DO-160 lightning testing?
The RTCA DO-160 lightning-induced transient susceptibility tests simulate lightning. The standard specifies the transients to be induced on the equipment. This tolerance is evaluated when transients applied to interconnecting cable bundles. There are a number of cable bundle tests.
What is pin injection test?
Pin injection uses a fixed energy level, calibrated before the test and applies it to each pin of your unit. The VOC represents an open circuit voltage and the ISC represents a short circuit current. The waveform generator’s amplitude is increased until an open circuit voltage at the required level is achieved.
Does 160 have indirect lightning?
DO-160 lightning induced transient susceptibility or indirect lightning is typically the most severe transient test in all of DO-160. However, cable bundle testing requires the unit to operate through the lightning strike making the unit more susceptible to failure.
Does 160 voltage spike?
The RTCA DO-160 voltage spike test determines whether equipment can withstand the effects of voltage spikes. These spikes arrive at the equipment on its power leads. This can occur via either ac or dc power. The adverse effects voltage spikes can have on equipment are numerous and range in degree of severity.
Do 160g Do section 16?
RTCA/DO-160 Section 16 tests verify whether the equipment will negatively affect the aircraft power system that would be harmful or degrade performance in other equipment. These tests cover both susceptibility (surge, dropout, frequency transients, etc.)
Can you do a 160 temperature test?
The purpose of RTCA DO-160 temperature variation testing is to determine the performance characteristics of equipment operating between high and low operating temperature extremes. It is important to note that this temperature testing is just temperature testing.
DO-178 Do Dal?
The DO-178 standards requires that all airborne software is assigned a Design Assurance Level (DAL) according to the effects of a failure condition in the system. These levels range from the lowest E ‘No Effect’ to the highest A ‘Catastrophic’.
What are the fundamentals of do-160f, 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.
What are the characters in DO-160 section 22?
RTCA/DO-160 Section 22 category designations consist of five characters that describe the pin and cable test Waveform Sets and test levels. The 3 Pin Injection test waveforms are grouped together in two Waveform Sets (A & B).
Is the RTCA / do-160f, section 22 undergone any revisions?
Over the past few years, the standard RTCA/DO-160, Section 22 has undergone multiple revisions. As a member of the Aerospace Test Industry, I regularly receive articles and news informing me of the latest changes being implemented to the standard.
Which is the de facto international standard for do-160g?
DO-160G is recognized by the International Organization for Standardization (ISO) as de facto international standard ISO-7137.
