Case contract

Input [weight lb, CG in, 'normal'|'utility']. Below 1500 lb -> 'ERR_BELOW_EMPTY'. Max weight 2550 normal / 2200 utility -> 'OVERWEIGHT' first. Forward limit 35.0 in up to 1950 lb then linear to 41.0 in at 2550 lb; aft limit 47.3 normal / 40.5 utility. Limits inclusive; else 'FWD','AFT','IN'.

Why this case matters

A category-dependent CG envelope with a sloped forward boundary; limit lines are part of the approved envelope.

One recorded failure
