Weather Hazards - Hail
All weather hazards could mean a greatest risk to aviation operations, however, in my post I have chosen to speak about hail. Hail is part of the category of Thunderstorms, which are categorized as hazardous by the DOT (2013), as they can result in an aircraft accident and deaths for passengers and crew on board. Hail falls under the “single cell” category, as on hot and humid summer days, a single cell (or common) thunderstorm cell will frequently form. These cells have the potential to be severe, producing hail and microburst winds.The most dangerous thunderstorm threat to airplanes is hail, which competes with turbulence. Drops that have been supercooled above the freezing point begin to solidify. When a drop freezes, subsequent droplets latch on, causing the hailstone to expand (sometimes even into a massive iceball). Severe thunderstorms with powerful air currents that have risen to enormous heights generate massive hail. These will inevitably fall, and may be seen in the skies ...
