Study Notes
AIRMETs
- AIRMET stands for Airmen's Meteorological Information, issued by the National Weather Service.
- AIRMETs inform pilots of less severe weather conditions significant for aircraft operations.
- Issued every six hours or as needed, AIRMETs cover less severe weather impacting smaller aircraft or those with lower performance capabilities.
- Three types of AIRMETs:
- AIRMET Sierra: Addresses IFR conditions and major mountain obscuration.
- AIRMET Tango: Covers moderate turbulence, sustained surface winds of 30 knots or greater, and non-convective low-level wind shear.
- AIRMET Zulu: Highlights moderate icing conditions and outlines freezing level heights.
- AIRMET information includes type, location, altitude range, and expected conditions.
- Crucial for pre-flight planning and in-flight decision-making, impacting visibility, winds, and overall flight safety.
SIGMETs
- SIGMET stands for Significant Meteorological Information, alerting pilots to severe weather threats applicable to all aircraft types.
- SIGMETs cover a broader range of severe weather phenomena compared to AIRMETs.
- Common conditions addressed by SIGMETs include:
- Non-convective severe turbulence.
- Severe or extreme icing.
- Dust storms and volcanic ash affecting visibility and aircraft safety.
- SIGMETs are unscheduled and valid for four hours, possibly reissued if conditions persist longer.
- Essential for pre-flight planning and in-flight adjustments, ensuring pilots can respond to rapidly changing severe weather.
Convective SIGMETs
- Convective SIGMETs are a specific type of SIGMET focused on convective weather phenomena.
- Indicate severe turbulence, severe icing, and low-level wind shear associated with thunderstorms.
- Important for all aircraft, highlighting the potential hazards posed by severe thunderstorms.
Importance of Weather Advisories
- Understanding AIRMETs, SIGMETs, and Convective SIGMETs is critical for flight safety.
- Effective monitoring and analysis of these advisories enhance risk management during flights.
- Ignoring these advisories can have serious legal and safety implications for flight operations.
- Adapting flight plans based on weather advisories ensures the safety and efficiency of aviation operations.
Practical Integration
- Review all relevant AIRMETs and SIGMETs during pre-flight planning.
- Continuously monitor updates while in-flight to make informed decisions regarding routes and altitudes.
- Awareness of weather advisories supports pilots in making timely adjustments to ensure passenger comfort and safety.
Upcoming Learning
- Further discussion will focus on Aircraft Performance and Weather, emphasizing how weather advisories affect flight safety and aircraft performance.

AIRMETs Overview
- AIRMET: Airmen's Meteorological Information, a non-severe weather advisory for pilots.
- Issued by the National Weather Service for conditions not intense enough to qualify as SIGMETs.
- Typically refreshed every six hours or as needed, targeting mostly light aircraft.
Types of AIRMETs
- AIRMET Sierra: Covers IFR conditions and mountain obscuration.
- AIRMET Tango: Alerts to moderate turbulence, winds of 30 knots or more, and low-level wind shear.
- AIRMET Zulu: Focuses on moderate icing and indicates freezing level heights.
Importance of AIRMETs
- Alerts pilots to weather changes affecting visibility and safety.
- Essential for thorough pre-flight planning and in-flight decision-making.
- Ignoring AIRMETs can lead to legal and safety repercussions for flight operations.
Integrating AIRMETs into Flight Planning
- Review relevant AIRMETs during pre-flight and monitor updates in-flight.
- Be prepared to adjust course or altitude based on AIRMET advisories for safety.
SIGMET Overview
- SIGMET: Significant Meteorological Information, alerts pilots about severe weather threats affecting all aircraft.
- Covers non-convective severe phenomenon like severe icing, turbulence, dust storms, and volcanic ash.
Differences Between AIRMETs and SIGMETs
- AIRMETs: Moderate weather concerns primarily for smaller aircraft and visual flight operations.
- SIGMETs: Severe weather warnings valid for all aircraft types, indicating serious conditions under instrument flight rules.
Convective SIGMETs
- A subset of SIGMETs addressing hazards associated with thunderstorms.
- Includes severe turbulence, severe icing, low-level wind shear, and warnings about embedded thunderstorm activity.
Practical Application
- Pilots must analyze advisories to assess weather implications for their aircraft.
- Decisions might include route alterations, flight delays, or cancellations to enhance safety.
Summary
- AIRMETs inform about potentially challenging conditions, while SIGMETs and Convective SIGMETs warn of severe dangers.
- Accurate interpretation of these advisories allows pilots to make informed, safety-oriented decisions in flight operations.
