What does EWIS mean?

Posted by Clare McGarrey on June 18, 2019

In the aviation industry, we sure LOVE using acronyms. It doesn’t matter if the aircraft is for military or commercial application, we LOVE our acronyms. Lately, I have noticed more and more references to the acronym EWIS. So, what does EWIS mean? EWIS is an acronym for Electrical Wiring InterConnect System or Electrical Wiring InterConnection … Continue reading “What does EWIS mean?”

Is a Wire Termination the Same for Commercial and Defense Aircraft Wiring Harnesses?

Posted by Clare McGarrey on May 7, 2019

InterConnect Wiring must perform hundreds of wire terminations daily. A wire termination is the practice of ending a transmission line with a device, such as a contact (that will be inserted into a connector) or a terminal. There are many types of terminations in the aircraft industry, but the majority for commercial and defense aircraft … Continue reading “Is a Wire Termination the Same for Commercial and Defense Aircraft Wiring Harnesses?”

This eBook is the 8th in a series developed by InterConnect Wiring. It aims to provide engineering and technical personnel unfamiliar with wiring harness design insight into some of the process steps required to design an Electrical Wiring Interconnect System (EWIS) for combat aircraft such as the F-15 or F-16 as well as air vehicles … Continue reading “InterConnect Releases New Electrical Wiring Engineering Design eBook!”

Aircraft Plugs and Receptacle Connectors Are Just Like Legos – Here’s Why

Posted by Clare McGarrey on April 9, 2019

As I was helping my son put together the huge Harry Potter Lego Set he saved up for with his chores and gift money, I focused in on the details of two particular Legos. Unless you have been living on a different planet, you know that Legos fit together with “male” and “female” pieces. This … Continue reading “Aircraft Plugs and Receptacle Connectors Are Just Like Legos – Here’s Why”

Is Insulation Resistance Testing Important?

Posted by Clare McGarrey on February 26, 2019

  Do you know what that color coating on the outside of a wire is called? It is called insulation. And did you know that the day that wire is developed, the insulation of the wire starts to age and deteriorate? Unfortunately, it is true. Wire insulation is not like a fine wine; it does … Continue reading “Is Insulation Resistance Testing Important?”

4 Critical Items to Include When Designing Aircraft Modification Kits

Posted by Clare McGarrey on January 29, 2019

  Now that US Aerospace and Defense manufacturers are extending the life of more and more older aircraft, fixed-wing and helicopter modification kits are becoming more and more prevalent. In the last 26 years InterConnect Wiring has assembled thousands of aircraft modification kits (AKA mod kits, loose wiring assemblies, or LWA’s) for a wide variety … Continue reading “4 Critical Items to Include When Designing Aircraft Modification Kits”

What is an Equipment Location Diagram and How is it Used During Wiring Harness Design?

Posted by Eric Evans on June 11, 2018

In the Aerospace Industry an equipment location diagram details the physical location of equipment installed in an aircraft.  These diagrams typically show the location of equipment with respect to an aircraft (station) coordinate system. Did you know that this XYZ system was originally developed for boats and is comprised of a fuselage station (X-axis), water … Continue reading “What is an Equipment Location Diagram and How is it Used During Wiring Harness Design?”

What is a Wiring Harness Manufacturing Specification?

Posted by John Ashour on May 29, 2018

For each new aircraft platform (a platform is an aircraft designation such as an F-15, F-16, F-18, F-35, KC-46, P-8, 787, A350, A380, etc.) that is designed and produced by the Original Equipment Manufacturer (OEM). The OEM, such as Lockheed Martin, Boeing, or Airbus, writes many manufacturing specifications for their aircraft. A few example specifications … Continue reading “What is a Wiring Harness Manufacturing Specification?”

How Should Signal Types Be Separated When Designing Aircraft Disconnects?

Posted by Marc Piloian on April 9, 2018

Modern combat aircraft like the F-16, F-18, F-22, F-35 (and some newer F-15’s) are all fly-by-wire aircraft. This means loss or degradation of the electrical system could result in the pilot being unable to control the aircraft even if the propulsion system is still operable. This makes it very important that the Electrical Wiring Interconnect … Continue reading “How Should Signal Types Be Separated When Designing Aircraft Disconnects?”

What are Disconnects and Why Do Aircraft Have Them?

Posted by Chris Vardy on March 19, 2018

A question I get asked often is “How many electrical wiring harnesses are in a single F-16?”  The exact number is dependent on when the F-16 was assembled and what country is flying the F-16.  So, what does that have to do with disconnects? It has to do with aircraft maintenance and safety.  The more … Continue reading “What are Disconnects and Why Do Aircraft Have Them?”
