Out-of-table CG clamped to the nearest trim value · case 03

A CG beyond the certified trim table produces a plausible-looking trim setting.

Case contract

Input {'pmac','flaps','tables':{flap string:[[%MAC, trim units] ascending]}}. Missing flap table -> 'ERR_FLAPS'; %MAC outside the table's inclusive range -> 'ERR_RANGE' (no extrapolation or clamping); otherwise linear interpolation between bracketing nodes, rounded to 0.1 unit.

Why this case matters

Takeoff stabilizer trim is read from a flap-specific table indexed by %MAC; out-of-table values must not be silently clamped.

One recorded failure
