POSITION TRANSDUCERS TESTED TO DO-160D / ED-14D
Rugged Designs Tested To Rigorous Specification
PALMDALE, CALIFORNIA USA -- Continuing to offer proven sensor solutions for commercial aircraft, SpaceAge Control successfully completed testing of its miniature position transducer products to requirements spelled out in the DO-160D document (Environmental Conditions and Test Procedures for Airborne Equipment). The 16-phase test suite was designed to verify that the position transducers can be used inside and outside the aircraft's pressure vessel. The testing gives airlines, systems integrators, avionics firms, and related organizations test data to use in the design of aircraft sensor systems for flight data recorder, flight test, aircraft modification, and similar uses.
The test suite was conducted at Garwood Laboratories, Inc. of Pico Rivera, California over a 90-day period. Over 1200 man-hours went into the development and implementation of the test suite. Development activities included in-house production of test fixtures, actuation devices, and data acquisition systems.
Published by RTCA, Inc., DO-160D has 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 document includes 25 Sections and three Appendices. Examples of tests covered include vibration, shock, waterproofness, fluids susceptibility, magnetic effect, temperature exposure, and explosive atmosphere. Coordinated with EUROCAE, RTCA/DO-160D and EUROCAE/ED-14D are identically worded.
DO-160D is recognized by the International Organization for Standardization (ISO) as de facto international standard ISO-7137. For more information on DO-160D, contact RTCA
