CAA Drone Theory Practice Test

When operating a drone in relation to tall structures, the regulations state that you can legally fly your drone up to 400 feet (approximately 122 meters) above ground level. However, when flying near a structure, the FAA rules clarify that you can fly your drone higher than the structure's height, provided you do not exceed the maximum altitude of 400 feet above ground level. In this case, if the structure is 105 meters high (about 344 feet), the maximum altitude you can legally operate your drone above that structure would be limited to 400 feet above ground level, which would be 56 feet more than the structure's height. This results in a total of 400 feet but requires a safe distance from the top of the structure. Given the choices provided, option B, which allows up to 15 meters (approximately 49 feet) of additional altitude above the structure, aligns with the standard practice and regulation of maintaining safety while not exceeding overall height limits. Thus, it is the most accurate choice regarding how high you can legally fly relative to the height of a tall structure.
