V1 and weight
Guys
As we know V1 increases with weight if not field length limited.
What if field length limited ? i have seen a book stating that in that case V1 will decrease ! is it correct ? when field length limited with higher weight which requirement is the most critical ? stopping or accelerating single engine ?
thanks

For a balanced field length, as weight increases V1 must decrease due to brake energy limits. In other words, the more weight you have, the more brake energy required to bring it to a stop within the confines of the balanced field, and hence the earlier decision required.

Both accelerate-go and accelerate-stop are equally important with regard to balanced field. Are you flying a commuter or transport category airplane? In the US, Canada or different country?
If you have a balanced field length, you are at your maximum performance limited take-off weight.
You cannot, therefore, increaes the take-off weight any further.
