When inspecting a tower with a height of 1,000 feet AGL, what is the maximum altitude at which you can operate an sUAS according to 14 CFR Part 107?

In accordance with 14 CFR Part 107, when you are operating a small unmanned aircraft system (sUAS) near a structure, you are allowed to fly up to 400 feet above the height of that structure. Since the tower in this scenario is 1,000 feet above ground level (AGL), the maximum altitude at which you can legally operate your sUAS would be 1,000 feet plus 400 feet, resulting in a maximum altitude of 1,400 feet AGL.

This regulation allows for the inspection of tall structures while ensuring safety and compliance with air traffic regulations. It helps maintain a safe distance from other aircraft and ensures that the sUAS can operate without interfering with manned aviation. Thus, flying as high as 1,400 feet AGL provides the necessary altitude to inspect the tower efficiently while adhering to the legal requirements.
