• ED Decision 2003/2/RM found in: CS-25 Amdt 27 - Large Aeroplanes (Jan 2023)

CS 25.1363 Electrical system tests ED Decision 2003/2/RM (See [AMC 25.1363](#_DxCrossRefBm1709821680)) (a) Tests must be made to determine that the performance of the electrical supply systems meets the requirements of this CS-25 under all the appropriate normal and failure conditions. When laboratory tests of the electrical system are conducted – (1) The tests must be performed on a mock-up using the same generating equipment used in the aeroplane; (2) The equipment must simulate the electrical characteristics of the distribution wiring and connected loads to the extent necessary for valid test results; and (3) Laboratory generator drives must simulate the actual prime movers on the aeroplane with respect to their reaction to generator loading, including loading due to faults. (b) For each flight condition that cannot be simulated adequately in the laboratory or by ground tests on the aeroplane, flight tests must be made.
