  1. 1 statute mile
  2. 3 statute miles ✔
  3. 5 statute miles

Why: Part 103's table asks for 3 statute miles of flight visibility in Class E below 10,000 feet MSL, with cloud clearance of 500 below, 1,000 above and 2,000 feet horizontal.

Huh, didn't know that: At or above 10,000 feet MSL in Class E, the visibility minimum rises to 5 statute miles.

The dad joke
Why do ultralight pilots check visibility? They like to keep a clear view of their future.
