42. Mass limitation
Edition: 2018-05-11 · Repealed
42. Mass limitation
(1)The mass of the helicopter at the start of take-off shall not exceed the mass at which the code of performance referred to in these Regulations is complied with, allowing for expected reductions in mass as the flight proceeds and for such fuel jettisoning as is appropriate.(2)In no case shall the mass at the start of take-off exceed the maximum take-off mass specified in the helicopter flight manual taking into account the factors specified in Regulation 41 sub-regulation (5).(3)In no case shall the estimated mass for the expected time of landing at the destination and at any alternate exceed the maximum landing mass specified in the helicopter flight manual taking into account the factors specified in Regulation 41 sub-regulation (5).(4)In no case shall the mass at the start of take-off, or at the expected time of landing at the destination and at any alternate, exceed the relevant maximum mass at which compliance has been demonstrated with the applicable noise certification regulations in Civil Aviation (Environment Protection) Regulations unless otherwise authorized in exceptional circumstances for a certain operating site where there is no noise disturbance problem, by the competent authority of the State in which the operating site is situated.(5)In developing a code of performance, the Authority shall apply a risk assessment methodology in accordance with the guidance in the First Schedule or the standards of subregulation (6) shall apply.(6)Take-off and initial climb phase—(a)operations in performance Class 1. The helicopter shall be able, in the event of the failure of the critical engine being recognized at or before the take-off decision point, to discontinue the take-off and stop within the rejected take-off area available or, in the event of the failure of the critical engine being recognized at or after the take-off decision point, to continue the take-off, clearing all obstacles along the flight path by an adequate margin until the helicopter is in a position to comply with provisions of subregulation (7)(a);(b)operations in performance Class 2. The helicopter shall be able, in the event of the failure of the critical engine at any time after reaching DPATO, to continue the take-off, clearing all obstacles along the flight path by an adequate margin until the helicopter is in a position to comply with Before the DPATO, failure of the critical engine may cause the helicopter to force-land; therefore the conditions stated in Regulation 47(2) shall apply; and(c)operations in performance Class 3. At any point of the flight path, failure of an engine will cause the helicopter to force-land; therefore the conditions stated in regulation 47 (3) shall apply.(7)En-route phase—(a)operations in performance Classes 1 and 2. The helicopter shall be able, in the event of the failure of the critical engine at any point in the en-route phase, to continue the flight to a site at which the conditions of subregulation (7)(b) for operations in performance Class 1 or the conditions of sub regulation (8)(b) for operations in performance Class 2 can be met, without flying below the appropriate minimum flight altitude at any point;(b)operations in performance Class 3. The helicopter shall be able, with all engines operating, to continue along its intended route or planned diversions without flying at any point below the appropriate minimum flight altitude and at any point of the flight path, failure of an engine will cause the helicopter to force-land: therefore the conditions stated in regulation 40(3) shall apply.(8)Approach and landing phase-(a)operations in performance Class 1. In the event of the failure of the critical engine being recognized at any point during the approach and landing phase, before the landing decision point, the helicopter shall, at the destination and at any alternate, after clearing all obstacles in the approach path, be able to land and stop within the landing distance available or to perform a balked landing and clear all obstacles in the flight path by an adequate margin equivalent to that specified in subregulation (6)(a) and in case of the failure occurring after the landing decision point, the helicopter shall be able to land and stop within the landing distance available:(b)operations in performance Class 2. In the event of the failure of the critical engine before the DPBL, the helicopter shall, at the destination and at any alternate, after clearing all obstacles in the approach path, be able either to land and stop within the landing distance available or to perform a balked landing and clear all obstacles in the flight path by an adequate margin equivalent to that specified in subregulation (6)(b) and after the DPBL. failure of an engine may cause the helicopter to force-land; therefore the conditions stated in regulation 47(2) shall apply;(c)operations in performance Class 3. At any point of the flight path, failure of an engine will cause the helicopter to force-land; therefore the conditions stated in regulation 47(3) shall apply.
