CS 23.2515 Electrical and electronic system lightning protection ED Decision 2017/013/R For an aeroplane where the exposure to lightning is likely: (a) each electrical or electronic system that performs a function, the failure of which would prevent the continued safe flight and landing of the aeroplane, must be designed and installed such that: (1) the function at the aeroplane level is not adversely affected during and after the time the aeroplane is exposed to lightning; and (2) the system recovers normal operation of that function in a timely manner after the aeroplane is exposed to lightning unless the system’s recovery conflicts with other operational or functional requirements of the system; (b) each electrical and electronic system that performs a function, the failure of which would significantly reduce the capability of the aeroplane or the ability of the flight crew to respond to an adverse operating condition, must be designed and installed such that the system recovers normal operation of that function in a timely manner after the aeroplane is exposed to lightning.
