Sound weather decisions are critical to the successful outcome of all flights, and this book details each aspect of weather as it relates to aircraft operation and flight safety. Earth’s atmosphere, common IFR procedures, high-altitude weather, and special area weather considerations are thoroughly discussed in this FAA handbook for students and instructors as well as experienced pilots. The comprehensive resource provides the knowledge needed in order to fly safely in both visual (VMC) and instrument (IMC) meteorological conditions, covering subjects such as temperatures, atmospheric pressure and altimetry, wind, moisture, precipitation, clouds, air masses and fronts, turbulence, icing, thunderstorms, arctic and tropical weather, and soaring weather. Also included are a glossary and an index.
