CAT.POL.A.330 Landing — dry runways
(a)
The landing mass of the aeroplane determined in accordance with CAT.POL.A.105 (a) for the estimated time of landing at the destination aerodrome and at any alternate aerodrome shall allow a full stop landing from 50 ft above the threshold within 70 % of the LDA taking into account:
(1)
the altitude at the aerodrome;
(2)
not more than 50 % of the headwind component or not less than 150 % of the tailwind component;
(3)
the runway surface condition and the type of runway surface; and
(4)
the runway slope in the direction of landing.
(b)
For steep approach operations, the operator shall use landing distance data factored in accordance with (a) based on a screen height of less than 60 ft, but not less than 35 ft, and comply with CAT.POL.A.345.
(c)
For short landing operations, the operator shall use landing distance data factored in accordance with (a) and comply with CAT.POL.A.350.
(d)
For dispatching the aeroplane in accordance with (a) to (c), it shall be assumed that:
(1)
the aeroplane will land on the most favourable runway, in still air; and
(2)
the aeroplane will land on the runway most likely to be assigned considering the probable wind speed and direction, the ground handling characteristics of the aeroplane and other conditions such as landing aids and terrain.
(e)
If the operator is unable to comply with (d)(2) for the destination aerodrome, the aeroplane shall only be dispatched if an alternate aerodrome is designated that permits full compliance with (a) to (d).
CAT.POL.A.335 Landing — wet and contaminated runways
(a)
When the appropriate weather reports and/or forecasts indicate that the runway at the estimated time of arrival may be wet, the LDA shall be equal to or exceed the required landing distance, determined in accordance with CAT.POL.A.330, multiplied by a factor of 1.15.
(b)
When the appropriate weather reports and/or forecasts indicate that the runway at the estimated time of arrival may be contaminated, the landing distance shall not exceed the LDA. The operator shall specify in the operations manual the landing distance data to be applied.
(c)
A landing distance on a wet runway shorter than that required by (a), but not less than that required by CAT.POL.A.330 (a), may be used if the AFM includes specific additional information about landing distances on wet runways.
