Electronic Components Capability
The electronic components have been tested to meet environmental requirements as
specified in RTCA 160 C/D. The following information is to assist the engine installer.
To show that the ECU is not susceptible to failure when exposed to external electrical or
environmental effects, a number of tests were performed.
