A remote pilot is flying at 200 feet AGL when the aircraft enters a thin layer of low cloud. The pilot can no longer see the drone. What is required by regulation?

Why →14 CFR § 107.31 requires the remote PIC to maintain visual line of sight at all times during flight. Entering a cloud breaks VLOS. The regulation contains no grace period. The pilot must take immediate action to reestablish visual contact, which in this case means descending the aircraft below the cloud layer. Operating by reference to a ground station display alone does not satisfy the VLOS requirement.

The trap →Landing by instrument-only ground station guidance describes instrument flight, which is not an authorized method of satisfying VLOS under Part 107. The continue-for-30-seconds option invents a 30-second grace period that does not exist in the regulations.

Field note →§ 107.51(d) requires a drone to remain at least 500 feet below clouds and 2,000 feet horizontally from clouds. A thin cloud layer at 200 feet AGL is a weather condition the pre-flight assessment should have caught.
