Re: Pulling a Stop to Runway Overruns
Civil practice is generally straightforward enough.
You define the practice used to achieve the scheduled field performance in the manual, and describe that in the POH.
It's actually common to have aircraft where it's known that the POH scheduled performance could be improved upon - but a conscious decision was made to use a more conservative (and thus predictable) set of handling actions to safeguard the company from liability in the event that the pilot failed to take the actions exactly as the company TP had.
Incidentally, the last light aircraft I test flew (a new French model) had all three wheels braked - it was like hitting a brick wall!
