11   Experienced pilots often have more trouble than novice

respect the wind as much as they should.

The passage implies that the heavier aircraft mentioned

above are

      harder to land than ultralight aircraft 

      not as popular with pilots as ultralight aircraft 

      not as safe as ultralight aircraft 

      more fuel-efficient than ultralight aircraft 

      easier to handle in wind than ultralight aircraft
