For instance, what about an SEP with a magnificent power/weight ratio, but only the bog standard brakes, that are fitted to most light aircraft. If it accelerates like s@#t down the runway, why is it guaranteed to stop in the same distance?

Where can I find one of these?

I think you can take it as read that on a dry, paved runway the brakes will out-perform the thrust. Were that not the case your power-checks and short-field takeoff (full power before brake release) would be "interesting" to say the least

Where this balance shifts is where the friction is reduced such as on ice or wet grass - here the thrust (unaffected by such things) may be greater than the braking ability.

These circumstances may lead to a situation where you need less distance to accelerate than you do to stop (NB remember we are talking about speeds less than "flying speed") - but that would be the exception rather than the rule.

=========================================

I found this an interesting thread, but can we play the ball, and not the man?
