In FAR part 103 when they are talking about visibility requirements for flying an ultralight, sometimes instead of giving exact distances, they will just say "clear of clouds".
Minimum flight visibility Flight altitudes /1/ Minimum distance from clouds 1,200 feet or less above the surface regardless of MSL altitude: (1) Within controlled airspace 3 500 feet below, 1,000 feet above, 2,000 feet horizontal. (2) Outside controlled airspace 1 Clear of clouds.
Flight Airspace visibility Distance from clouds Class G: 1,200 feet or less above the surface (regardless of MSL altitude) 1 statute mile Clear of clouds. More than 1,200 feet above the surface but less than 10,000 feet MSL 1 statute mile 500 feet below. 1,000 feet above. 2,000 feet horizontal.
What does "Clear of Clouds" mean in this context? Just that I should remain clear of the clouds, or does it mean that the sky must be clear of clouds in the defined space?
And if it does just mean I need to stay "clear of the clouds", how exactly is that defined? 1000ft? 100ft? 10ft? What exactly?
