What is the purpose of issuing a SIGMET?

Answer: C — To warn pilots of dangerous weather conditions

The purpose of issuing a SIGMET, which stands for Significant Meteorological Information, is specifically to warn pilots of dangerous weather conditions that could affect the safety of flight operations. These advisories are crucial because they alert pilots to significant and potentially hazardous phenomena such as severe turbulence, thunderstorms, icing, and volcanic ash that may impact their route. The focus on informing pilots about severe weather situations helps them make informed decisions regarding their flight paths and ensures that safety is prioritized. This is especially important in preventing accidents and incidents that can occur due to unforeseen weather changes. The information shared through SIGMETs is based on real-time meteorological data and is vital for maintaining flight safety and efficiency.
