Common Threads In Weather Accidents

摘要

In my view, there are four basic categories of aviation weather threats: low clouds and reduced visibility; turbulence and low-level wind shear; airframe ice; and thunderstorms (which may contain the three other hazards in one nasty package). When evaluating weather for a planned flight, I look at observations and forecasts with each of these specific hazards in mind: what is are the chances I'll encounter each threat and how bad will each be? How close to (or beyond) the limitations of the regulations, my capabilities and the airplane's performance would I be if I attempt the flight?
