— WHY MILESYS
Four reasons to choose us
01
Industrial sovereignty
Design, three engineering offices, and production in Élancourt (78). No offshore subcontracting on the critical path. We prioritize sourcing from France and Europe and document the supply chains for each project.
02
45 Years in Business · ISO 9001:2015
Your critical equipment depreciates over 10 to 25 years. We've been around for 45. We offer components maintained for the program's duration, continuous engineering support, proactive anti-obsolescence plans, and an ISO 9001:2015 certified quality system.
03
PRM Compliance · EC 1107/2006
The French Accessibility Act of 2005, European Directive EC 1107/2006, and CEAC Doc 30 are systematically applied to all airport equipment. The majority of French airports use Milesys; over 10 European airports have followed suit.
04
Custom Capacity · 3 Engineering teams
Three engineering teams on a single site: electronics, real-time software, and mechanical. Legacy to IP gateways, obsolescence management, and specific design for equipment not found in the catalog.
— ÉLANCOURT (78)
Engineering teams and production line, on a single site
Our Élancourt site brings together design (electronics, software, and mechanical engineering), test bench facilities, in-house developed industrial tooling, and manufacturing. Each piece of equipment is developed, prototyped, qualified, and produced there. It's also where we welcome our clients and integrators for technical reviews and quality audits.

Nos capacités
— OUR VALUES
An industrial partner, not a supplier
Expertise
Our engineers handle projects from start to finish. Three integrated design offices, internally developed testing tools.
Agility
We adapt the scope to the real need, not the other way around. Open frameworks are costed before any study is undertaken.
Trust
Long cycles demand that we keep our word for 10 to 25 years. Our clients still call us 30 years later.
Transparency
Both good news and bad. Decisions are made together, not behind your back.
Let's talk about your project
Ongoing project, upcoming RFQ, or just a technical question. We will get back to you within 48 hours for an initial technical discussion.
