Weather Information
Lesson Plan


  • Research a mishap case study:
  • Discuss how the initial conditions developed into an incident/accident/mishap
  • Relate similar personal experience of the same type of incident/accident/mishap


  • Regardless of your experience level, weather is likely to be a key factor in your decision-making process
  • A pilot's ability to find and interpret weather is essential to make well-informed decisions
    • Failure to recognize deteriorating weather conditions leads to a exceptionally high mishap and associated lethality rate
  • Weather service to aviation is a joint effort between federal agencies, the military weather services, and other aviation-oriented groups and individuals
  • The National Weather Service operates a network of radar sites for detecting coverage, intensity, and movement of precipitation
    • FAA and DOD radar sites in the western sections of the country supplement the network
    • Local warning radar sites augment the network by operating on an as-needed basis to support warning and forecast programs
  • Think you've got a solid understanding of weather and atmosphere? Don't miss the weather and atmosphere quiz below and the topic summary
