What is the AMC for general requirements on equipment installation under CS-23?

AMC1 23.2505 General requirements on equipment installation, based on ED Decision 2026/003/R.

What is the basis for showing compliance for electrical systems on aeroplanes with electric or hybrid-electric propulsion?

ASTM F44 published standards for showing compliance for such electrical systems, but EASA has not yet accepted F3316-19; however, EASA would consider applications using this standard as a basis for means of compliance, subject to agreement.

Which AMC and GM issues are referenced in this section?

AMC&GM to CS-23: Issue 4 and AMC&GM to CS-23: Issue 5.
