A SIGMET issued for thunderstorm-related hazards, including severe thunderstorms, tornadoes, heavy precipitation, hail, and strong winds. Convective SIGMETs are reviewed during preflight hazard checks because they identify areas where VFR and IFR flight may be unsafe.

- CrosswindA wind component that blows perpendicular to the aircraft's direction of travel, particularly relevant during takeoff and landing. Pilots use specific techniques (crab method or wing-low method) to compensate for crosswind conditions.
- CTAF (Common Traffic Advisory Frequency)The frequency used by pilots to announce position and intentions at nontowered airports. CTAF communications help aircraft maintain traffic awareness in the pattern and on the ground when no control tower is operating.
- Dead ReckoningA navigation method where the pilot calculates their current position by using a previously determined position, then advancing that position based on known speed, elapsed time, and course. It's a fundamental piloting skill used alongside electronic navigation.
