CHAPTER 25 LANDING PERFORMANCE
25.01 Purpose
For subregulation 91.800 (2), this Chapter prescribes requirements relating to landing performance for a flight of an aircraft.
25.02 Landing performance for aeroplanes
(1) The pilot in command of an aeroplane during approach and landing must ensure that, from the time the aeroplane descends below the minimum height for the flight in accordance with regulation 91.265, 91.267, 91.277 or 91.305 (as applicable), the aeroplane has the performance to clear all obstacles by a safe margin.
(2) For subsection (1), the pilot in command must determine the performance of the aeroplane from any 1 of the following:
(a) the landing distance available;
(b) the pressure altitude and temperature;
(c) the gradient of the runway in the direction of the landing;
(d) the wind direction, speed and characteristics;
(e) the landing weather forecast;
(f) the obstacles in the approach flight path and missed approach flight path.
25.03 Landing performance rotorcraft — general
(1) The pilot in command of a rotorcraft during approach and landing must ensure that, from the time the rotorcraft descends below the minimum height for the flight in accordance with regulation 91.265, 91.267, 91.277 or 91.305 (as applicable), the rotorcraft has the performance to clear all obstacles by a safe margin.
(2) For subsection (1), the pilot in command must determine the performance of the rotorcraft from any 1 of the following:
(a) the FATO distance available;
(b) the adequacy of the size of the planned destination aerodromes and any alternate aerodromes;
(c) the pressure altitude and temperature;
(d) the gradient of the approach and any missed approach;
(e) either:
(i) the wind direction, speed and characteristics — if known; or
(ii) zero wind — if the matters mentioned in subparagraph (i) are unknown;
(f) the en route and destination weather forecast;
(g) the obstacles in the vicinity of the approach flight path and the missed approach flight path.
25.04 Landing performance for rotorcraft — Category A rotorcraft within a populous area
(a) is a Category A rotorcraft which is not being operated in accordance with its category B supplement in the AFM (the rotorcraft); and
(2) The pilot in command of the rotorcraft may land at the relevant HLS only if:
(a) the performance of the rotorcraft is sufficient to comply with the Category A procedure for landing and missed approach at the relevant HLS; and
