While I would not expect ROS to be FAA certifiable on its own, I am wondering if any users have ROS implementations that have gone through the FAA certification process. If so, I would like to get some insight into lessons learned, things to watch out for, etc. Basically I am trying to get a sense of the potential certifiability of a ROS implementation on large unmanned aerial vehicles.
Based on my own experience with certification (not of a ROS system), i think it would be very cost-prohibitive to certify a ROS 1-based system.
You might have an easier time with a ROS 2-based system. The software development process has been better tracked.
