(1)Subject to subregulation (3), no person shall dispatch or conduct a take-off in an aeroplane unless —
(a)the mass of the aeroplane on landing at the destination aerodrome will allow a full-stop landing—
(i)in the case of a turbojet- or turbofan-powered aeroplane, within 60 per cent of the landing distance available (LDA), or
(ii)in the case of a propeller-driven aeroplane, within 70 per cent of the landing distance available (LDA); and
(b)the mass of the aeroplane on landing at the alternate aerodrome will allow a full-stop landing—
(i)in the case of a turbojet- or turbofan-powered aeroplane, within 60 per cent of the landing distance available (LOA), and
(ii)in the case of a propeller-driven aeroplane, within 70 per cent of the landing distance available (LOA).

 

(2)In determining whether an aeroplane can be dispatched or a take-off can be conducted in accordance with subregulation (1), the following shall be taken into account—
(a)the pressure altitude at the destination aerodrome and at the alternate aerodrome;
(b)not more than 50 per cent of the reported headwind component or not less than 150 per cent of the reported tailwind component may be used in computing distances for take-off or landing; and
(c)that the aeroplane must be landed on a suitable runway, considering the wind speed and direction, the ground handling characteristics of the aeroplane and other conditions such as landing aids and terrain.

 

(3)Where conditions at the destination aerodrome at the time of take-off do not permit compliance with subregulation (2)(c), an aeroplane may be dispatched and a take-off conducted if the alternate aerodrome designated in the OFP permits, at the time of take-off, compliance with subregulations (1)(b) and (2).

 

(4)Where the aerodrome of intended landing has in place noise criteria that may require a landing mass reduction, the take off mass shall be adjusted to comply with such limitations.
