Note For an aeroplane and a rotorcraft, paragraphs 91.265 (2) (b) and (3) (b), respectively, permit flight over a populous area or a public gathering below 1 000 ft above the highest feature or obstacle within a horizontal radius of 600 m or 300 m, respectively, of the point on the ground or water immediately below the aircraft.
(2) For subsection (1), the circumstances are when the following requirements are complied with:
(a) for take-off — when, from the point of lift-off, the pilot in command is conducting a climb to the planned cruising level in accordance with normal procedures for the aircraft type;
(b) for landing — when the pilot in command is conducting a continuous descent from the cruising level or circuit height to the landing threshold using rates of descent and flight manoeuvres which are normal for the aircraft type.
12.02 Minimum height rules — other areas
(1) For paragraph 91.267 (3) (a), for flight over an area other than a populous area or a public gathering, this section prescribes take-off and landing circumstances for the purposes of paragraph 91.267 (2) (b).
