Why do pilots rely on onboard weather radar?

Pilots rely on onboard weather radar primarily to detect and avoid weather hazards. This technology provides real-time information about weather conditions ahead of the aircraft, including precipitation, storm systems, and turbulence. By interpreting radar data, pilots can identify areas of severe weather, such as thunderstorms or heavy rain, allowing them to make informed decisions about their flight path to ensure safety.

Using onboard weather radar is crucial in maintaining safe distances from potential hazards, which are not only important for passenger comfort but also for preventing dangerous situations such as turbulence or icing. While fuel efficiency, flight route changes, and communication with ground control are important aspects of flying, they are not the primary function of onboard weather radar. The core purpose of this technology is specifically focused on weather assessment and avoidance, making it an essential tool in a pilot's decision-making process.
