Icing conditions exist when the air contains droplets of supercooled water. They freeze on contact with a potential nucleation site, which in this case is the parts of the aircraft, causing icing. Icing conditions are characterized quantitatively by the average droplet size, the liquid water content and the air temperature.
The aircraft developed severe icing on its wings and crashed. The captain was the sole survivor, though he would die a year later in another aviation accident. February 26, 1941 8 8 8 Eastern Air Lines Flight 21: Morrow: Georgia: Douglas DC-3: The aircraft struck terrain during approach due to improperly set altimeters. August 31, 1940 25 0 0
Aircraft icing increases weight and drag, decreases lift, and can decrease thrust. Ice reduces engine power by blocking air intakes. When ice builds up by freezing upon impact or freezing as runoff, it changes the aerodynamics of the surface by modifying the shape and the smoothness of the surface which increases drag, and decreases wing lift ...
The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration". The legend of an aeronautical chart lists many of the symbols, colors and codes used to convey information to the map reader.
The structural icing of an aircraft is largely determined by three factors: supercooled liquid water content, which decides how much water is available for icing; air temperature, with half of all reported icing occurring between −8 °C (18 °F) and −12 °C (10 °F); and droplet size, with small droplets influencing aircraft's leading edges ...
Jeppesen (also known as Jeppesen Sanderson) is an American company offering navigational information, operations planning tools, flight planning products and software.. Jeppesen's aeronautical navigation charts are often called "Jepp charts" or simply "Jepps" by pilots, due to the charts' popul
