How must a power system be designed to handle failures or malfunctions?

The power generation, storage, and distribution system must be designed and installed to ensure that no single failure or malfunction will prevent the system from supplying the essential loads required for continued safe flight and landing.

Under what operating conditions must a power system supply connected loads?

The power generation, storage, and distribution system must be designed and installed to supply the power required for operation of connected loads during all intended operating conditions.

What is the applicability date of CS 23.2525?

The section text does not state an applicability date; it only references ED Decision 2017/013/R. Therefore, no applicability date is provided in the section.

CS 23.2525 System power generation, storage, and distribution

Q: What are the design and installation requirements for power generation, storage, and distribution systems under CS 23.2525?

Under CS 23.2525, the power generation, storage, and distribution for any system must be designed and installed to: (a) supply the power required for operation of connected loads during all intended operating conditions; (b) ensure no single failure or malfunction will prevent the system from supplying the essential loads required for continued safe flight and landing; and (c) have enough capacity, if the primary source fails, to supply essential loads, including non-continuous essential loads for the time needed to complete the function, required for safe flight and landing.

Q: What capacity is required for a power system if the primary source fails?

If the primary source fails, the system must have enough capacity to supply essential loads, including non-continuous essential loads, for the time needed to complete the function required for safe flight and landing.

Q: Does CS 23.2525 require that a single failure cannot prevent supply of essential loads?

Yes, CS 23.2525(b) requires that no single failure or malfunction will prevent the system from supplying the essential loads required for continued safe flight and landing.
