His current focus is on Electrical Wiring Interconnection Systems (EWIS) and Flammability. Petar was born in Belgrade, Serbia and has […] Read more

A new standard for EWIS design: IPC-D-620

May 19, 2015 Michael Traskos

As EWIS (Electrical Wiring Interconnection System) engineering is becoming a more mature field, additional standards and requirements are being developed. The latest of these EWIS design standards is the IPC-D-620, “Design and Critical Process Requirements for Cable and Wiring Harnesses.” This pending standard, coupled with the design requirements of IPC (Institute of Printed Circuits) documents, […] Read more

Aircraft wire inspection? Time tested guidelines

March 18, 2015 Carina Cannon

Performing routine aircraft wire systems visual inspections is a critical aspect of maintaining aircraft airworthiness and extending the component lifecycle. A visual inspection is the first step in assessing the condition of a component or determining what future steps need to be taken. This article discusses recommended techniques based on MIL-HDBK-522, which provides EWIS inspection […] Read more

Recognizing the tremendous interest in making a transition to electrical components, Lectromec attended the More Electrical Aircraft conference held in Toulouse, France, on February 3rd – 5th. This article summarizes some of the key points discussed during the conference. Read more

Principles of aircraft wiring system safety

February 11, 2015 Carina Cannon

Principles of Aircraft Wiring System Safety System safety supports risk management with the ultimate goal of optimizing safety on aircraft systems. Risk management is a vital aspect of system development that takes effect during the design phase; however it also remains important during the implementation and sustainment phases of an aircraft lifecycle. Optimizing safety is […] Read more

Electrical tests for aircraft wires and cables

January 26, 2015 Michael Traskos

Equipment installed onto aircraft goes through a range of tests designed to verify that the component meets the operational needs and environmental factors. For wires and cables, these tests include chemical exposure, thermal, mechanical, and electrical testing. We have already covered mechanical tests in our Assessment of Mechanical Stress on Wire Insulation article, as well […] Read more

What’s next for aircraft EWIS: Carbon nanotubes

December 17, 2014 Emma Schwoerer

This article describes findings from a Rice University study showing the potential for creating new products based on carbon nanotube (CNT) technology. According to the research, CNT fibers have incredible properties that make them ideal for aerospace. For example, they are much stronger and have a greater capacity for carrying current than copper cables of the same mass. Read more

MIL-HDBK-454 handbook guidelines for EWIS components

November 14, 2014 Carina Cannon

This article covers eight out of the 78 military guidelines from the General Guidelines for Electronic Equipment handbook (MIL-HDBK-454) applicable to wire system component testing, EWIS component selection, and good wiring practices. The handbook covers guidelines for the selection, handling, and application of electronic equipment on aircraft. Read more
