What is the minimum MDH for a circling approach with a Category C aeroplane under NCC.OP.112?

600 ft, as specified in Table 1 for aeroplane category C.

For a circling approach with a Category B aeroplane, what is the minimum visibility required by Table 1?

1600 m, as specified in Table 1 for aeroplane category B.

If the published circling OCH for a Category D aeroplane is 650 ft and the preceding IAP has a DH of 500 ft, what is the minimum MDH for the circling approach?

700 ft, because the MDH must be the highest of the published circling OCH (650 ft), the Table 1 value for Category D (700 ft), and the preceding IAP DH (500 ft).

For a circling approach with a Category A aeroplane, if the published circling visibility is 2000 m, what minimum visibility must be applied?

2000 m, because the minimum visibility is the highest of the published circling visibility (2000 m) and the Table 1 value for Category A (1500 m).

What is the minimum circling height for a Category B aeroplane according to Table 1?

500 ft, as specified in Table 1 for aeroplane category B.

Under NCC.OP.112, what is the minimum visibility for a circling approach with a Category D aeroplane if no circling visibility is published?

3600 m, as derived from Table 1 for aeroplane category D.

NCC.OP.112 Aerodrome operating minima -- circling operations with aeroplanes

Q: When determining the MDH for a circling approach, which three values must be compared, and which one is selected?

The MDH must not be lower than the highest of: (1) the published circling OCH for the aeroplane category, (2) the minimum circling height from Table 1, and (3) the DH/MDH of the preceding IAP.
