GM2 NCO.OP.112 Aerodrome operating minima — circling operations with aeroplanes

ED Decision 2022/012/R

DH/MDH — CALCULATION OF DA/MDA

NCO.OP.112 refers to MDH because the rule compares heights with other heights (minimum circling height, OCH, etc.). Usually, the MDH will be converted to MDA for operational use by adding the aerodrome elevation.
