  1. All other aircraft ✔
  2. Only aircraft larger than the ultralight
  3. Only aircraft on instrument flight plans

Why: Ultralight pilots must keep watch so they can see and avoid aircraft, and they must yield the right-of-way to all aircraft.

Huh, didn't know that: Part 103 also says no one may fly an ultralight in a way that creates a collision hazard with any aircraft.

The dad joke
Why was the ultralight so polite? It always said 'after you' to every aircraft.
