had my mitts on a yoke. I've never heard that term.FredGarvin said:Don't forget the nasty, three H's Danger...
