Rule 17 (7):
(c) Where take-offs and landings are not confined to a runway:
(i) a flying machine or glider when landing shall leave clear on its left any aircraft which has landed or is already landing or about to take off;if such a flying machine or glider is about to turn it shall turn to the left after the commander of the aircraft has satisfied himself that such action will not interfere with other traffic movements;and
(ii) a flying machine about to take off shall take up position and manoeuvre in such a way as to leave clear on its left any aircraft which has already taken off or is about to take off.
