Dutch, German, French and Belgian ATPL questions and courses, Delft Technical University Performance course, that dates from AFTER WW II.
It occurs to me that the RAF had a simplified system for easy decision making. In practice this means that they used the definition in another context then the one it was established in the first place.
Balanced means that TOD=ASD whatever amount of runway remains ahead of you does not change the fact that the take off is balanced.
\'Balanced Field\' graphs were used by the RAF V bombers. They didn\'t have regulated take-off graphs for all the runways they used so they carried graphs for \'standard\' airfields
It\'s RTOW charts we are talking about, there fore your arguments altough valid in practical terms to avoid a take off beyond the limits are not valid in the context of this discussion.
