Cataracts are cloudy areas that develop within the eye lens. A healthy lens is clear like a camera's, and light has no problem passing through it to the retina at the back where images are processed. When you have a cataract, the light can't get through as easily and, as a result, you can't see as well. Cataracts often form slowly, and they don't cause symptoms like pain, redness, or tearing in the eye. Some stay small and don't affect your eyesight.
A composite flight plan is actually two flight plans-one VFR and one IFR. What makes it composite is that you will transition from one to the other at some specified point during your flight.
Today, the dream is a reality. Resembling something between a flying squirrel and a snow angel, the wingsuit allows skydivers and BASE jumpers to leap out into the void, spread their arms and soar through the air.In a sense, wingsuit flying is a cross between skydiving and hang gliding.But, until the moment they pull their parachute chord, wingsuit flyers can soar horizontally at high speeds and perform aerial acrobatics -- all while descending at a rate much slower than that of a typical skydiver.
