Can you describe your involvement with flight testing and validation processes for autonomous systems?

Testing is where theory meets reality. Inquire about their hands-on experience with flight tests. How do they plan and execute these tests? What validation techniques do they use to ensure the system performs as expected? Their methods can give you insight into their thoroughness and practical know-how.

What methods do you use to ensure the cybersecurity of autonomous flight systems?

Cybersecurity is non-negotiable. Malicious actors can wreak havoc on unsecured UAVs. Ask about their experience in securing UAV systems. Do they use encryption, secure boot mechanisms, or network security protocols? Their vigilance in this area can protect your UAVs from becoming high-tech liabilities.

Explain your experience with mapping and localization techniques in the context of UAVs.

Mapping and localization are key for autonomous navigation. Question them on techniques like GPS, LiDAR-based mapping, or photogrammetry. Have they developed or refined any of these methods? Their expertise can ensure your UAVs can find their way even in uncharted territories.

Do you have experience with hardware-in-the-loop (HIL) testing for autonomous systems?

HIL testing is like a dress rehearsal for your UAV systems. Are they familiar with setting up these tests, which combine real hardware with simulated environments? Experience here indicates they know how to validate system performance before deploying into the field.

How do you keep up with the latest advancements and trends in autonomous aviation technology?
