RTCA/DO-160 Section 19: Induced Signal Susceptibility

RTCA/DO-160 Section 19 provides test procedures to determine whether the EUT can operate as required when the equipment and interconnecting cables are subjected to audio frequency electric fields, magnetic fields, and transient voltage spikes.

In RTCA/DO-160 Section 19, the test levels for interconnecting cable tests are determined by the length of wire exposed to the radiating wire. RTCA/DO-160 Section 19 states that magnetic and electric fields induced into cables, the test level is defined as the product of the length of interconnecting cable exposed to the radiating wire and the rms voltage or current applied to the wire.



Equipment

RTCA/DO-160 provides standard procedures and environmental test criteria for testing airborne equipment for the entire spectrum of aircraft from light, general aviation aircraft and helicopters through the "jumbo jets" and SST categories of aircraft. The tests outlined in this standard are performed to meet FAA and international regulations for electrical and electronic equipment installed on commercial aircraft.

RTCA/DO-160 G is the current version of this standard. Coordinated with EUROCAE, RTCA/DO-160G and EUROCAE/ED-14G are identically worded. DO-160G is recognized by the International Organization for Standardization (ISO) as de facto international standard ISO-7137.

The Equipment Categories are comprised of two characters. The first character (A, B, C, or Z) indicates the tests performed and severity level of the tests. The second character (C, N, or W) indicates the AC power system operating frequency (Constant, Narrow Variable, or Wide Variable) which the EUT is compatible with.
