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.
Dr. Windecker believed that composite aircraft construction had a ready military application, because composites are nearly invisible to conventional radar systems. In 1962, he and Dow Chemical Company proposed a radar-invisible airplane to the Kennedy Administration, who showed no apparent interest.he certification Eagle prototype, incorporating retractable landing gear, crashed during spin testing for certification by the Federal Aviation Administration. After a redesign of the empennage, the Eagle AC-7 became the first composite airplane to receive FAA certification, in December 1969.
