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.

EASA Aerodrome Operating Minima: Approach operations' decision height (DH) or minimum descent height (MDH) must consider obstacle clearance, published procedures, system minima (like ILS 200ft, NDB 350ft), and aircraft flight manual limitations. The highest value among these factors dictates the lowest permissible DH/MDH for safe landings.
