Youtube Hang Glider Pilot Cloud Flying

[Bill Berson]

The ultralight or certificated glider pilot is legal if 1200agl (above the mountain) and clear of clouds. So it's a good idea for the faster airplane pilots to avoid these glider zones. Because even though the ultralight is legally suppose to give way, it can't easily if a fast airplane comes from behind.
The sailplane pilot has the legal right of way over the airplane pilot. So best for the airplane pilot to avoid these glider areas.
