(i) at which the length of the longest runway is notified as 1850 metres or less:
(aa) subject to sub-paragraph (bb), the airspace extending from the surface to a height of 2000ft above the level of the aerodrome within the area bounded by a circle centred on the notified mid-point of the longest runway and having a radius of 2 nautical miles;
(bb) where such an aerodrome traffic zone would extend less than 1½ nautical miles beyond the end of any runway at the aerodrome and this sub-paragraph is notified as being applicable, sub-paragraph (ii) shall apply as though the length of the longest runway is notified as greater than 1850 metres;
(ii) at which the length of the longest runway is notified as greater than 1850 metres, the airspace extending from the surface to a height of 2000ft above the level of the aerodrome within the area bounded by a circle centred on the notified mid-point of the longest runway and having a radius of 2½ nautical miles;
(b) in relation to such an aerodrome which is on an offshore installation, the airspace extending from mean sea level to 2000ft above mean sea level and within 1½ nautical miles of the offshore installation;
