  1. 500 feet AGL
  2. 400 feet MSL
  3. 400 feet AGL ✔

Why: Part 107 limits small drones to 400 feet above ground level. AGL is measured from the ground below the drone, not from sea level.

Huh, didn't know that: The altitude limit is in section 107.51, which the FAA can waive with a certificate of waiver.
