Flight Director Mode Select Panel



Project Name:
FD Mode Select Panel


Systems & DO-178C Certification

- 17,300+ Hours
- 16+ Engineers
- 2+ Years

Project Scope

Between February 2015 and May 2017, Belcan developed and certified Flight Director Mode Select panel software for a civil and military helicopter manufacturer. The activities included systems engineering support, full ownership of DO-178C software development and certification, development of system/software test environments, and tools for production.



Belcan was responsible for airworthiness certification of flight software per DO-178C Level B, and for the clean sheet software architecture providing a modular and a configurable solution to replace legacy products.


Key Values / Benefits

Belcan worked with the DER to find the lowest cost technically feasible solution and successfully executed the plan to completion. The result improved system, test equipment, and production processes resulting in significant cost savings over the life of the program.
