Your question doesn't make sense, we operate a LOT of FAR25 aircraft, some with a MTOW of 16,000 lbs and others with about 870,000 lbs. Almost all of these use Balanced Field takeoff calculations. It is very easy to get a Balanced Field Length Required which is 300-400 feet less than the Available Runway Length. So what's the issue.
As for the second question, where do you get the idea that
your balanced field isn't even on the runway, and extends into the weeds somewhere. Do you understand the concept of DERATE at all? Do you know the difference between calculating a takeoff at 40C OAT or assuming that the temperature is 40C?
You need to jumpseat from somewhere in a 747 classic when it really is Field Length Limited, especially if the clearway is used
You might end up having a different perspective on things
J_T....
with tiger country in the overrun ?... So true, I wonder how many pilots know what lies right at the end of the runway, case in point look at Surabaya Indonesia, nothing on the airport charts shows that there are massive drainage ditches off the end of both runways, large enough to take your undercarriage off
