Pilots, beware. Heavy rains can lead to flash flooding events – one of the primary causes of death associated with thunderstorms. 5% (49 votes) Total votes: 1031 Identify thunderstorm hazards to flight & how to avoid them. A trigger mechanism must cause the warm moist air to rise: Heating of the layer of air close to the surface. All thunderstorms are dangerous and can be associated with a number of hazards. The ordinary thunderstorms are typical summer storms and generally last approximately 60 minutes (3). Thunderstorm Hazards to Aviation Learning Goal 4b. As a pilot, however, thunderstorms are one of the most hazardous conditions you can encounter. Hazards. And severe turbulence is always a possibility near convective clouds. Frontal Hazards Learning Goal 3h. HAZARDS. In our first WX Wise webinar, let us get reacquaint you with thunderstorms. Cumulonimbus (Cb) (Cb) clouds, in which Thunderstorms are found, form when three conditions are met: There must be a deep layer of unstable air. ... Thunder is the audible manifestation of the electrical discharge, caused by the violent heating and expansion of the atmosphere surrounding the path of the lightning strike. CANCELLATION. Weather hazards include visibility restricting phenomena, blowing snow, icing, frost, and lack of contrast—whiteout. FAA Advisory Circular (AC) 00-6A, Aviation Weather, says, "For a thunderstorm to form, the air must have (1) sufficient water vapor, (2) an unstable lapse rate, and (3) an initial upward boost (lifting)." Water-droplet fog is the main hazard to aircraft operations in coastal areas during the summer. Locate likely areas of turbulence, icing, and thunderstorms relative to warm, cold, occluded fronts, and dry lines, and describe how these frontal hazards affect aviation Contents: A) Overview of Fronts B) Frontal Conditions at the Earth's Surface C) Frontal Weather Above Ground D) Occluded Fronts E) Dry Lines Here, you will find information on common weather hazards that can affect the safety of flight. Although most lightning victims survive, people struck by lightning often report a variety of long-term, debilitating symptoms. All thunderstorms can produce severe turbulence, low level wind shear, low ceilings and visibilities, hail and lightning. This advisory circular (AC) describes the hazards of thunderstorms to aviation and offers guidance to help prevent accidents caused by thunderstorms. For most, spring flying is just around the corner. The strongest turbulence occurs with the shear between updrafts and downdrafts, but turbulence has been encountered thousands of feet above a storm and up to 20 miles laterally from a storm. WEATHER HAZARDS.
A single thunderstorm cell can hold 500 000 tons of water in the form of liquid droplets and ice crystals. Lightning is a leading cause of injury and death from weather-related hazards. Cumulonimbus clouds and thunderstorms present a serious risk to aviation. Hazards associated with convective weather include thunderstorms with severe turbulence, intense up- and downdrafts, lightning, hail, heavy precipitation, icing, wind shear, microbursts, strong low-level winds, and tornadoes. The tops of the storms where lower than our maximum cruising altitude so it seemed like we would have no problem flying … Thinking of becoming a pilot?
