What is the impact of increased electrical loads on aircraft wire systems?

Michael Traskos
With More Electric Aircraft (MEA) being the big push in the industry, it is important to take a moment and think about the wiring system that is going to be supporting these new designs. The following are some of the consequences resulting from an increased electrical load on the aircraft wire system: How much wire […] Read more

Where can I get aircraft wire and cable tested?

Michael Traskos
This is a common question for aerospace engineers who are working with the Electrical Wiring Interconnect System (EWIS) as well as aerospace Maintenance Repair and Operations (MRO) professionals. Basically, if you have an EWIS component that needs to be tested, you can either test it yourself or contract with an aerospace wire testing organization. However, […] Read more

Aircraft wiring, nanotubes, and much more with George Slenski

John Gilroy
Today’s interview is with George Slenski, a senior electrical and electronic materials consultant. The term “subject matter expert” is thrown about casually these days. However, every now and then one encounters a person who can make the claim of deep and thorough knowledge of an area of study. George certainly fits the bill of an […] Read more

5 takeaways on aircraft wiring from a recent SAE committee meeting

Michael Traskos
The three-day SAE 8A (Wire Installation) & SAE 8D (Wire and Cable) committee meeting was held in Melbourne, Florida on the famous Space Coast. The focus of the meeting was aircraft wiring. It was collocated with the AE-7 power committee and the solid state power control/switching committee (AE-8B) to promote intercommunication between the areas of […] Read more

Life prediction of aircraft EWIS components

Michael Traskos
Aircraft vehicle reliability rests on well-designed components maintaining full functionality through the entire life cycle, or at the very least, maintaining full functionality until a predictable life limit is reached so that sustainment activities can be performed. Selection of wires and EWIS components is no different. The selection process starts with the functional requirements (electrical […] Read more

Aircraft circuit protection: A review of 5 technologies

Michael Traskos
Two weeks ago we posted a blog on the selection process for circuit protection/wire pairs. Today, we produce a grid to help you understand common aircraft circuit protection types that can be found on aircraft. The five device types talked about here are the thermal circuit protection, fuse, magnetic circuit protection, Arc Fault Circuit Breaker […] Read more

Arc flash assessment on naval vessels

Lectromec Team
Arc flash is a problem for many industries; with increased demand for electrical power, arc flash is the likely consequence. To combat this growing hazard, most organizations have taken proactive measures to provide training to their staff in the proper way to protect against an arc flash. This training is the first line of defense in protecting […] Read more

EWIS evaluation of F-16

Michael Traskos
You may ask about EWIS evaluation of aircraft of a F-16. The results of recent testing indicated a rate of 5.4 breaches per 1000 feet of wire tested. Lectromec and InterConnect Wiring, at the 10th Aging Aircraft Conference, delivered a report describing a recently completed series of tests to evaluate the status of wire harnesses removed […] Read more

Testing and Qualification of Fuses

Michael Traskos
Aircraft electrical fuse testing includes electrical, mechanical, chemical, and thermal conditions that are representative of the aircraft in question. This article discusses the basics of electrical fuses and how they are qualified for aerospace use. Read more
