Bridging the Lingo Gap for the Aerospace & Defense Newbie

As professionals in the aerospace and defense industry employed as the program managers or business development/sales of your company, your position requires you to interact with other defense company personnel and attend industry conferences. If you have been in the industry for some time, understanding what is being discussed and communicating your own thoughts is a little easier when you understand the vocabulary.

On the other hand, if you are brand new to the community and you are sitting in a meeting without a common vernacular with those across the table, it is quite a disadvantage. In the Aerospace and Defense business, one of the biggest hurdles to entry is understanding what everyone around you is saying. You may comprehend the basic language, but you hear acronyms like?ITAR, CIF, DLM,?USML, and MTFB sprinkled along the conversation and you may feel lost. Conducting everyday business in the aerospace and defense industry can be very confusing when you don’t know the lingo.

Industries all typically have their own language they share to communicate quickly and efficiently. However, there may not be an industry quite like the AeroDef community that connects military, engineering, science, astronautics, and aeronautics entities, who all have their own acronyms and terms. Combined these with globally connected militaries, governments, and corporations around the world, all with their own languages, and it is even more difficult.

Grow Your Vocab

To help you get a firmer footing in this fast-paced, quick-growing, and exciting industry, we tasked our own Duotech professionals with contributing the acronyms and terms they commonly use in everyday business. We compiled them below in alphabetical order. The acronyms are identified for what they represent, but a more detailed description is not included. Looking them up further will hopefully assist in your retention of the information.

NASA Technology Readiness Levels

Technology Readiness Level (TRL)

As a bonus, we share the Technology Readiness Level or TRL. The scale assists in uniform communication of a program’s development status. Based on the TRL, a Director of Technical Sales can easily convey to an International Program Manager what the technical maturity is of a system or product.

Various agencies like the U.S. Department of Defense, U.S. Department of Energy, National Aeronautics and Space Administration (NASA), European Space Agency (ESA), European Commission (EC), and the Oil and Gas Industry each have their own unique definitions on the scale. Primarily, they all begin at 1 being “Basic principles observed and reported” and up to 9 as a “Proven system…”

It would be difficult to include every term and acronym that is commonly used in the aerospace and defense industry. We understand there are many more expressed at any AeroDef events like the F-16 TCG Worldwide Review or the Farnborough and Singapore Air Shows.?Infographic: Learning Trade Regulations

So, what are the ones we left out? Go to our comments section below, tell us the events you take part in, and share the acronyms and terms you often use when communicating with other Aerospace and Defense professionals.
