One more related question here...
Having read thorouly about V1,V2 etc..I have remembered that if the Balance field available is greater than the Balance field required,a RANGE of V1 is possible,to be between VGO and VSTOP.
VSTOP being the LAST speed at which one cqn stop the A/C within the TODA,if V1 is BEFORE VSTOP...isnt the difference in speed between the two an extra margin to stop after an engine failure?I can understand the margin to be only a few knots.
Also,if slush at the end of the runway,a smaller V1 is given.
How can a pilot know how these V1 speed have been calculated??
Thank you again,
