Under which conditions is controlling a sUAS from another vehicle allowed?

• A. Over a sparsely populated area, when no cargo is being transported for compensation
• B. In any area as long as the remote pilot is within visual line of sight
• C. Only during emergency operations
• D. Not allowed under any circumstances

Answer: (A)

Controlling a sUAS from another vehicle is tightly limited because it mixes a moving platform with the unmanned aircraft, increasing risk to people and property. The allowed scenario is a narrow exception: you may do this in a sparsely populated area and only if you’re not transporting cargo for compensation. The sparse-population condition reduces potential casualties and damage, and the non-commercial nature of the operation further lowers risk and regulatory burden. Outside those conditions—such as in populated areas or when carrying goods for pay—this practice isn’t permitted.
