Do 160g Section 22

The fundamental document that defined the environment and test waveforms used in do 160 section 22 and accounted for the lightning data and analysis necessary to support these requirements is sae arp5412 aircraft lightning environment and related test waveforms originally published in 1999 and revised to revision a in 2005.

Do 160g section 22. Basic considerations rtca do 160g section 22 commercial aircraft complete set of tests included in place for a long period mil std 461g cs117 new military aircraft and surface naval ships complemented by other stds like 464 introduced in 2015 based on do 160g rtca radio technical commission for aeronautics. Rtca do 160 section 22 offers test procedures to determine whether the eut can operate as specified during and or after various lightning induced transient waveforms are injected into connector pins interconnecting cables and power leads using pin injection and or cable bundle tests. Below is a table from do 160 section 22 which describes voltage and current transient wave forms. Do 160 specifies several canonical wave forms which emulate lightning induced transients.

These test methods and procedures are provided to verify the capability of equipment to withstand a selection of test transients defined in this section which are intended to represent the induced effects of lightning. The standard defines a series of prototypical waveforms which are used to apply current and voltage to the interface pin of the unit under test.
