If the primary UAS is not airworthy, what action should be taken?

• A. Proceed with flight using the backup
• B. Continue with the same UAS but with caution
• C. Select another UAS
• D. Abort the mission and wait

Answer: (C)

The important idea is that you must fly only airworthy equipment. If the primary UAS is not airworthy, you should switch to a different UAS that is airworthy and ready to fly. This keeps the mission on a system that has been checked, is within maintenance and performance limits, and meets safety and regulatory expectations. Selecting another UAS ensures you’re using a platform you can trust to perform as intended without introducing known faults. If there isn’t another airworthy UAS available, aborting the mission and waiting until one is available is the safer option. Continuing with the backup or with cautions while the main unit is unairworthy would still involve flying an aircraft that isn’t verified as safe, which isn’t acceptable.
