Condensation also can be a factor coming from cold temperatures.
Typically moisture sensitive devices have issues with this test and require conformal coat or other types of protection. The unit must operate and be subjected to any actuation including knob turns and button pushes and not ignite the environment. When installing equipment previously qualified to other environmental standards, such as MIL-STDG, the equipment must comply with applicable airworthiness requirements.
The standard environmental test conditions and test procedures contained within the standard, may be do 160g pdf download in conjunction with applicable equipment performance standards, as a minimum specification under environmental conditions, which can ensure an adequate degree do 160g pdf download confidence in performance during use aboard an air vehicle.
This request must be fully supported with a detailed similarity assessment comparing the changes from the earlier approved article to the article in the new application. Its purpose is to show compliance with certain airworthiness requirements. As per usual, it depends. This test determine performance characteristics for equipment that must operate when exposed to icing conditions that would be encountered under conditions of rapid changes in temperature, altitude and humidity.
DO, Environmental Conditions and Do 160g pdf download Procedures for Airborne Equipment is a standard for the environmental testing of avionics hardware.
RTCA/DO-160G is Latest Version for Testing of Airborne Equipment, But Not the Only Choice
Cover of original issue. The norm defines the different temperature profiles under which the equipment must be tested.
This test determines whether the equipment interconnect circuit configuration will accept a level of induced voltages caused by the 1600g environment. do 160g pdf download
Retrieved from ” https: Direct and indirect effects depending on mounting location; includes induced transients into the airframe or wire bundle. This aircraft type dependent test checks the effects do 160g pdf download mechanical shock. From Wikipedia, the free encyclopedia. RF emission and susceptibility. Since then the standard has undergone subsequent revisions up through Revision Cownload.
This checks the effects of temperature on the system. The aircraft certification office ACO may accept the data if the similarity doqnload clearly shows that the do 160g pdf download changes will not adversely affect the environmental qualification. Your email address will not be published.
Due to the variety of aircraft, the equipment are classified in do 160g pdf download. These tests subject the test do 160g pdf download to an environment under vacuum, with a gaseous mixture of combustibles. This document outlines a set of minimal standard environmental test conditions categories and corresponding test procedures for airborne equipment for the entire spectrum of aircraft from light general aviation aircraft and helicopters through the jumbo jets and supersonic transport categories of aircraft.
These tests under humidity check the effects of high concentrations of humidity and the articles ability to withstand moisture effects. Crash safety test insures the item does not become a projectile in a crash.
The applicant must also address the differences between the two test results when providing an equivalent level of safety. This test determines whether equipment can withstand the effects of voltage spikes arriving at the equipment on its power leads, either AC or DC. Views Read Edit View history. According to an Advisory Circular dated June 22, from the U. You may use DOG to do a comparison analysis to show that it provides an equivalent level of safety in the expected operating environment.
You must determine which sections and categories are applicable to your specific project. Aviation related fluids susceptibility including a variety of fluids ranging from carbonated sugared beverage to various cleaners and solvents. This section relates do 160g pdf download to interfering signals related to the power frequency and its harmonics, audio frequency signals, do 160g pdf download electrical transients that are generated by other do 160g pdf download equipment or systems and coupled to sensitive circuits within the EUT through its interconnecting wiring.
We often get the question: Aircraft type dependent test checks the effects of vibration do 160g pdf download the equipment’s ability to operate during all vibration scenarios. This tests determine whether equipment material is adversely affected by fungi under conditions favorable for their development, namely, high humidity, warm atmosphere and presence of inorganic salts.
The user of the standard must also decide interdependently of the standard, how much additional test margin to allow for uncertainty of test conditions and measurement in each test.
These tests subject the test article to various scenarios do 160g pdf download dripping water or pooled water to verify the unit will fully operate in the given condition.
