CIRCLING OPERATIONS — AEROPLANES

(a) Circling minima The following standards should apply for establishing circling minima for operations with aeroplanes:

(1) the MDH for circling operation should not be lower than the highest of:

(i) the published circling OCH for the aeroplane category;
(ii) the minimum circling height derived from Table 7; or
(iii) the DH/MDH of the preceding instrument approach procedure;

(2) the MDA for circling should be calculated by adding the published aerodrome elevation to the MDH, as determined by (a)(1); and

(3) the minimum visibility for circling should be the highest of:

(i) the circling visibility for the aeroplane category, if published;
(ii) the minimum visibility derived from Table 7; or
(iii) the RVR/CMV derived from Tables 5 and 6.A for the preceding instrument approach procedure.
