This rtca do-160d outlines a set of minimal standard environmental rtca do-160d 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.
The norm defines the different temperature profiles rtca do-160d which the equipment must be tested. Aircraft type dependent test checks the effects of vibration and the equipment’s ability to operate during all vibration scenarios. The DO document was first published on February 28, to specify test conditions for the design of avionics electronic hardware in airborne systems.
The power input tests simulate rtca do-160d of aircraft power from rtca do-160d engine start to after landing including rtca do-160d. These frequency components are normally harmonically related to the power source fundamental frequency. This test determines whether the equipment interconnect circuit configuration will accept a level of induced voltages caused by the installation environment.
Cover of original issue. 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.
Direct and rtca do-160d effects depending on mounting location; includes induced transients into the airframe or wire bundle. Crash safety test insures the item does not become a projectile in a crash.
Do-16d 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.
These tests subject the unit to an environment of blowing sand and dust of specific particle sizes in which the rtca do-160d must operate at the end of exposures. These tests subject the test article to various scenarios of dripping water or pooled water to verify the unit will fully operate in the given do-160c. Since then the standard has undergone subsequent revisions up through Revision G.
This checks the effects of temperature on the system.
RTCA DO Testing to DO D, E & F
The purpose of rtca do-160d tests is to provide a controlled laboratory means of assuring the performance characteristics of airborne equipment in rtca do-160d conditions similar of those which may be encountered in airborne operation of the equipment.
Views Read Edit View history. These tests subject rtca do-160d test article to an environment under vacuum, with a gaseous mixture of combustibles. Typically moisture sensitive devices have issues with this test and require conformal coat or other types of protection.
This test determines whether equipment can withstand the effects of voltage spikes arriving at the rtca do-160d on its power leads, either AC or DC. This test verifies the test articles ability to survive multiple exposures of salt fog and drying and the environment’s ability to cause accelerated corrosion. The unit must operate and be subjected to any actuation including knob turns and button pushes and not ignite the environment.
Condensation also can rtcx rtca do-160d factor coming from cold temperatures. The standard environmental test conditions and test procedures contained within the standard, may be used in conjunction with applicable ftca rtca do-160d standards, rtca do-160d a minimum specification under environmental conditions, which can ensure an adequate degree of confidence in performance during use aboard an air vehicle.
This page was last edited on 6 Mayat These tests under humidity check the rtca do-160d of high concentrations of humidity and the articles ability to withstand moisture effects. Factors tested include dielectric strengthcooling under low pressure, and resilience to rapid change in air pressure. Retrieved from ” https: This aircraft type dependent test checks the effects of mechanical shock.
DO, Environmental Conditions and Test Procedures for Airborne Equipment is a standard for the environmental testing of avionics hardware. Due rtca do-160d the variety of aircraft, the equipment are classified in categories.
The Standard Includes Sections on:. This section relates specifically to interfering signals related to the power frequency and rtca do-160d harmonics, rtca do-160d frequency signals, and electrical transients that are generated by other on-board equipment or systems and coupled to sensitive circuits eo-160d the EUT through its interconnecting wiring.
From Wikipedia, the free encyclopedia.
Aviation related fluids susceptibility including a variety of fluids ranging from carbonated sugared beverage to various cleaners and solvents. RF emission and rtca do-160d. Input power conducted emissions and susceptibility, transients, drop-outs and hold-up. 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.
