Aviation Weather
Weather systems, atmospheric behavior, and hazardous phenomena that affect flight safety and planning.
Weather is one of the most significant variables in aviation safety. Understanding atmospheric behavior — how fronts move, why turbulence forms, where icing occurs — is essential for every pilot and dispatcher.
This topic covers the atmospheric phenomena and weather hazards that directly affect flight: air masses and fronts, turbulence types (including clear-air turbulence), aircraft icing conditions, wind shear, thunderstorm hazards, and the broader weather systems that drive them.
The guides here focus on understanding weather as a physical system. For interpreting coded weather reports (METARs, TAFs, RVR), see the Weather Reporting & Products topic.

Key terminology
Essential glossary terms associated with this topic.
AileronTopic: Aircraft PerformanceAilerons are movable control surfaces on aircraft wings that control roll. The pilot deflects them to bank the aircraft left or right, with each aileron moving in the opposite direction to create differential lift. Air MassTopic: Flight Controls & StabilityA large body of air with roughly uniform temperature and humidity that forms when air stagnates over a region long enough to adopt that area's surface characteristics. Air Traffic ControlTopic: Airline Operations & EconomicsAir Traffic Control (ATC) is a ground-based service that directs aircraft movement and maintains safe separation in the air and on airport surfaces through radar, radio communication, and standardized procedures. AirfoilTopic: AerodynamicsAn airfoil is any surface shaped to generate lift when air flows over it. Wings, propeller blades, and rotor blades are common airfoils used in aircraft. Airline AllianceTopic: AerodynamicsA formal agreement between two or more airlines to coordinate operations, share routes, and link frequent flyer programs, allowing passengers to earn and redeem miles across all partner carriers on a single journey. AIRMETTopic: Weather Reporting & ProductsAn aviation weather advisory issued by the National Weather Service warning pilots of moderate weather hazards such as turbulence, icing, and instrument flight conditions that may affect general aviation operations. AirspeedTopic: AerodynamicsAirspeed is the speed of an aircraft relative to the surrounding air mass. It is measured by a pitot-static system and serves as the primary reference for aircraft performance, control, and safety. Altimeter SettingTopic: Aircraft PerformanceThe barometric pressure value a pilot sets in an altimeter to correct for local atmospheric conditions and ensure accurate altitude readings above mean sea level. Anti-Ice SystemsTopic: Aviation WeatherAnti-ice systems prevent ice formation on critical aircraft surfaces by maintaining heat through bleed air, electrical elements, or glycol fluid, working proactively before ice can accumulate. ATCTopic: Aircraft PerformanceAir Traffic Control (ATC) is the ground-based service that guides and separates aircraft in the air and on the ground to maintain safety and efficiency in controlled airspace. Bleed AirTopic: Aircraft SystemsBleed air is hot, high-pressure air extracted from a jet engine's compressor and routed to aircraft systems like cabin pressurization, air conditioning, and anti-ice protection. Cabin PressurizationTopic: AerodynamicsCabin pressurization is the process of maintaining safe, breathable air pressure inside an aircraft cabin during high-altitude flight, where outside air is too thin to sustain human life.
