AMC4 NCC.OP.110 Aerodrome operating minima — general ED Decision 2022/012/R DETERMINATION OF DH/MDH FOR INSTRUMENT APPROACH OPERATIONS — AEROPLANES (a) The decision height (DH) to be used for a 3D approach operation or a 2D approach operation flown using the continuous descent final approach (CDFA) technique should not be lower than the highest of: (1) the obstacle clearance height (OCH) for the category of aircraft; (2) the published approach procedure DH or minimum descent height (MDH) where applicable; (3) the system minima specified in Table 4; (4) the minimum DH permitted for the runway specified in Table 5; or (5) the minimum DH specified in the AFM or equivalent document, if stated. (b) The MDH for a 2D approach operation flown not using the CDFA technique should not be lower than the highest of: (1) the OCH for the category of aircraft; (2) the published approach procedure MDH where applicable; (3) the system minima specified in Table 4; (4) the lowest MDH permitted for the runway specified in Table 5; or (5) the lowest MDH specified in the AFM, if stated. DETERMINATION OF DH/MDH FOR INSTRUMENT APPROACH OPERATIONS — HELICOPTERS (c) The DH or MDH should not be lower than the highest of: (1) the OCH for the category of aircraft used; (2) the published approach procedure DH or MDH where applicable; (3) the system minima specified in Table 4; (4) the lowest DH or MDH permitted for the runway/FATO specified in Table 6 if applicable; or (5) the lowest DH or MDH specified in the AFM, if stated.
