IASD Drone Operations Practice Test

In a UAS traffic advisory, location is described using a distance and a direction from a familiar reference point, like the airport. This makes it quick and unambiguous for other pilots to pinpoint where the UAS is. The phrase that best fits is “operating five NM south of the airport” because it conveys both the exact distance (five nautical miles) and the correct direction (south) relative to the airport, using standard aviation units. The other options give an incorrect location: one uses the opposite direction, another uses a different distance, and the last uses a different direction still. So this phrasing most clearly communicates where the UAS is to other airspace users.
