9.2 Weather Hazards
Weather Hazards: Icing Flight Safety is the most important necessity when it comes to aircraft design and operations. Flight safety though can be affected by several unfavorable meteorological conditions. There are several weather hazards that may impact aviation operations, however, the one which I feel poses the biggest threat to operations is icing. Icing occurs when precipitation aggregates on any part of the external structure of an aircraft. Ice may affect the function of the wings, propellers, control surface, and even pilot tubes, air intakes, and radio antennas. Aircraft encountering icing may experience an increase of aerodynamic weight and drag and a reduction in lift and thrust which may result in extremely dangerous flying. There are three types of icing, these include; rime, clear, and mixed. The most common type of icing is rime. This occurs when raindrops quickly freeze upon striking the aircraft. Rime ice usually stays on the leading edges of an aircraft. Clear ice,
