NCO.OP.111 Aerodrome operating minima — 2D and 3D approach operations Regulation (EU) 2021/2237 (a) The decision height (DH) to be used for a 3D approach operation or a 2D approach operation flown with the continuous descent final approach (CDFA) technique shall 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 minimum specified in Table 1; (4) the minimum DH specified in the AFM or equivalent document, if stated. (b) The MDH for a 2D approach operation flown without the CDFA technique shall 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 minimum specified in Table 1; or (4) the minimum MDH specified in the AFM, if stated.
