MOC 1 VTOL.2500(b) Intended function of systems and equipment n/a **1. Considerations on Safety Assessment and Development Assurance** (a) Compliance with [VTOL.2500](#_DxCrossRefBm1877490409)(b) is intrinsically linked with [VTOL.2510](#_DxCrossRefBm1877490363) and should therefore be addressed simultaneously. (b) In particular, the safety assessment and development assurance processes described in paragraph §9 and §10 of [MOC VTOL.2510](#_DxCrossRefBm1877490370) are part of the accepted means of compliance with [VTOL.2500](#_DxCrossRefBm1877490409)(b). **2. Operating and environmental conditions** [VTOL.2500](#_DxCrossRefBm1877490409)(b) covers the equipment and systems installed to meet a regulatory requirement, or whose improper functioning would lead to a hazard. Such systems and equipment are required to “be designed and installed so that they perform their intended function throughout the operating and environmental limits for which the aircraft is certified”. The aircraft operating and environmental conditions include: (c) the full normal envelope of the aircraft, as defined by the Aircraft Flight Manual, with any modification to that envelope associated with abnormal or emergency procedures; (d) any anticipated external aircraft environmental conditions: (1) external environmental conditions such as atmospheric turbulence, HIRF, lightning, and precipitation, which the aircraft is reasonably expected to encounter, with severities limited to those established by certification standards and precedence; (e) any anticipated internal aircraft environmental conditions: (1) the environmental effects within the aircraft, including vibration and acceleration loads, variations in fluid pressure and electrical power, and fluid or vapour contamination due to either the normal environment or accidental leaks or spillage and handling by personnel; and (f) any additional conditions where equipment and systems are assumed to “perform their intended function.” For lift/thrust system, compliance with [VTOL.2400](#_DxCrossRefBm1877490539) can be used to support the compliance demonstration with [VTOL.2500](#_DxCrossRefBm1877490409)(b) regarding the Electric Hybrid Propulsion System (EHPS) scope defined in the Special Condition E-19 EHPS.
