From: various places .....
DECU,

A number of boundary conditions to consider when looking at these sorts of questions.....

From where does the question arise ? (e.g. exam question, training course, idle review of a flight manual, your company's RTOW tables, etc., etc. .. are we looking at a specific aircraft, for instance ?) .. and for what conditions does the question relate ? (e.g. min speed schedule, BFL, overspeed schedule, runway parameters and condition, etc., etc.).

One of the problems with these questions is that they may presume quite specific conditions which, in turn, lead to the appropriate, but not necessarily general, answer ... and which might not be so appropriate under other conditions ... and, sometimes, one can find parts of the envelope in one AFM which might appear to contradict the conclusion for either other conditions or another aircraft.

I don't wish to be evasive, but it does help to have the whole story ....
