Aviation Weather Service FAQ

Answers to your most common questions about Aviation Weather Service.

Quick, simple, and helpful information at a glance.

What is aviation weather?
Aviation weather refers to the meteorological conditions that are important for safe flight of aircraft.
What types of weather conditions can affect aviation?
Various types of weather conditions such as thunderstorms, icing, turbulence, and low visibility can affect aviation.
How can I access aviation weather information?
There are several ways to access aviation weather information, including through websites, mobile apps, and by contacting a flight service station.
What is a TAF?
A Terminal Aerodrome Forecast (TAF) is a weather report specifically for a particular airport, including expected precipitation, wind speed and direction, and temperature.
Where can I find TAFs?
TAFs can be found on numerous websites and mobile apps, as well as through flight service stations and air traffic control.
What is a METAR?
A METAR is a routine weather report that provides current meteorological information for a specific airport, including wind speed and direction, visibility, and clouds.
How often are METAR reports issued?
METAR reports are typically issued every 30 minutes, but can be updated more frequently if conditions change significantly.
Where can I find METAR reports?
METAR reports can be found on various websites, mobile apps, and through flight service stations.
What is a NOTAM?
A Notice to Airmen (NOTAM) is a notice issued to pilots regarding important information or changes to aviation facilities, procedures, or hazards.
How often are NOTAMs issued?
NOTAMs are issued as needed, typically 24 hours in advance for planned changes and immediately for unexpected changes.
Where can I find NOTAMs?
NOTAMs can be found on various websites, mobile apps, and through the Federal Aviation Administration (FAA) NOTAM System (https://notams.aim.faa.gov/).
What is air turbulence and how does it impact aviation?
Air turbulence is a sudden, irregular movement of air that can occur at any altitude and is caused by changes in air pressure or wind. It can affect flight safety and comfort.
How can I check for turbulence before a flight?
You can check the turbulence forecast on various websites, such as the Aviation Weather Center (https://aviationweather.gov/turbulence/), or by contacting a flight service station.
What is icing and how does it impact aviation?
Icing is when a buildup of ice forms on an aircraft's surface, including the wings, which can decrease performance and potentially cause control issues.
How can I check for icing conditions before a flight?
You can check for icing conditions on various websites, such as the Aviation Weather Center (https://aviationweather.gov/icing/), or by contacting a flight service station.
What is a SIGMET?
A SIGMET is a Significant Meteorological Information report that warns pilots of hazardous weather conditions, such as severe turbulence, icing, and thunderstorms, that can affect a large area.
How often are SIGMETs issued?
SIGMETs are issued as needed, typically every 4-6 hours or more frequently for rapidly changing conditions.
Where can I find SIGMETs?
SIGMETs can be found on various websites, mobile apps, and through the Federal Aviation Administration (FAA) Aviation Weather Center (https://aviationweather.gov/sigmet/).
What is a Convective SIGMET?
A Convective SIGMET is a Special Meteorological Information report that warns pilots of severe weather associated with thunderstorms, such as heavy precipitation, hail, and tornadoes.
How often are Convective SIGMETs issued?
Convective SIGMETs are issued as needed, typically every 2 hours or more frequently for rapidly changing conditions.
Where can I find Convective SIGMETs?
Convective SIGMETs can be found on various websites, mobile apps, and through the Federal Aviation Administration (FAA) Aviation Weather Center (https://aviationweather.gov/convectivesigmet/).
What is low-level wind shear and how does it impact aviation?
Low-level wind shear is a sudden change in wind speed and/or direction at a low altitude, which can create dangerous flight conditions and disrupt takeoff and landing.
How can I check for low-level wind shear before a flight?
You can check the Low-Level Wind Shear forecast on various websites, such as the Aviation Weather Center (https://aviationweather.gov/lowshear/), or by contacting a flight service station.
What is a microburst and how does it impact aviation?
A microburst is a small but strong downdraft of wind that can cause sudden and intense changes in wind speed and direction, potentially affecting flight safety and performance.
How can I check for microburst conditions before a flight?
You can check the microburst forecast on various websites, such as the Aviation Weather Center (https://aviationweather.gov/microburst/), or by contacting a flight service station.
What does "VFR" and "IFR" mean?
VFR stands for Visual Flight Rules, which require pilots to maintain visual contact with the ground and other aircraft. IFR stands for Instrument Flight Rules, which allow pilots to fly relying solely on instruments due to poor visibility.
How do I know if my flight is operating under VFR or IFR?
Your pilot or airline should inform you about the type of flight they are conducting.
What are METAR remarks and why are they important?
METAR remarks are additional information that are not included in the main METAR report, but can provide important details about weather conditions, such as lightning, hail, and precipitation type.
How can I interpret METAR remarks?
METAR remarks can be interpreted with the help of glossary terms, such as the Aviation weather Glossary (https://www.aviationweather.gov/static/help/glossary.pdf), and by seeking clarification from a flight service station or air traffic control.
Where can I find a glossary of aviation weather terms?
The Aviation Weather Center provides a glossary of terms online: https://www.aviationweather.gov/static/help/glossary.pdf. They can also be found in various pilot training materials and textbooks.
What should I do if I receive an error message when trying to access aviation weather information?
You can try refreshing the page or app, clearing your browser cache, or using a different device. If the issue persists, you can contact the website or app's customer support for assistance.
Where can I find more information about aviation weather and safety?
You can find more information on aviation weather and safety through various sources, such as the Federal Aviation Administration (https://www.faa.gov/) and the National Oceanic and Atmospheric Administration (https://www.noaa.gov/). You can also consult with a flight instructor or aviation weather expert for guidance.
