Remarks
— F3061/F3061M-24a Standard Specification for Systems and Equipment in Small Aircraft
At variance with F3061-24a, paragraph 4.4.2, use of system level verification is usually not acceptable, and it should be discussed with EASA.
— F3532-25 Standard Practice for Protection of Aircraft Systems from Intentional Unauthorized Electronic Interactions
At variance with F3532 and F3061-24a, paragraph 4.3, for showing compliance with CS 23.2500(b) for equipment and systems whose improper functioning could lead to an intentional unauthorised electronic interaction (IUEI)
— For an aeroplane with assessment level IV, the applicant may consider AMC 20-42.
— For an aeroplane with assessment level I, level II or level III, the applicant may consider ASTM F3532-25.
For an aeroplane with certification level 1, operated in visual flight rules (VFR) day or night, considerations of cybersecurity threats as potential sources of improper functioning of the equipment and systems are not required.
ASTM F44 published standards for showing compliance for electrical systems that are installed on aeroplanes with electric or hybrid-electric propulsion systems. EASA has not yet accepted F3316-19; however, EASA would take into consideration applications from applicants that use this standard as the basis for the development of their means of compliance subject to agreement with EASA.
