That took off early for a 747 on that runway o.o

Ohh ok, is that graph called a Koch Chart by chance?

Nope, its only via graph's or FMC and thephaze3 is correct, you also have to compensate for pressure altitude and temperature. The thinner the air, the more speed you need to be able to fly.

"They're on the ground, so it's ground speed". You're ignorant and rather irritating sir. thephaze3's second reply to you was perfectly reasonable you rude little prick.

Ok finally a real answer from the man himself! So you're telling me that in my game, I cant calculate V1 Vr V2 etc. ? It doesnt come with an FMC (FMS) Im not sure why, but only payware aircraft come with FMC's. So I cant calculate it?
SuredT (August 26, 2008 at 7:42 pm)
V1, Vr, V2 are airspeeds, not groundspeeds, although the aircraft is on the ground. If you have zero wind, then airspeed is the same as groundspeed. If you have 30 kts headwind you rotate at same airspeed however groundspeed is much lower (30 kts). V1, Vr, V2 speeds are based on aircraft weight, so the FMS can calculate them, or the pilot looks in a graph in the flying manual to find the correct speeds
seb13gp (August 26, 2008 at 3:23 pm)
they're on the ground, so its ground speed. ANYWAY, do you people have any idea how to calculate it or are you gonna keep giving me useless comments?

the are speaking dutch my friend!

If you're dork enough to ask about V1, Vr speeds etc then you should understand that they are in reference to the indicated airspeed - basically the speed of the airflow. |
