-
Attention Getter:
- Research and present a mishap case study:
- Discuss how the initial conditions developed into an incident/accident/mishap
- Relate similar personal experiences of the same type of incident/accident/mishap
- Consider incorporating a case study as a guided scenario
-
Motivator:
- 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

Conclusion
-
Re-Motivation:
- Weather Information turns weather information into operational decisions that protect aircraft performance, route flexibility, and safe landing options.
- Comparing forecasts, observations, trends, aircraft limitations, and personal minimums helps pilots identify deteriorating conditions before they eliminate safer alternatives.
- Continuous weather monitoring and a willingness to delay, divert, or discontinue a flight are essential expressions of sound aeronautical decision-making.
- Further exploration of Weather Information prepares instrument pilots to interpret more complex weather systems and make increasingly confident risk-based decisions.
