Acceleration stop distance on B777 ?

[plain-plane]

EFB numbers

In my small 73, my EFB also gives me "stop margin", the calculated remaining distance of ASDA, after an RTO at V1...

Now if you are not quite happy with ASD with a zero meters margin, then you can change some of the inputs, and change your performnce to give you a better margin.... (on the EFB you can: short the runway from either end, increase the TOM by an approved amount, and a few other things)

There are often a range of V1 speeds available to you, and knowing on what criteria your company has selected for the prefered V1s on the EFB, gives you a good basis for changing the basic settings for your takeoff performance...

Ie: the EFB gives you go minded V1 speed on contaminated runways, and will generally avoid V1 speeds giving you 0 meters of stop margin...
