mmm ... wonder if I should wind up Milt to stir the pot a tad more ... ?
Alex is quite correct .. BFL charts for general TO use are about as simplified as one can get .. and still very useful for when Capt I M A Pilot finds himself caught out in the scrub ... although most operators would opt for separating the data into general ASDR and TODR (with TORR inbuilt one way or another to avoid confusing folk). This latter gives a tad better result in most cases ... and operators are always interested in a tad better payload ....
