What does Part 107 say about operating a small unmanned aircraft from a moving aircraft?

Part 107 addresses operation from a moving vehicle with a narrow allowance and an explicit exclusion. Operating from a moving land or water-borne vehicle is permitted only over a sparsely populated area, and not at all where the operation is for compensation or hire — that is the moving-vehicle provision people remember. What it never covers is operation from a moving aircraft, which is prohibited outright with no sparsely populated exception and no waiver pathway of the ordinary kind. The reason is straightforward: a control station aboard an aircraft in flight means the operator is subject to the aircraft's own motion, has an unstable and constantly changing viewpoint, and cannot reliably maintain visual line of sight with a small unmanned aircraft while the platform moves. The prohibition is one of the clean absolutes in the rule, which is why questions test it against the more permissive land-vehicle case.

Part 107 prohibits operating a small unmanned aircraft from a moving aircraft. The limited moving-vehicle allowance covers land and water-borne vehicles only.

Part 107 permits operation from a moving land or water-borne vehicle only over sparsely populated areas and not for compensation or hire, and prohibits operation from a moving aircraft entirely.

Ground and Water Maybe, Air Never. And the ground allowance dies the moment you are being paid.

The compensation restriction on the land-vehicle case catches commercial operators specifically. Even over sparsely populated ground, paid work from a moving vehicle is out.
