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.
What Are Composites? A composite is a material made from two or more different materials that, when combined, are stronger than those individual materials by themselves. Simply put, composites are a combination of components. In our industry, composites are materials made by combining two or more natural or artificial elements (with different physical or chemical properties) that are stronger as a team than as individual players.
