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.
Rebar alone would flex too much and cement alone would crack easily. However, when combined to form a composite, an extremely rigid material is created. The composite material most commonly associated with the term composite is Fiber Reinforced Plastics. This type of composite is used extensively throughout our daily lives. Common everyday uses of fiber reinforced plastic composites include: Aircraft. Boats and marine. Sporting equipment. (Golf shafts, tennis rackets, surfboards, hockey sticks, etc.) Automotive components. Wind turbine blades.
