Instrument Rating Aeroplane (INRAT) Practice Exam 2026 – Complete Prep Guide

A pilot can obtain a SIGMET from a Flight Service Specialist (FSS) because FSS provides important pre-flight and en-route weather information to pilots, including significant weather advisories like SIGMETs. SIGMETs are issued to alert pilots to hazardous weather that can affect the safety of flight, such as severe turbulence, thunderstorms, or volcanic ash.

The role of the FSS includes disseminating weather information, and they have access to a variety of sources to provide accurate and timely updates. Thus, pilots often rely on FSS for vital weather information, including SIGMETs, before and during their flights to enhance situational awareness and ensure safe operations.
