In what type of weather should a pilot avoid flight?

The selection of severe thunderstorms and heavy precipitation as the type of weather a pilot should avoid is based on the significant hazards these conditions present. Severe thunderstorms are associated with turbulence, strong winds, hail, and lightning, all of which can severely impact the safety and control of an aircraft. Heavy precipitation can lead to reduced visibility, low ceilings, and increased risk of icing, which complicate flight operations and decision-making.

In contrast, clear skies and light winds generally provide optimal flying conditions, and while cold temperatures and high altitudes require specific considerations, they do not inherently pose the same immediate risks as severe storms. Foggy and low visibility conditions can indeed be hazardous; however, they typically do not have the same range of dangers associated with severe thunderstorms. In flight training and operations, the avoidance of severe thunderstorms is a fundamental tenet due to the potential for catastrophic incidents.
