This document covers a broad range of topics, including the acquisition and interpretation of weather reports, forecasts, aviation charts, and much more. By following the guidelines set forth in AC 00-45H Change And, pilots can effectively assess the risk associated with weather conditions and plan accordingly.

The Importance of Weather Information in Aviation

Weather plays a critical role in aviation safety. It affects aircraft performance, visibility, and the overall comfort of passengers. Staying updated with accurate weather information enables pilots to anticipate and prepare for any potential challenges they may encounter during their flight.

Whether it's monitoring thunderstorm activity, assessing wind shear conditions, or determining visibility and cloud cover, pilots must have access to up-to-date weather data and interpret it correctly. This is where Aviation Weather Services come into play.

Types of Aviation Weather Services

The AC 00-45H Change And guide details various weather services available for pilots. These services can be broadly categorized as follows:

1. Pre-flight Weather Briefings

Before taking off, pilots can consult weather briefings provided by designated meteorological centers. These briefings contain essential information such as current weather reports, forecasts, and any significant weather phenomena that may affect their flight.

2. In-flight Weather Information

During flight, pilots can access real-time weather updates through onboard aircraft weather systems. These systems provide information on factors like turbulence, icing, and thunderstorm activity in the vicinity.

3. Aviation Weather Products

AC 00-45H Change And also covers various products, such as aviation weather charts, terminal aerodrome forecasts, and radar imagery. These products equip pilots with the necessary tools to interpret and analyze weather patterns specific to their route.

4. Weather Observations and Reports

Aviation weather observations and reports offer pilots accurate and timely data. This includes information on temperature, humidity, wind speed and direction, cloud cover, visibility, and precipitation. These observations help pilots make informed decisions during pre-flight planning and en-route operations.

Understanding Weather Symbols and Codes

AC 00-45H Change And provides a comprehensive breakdown of the weather symbols and codes used in aviation weather reports. This knowledge is vital since pilots need to understand these symbols and codes to accurately interpret weather information.

For example, the METAR (Meteorological Aerodrome Report) contains coded information about temperature, dew point, visibility, wind speed and direction, cloud cover, and more. Being able to read and decipher METAR reports allows pilots to assess the current weather conditions at their departure and destination airports.

Importance of Pilot Weather Reports (PIREPs)

In addition to accessing meteorological data, pilots can actively contribute to weather analysis by submitting Pilot Weather Reports, commonly known as PIREPs. PIREPs contain real-time observations made by pilots during their flight.

These reports cover a wide range of weather phenomena, such as turbulence, icing, cloud layers, and more. By sharing their observations, pilots help improve the accuracy and timeliness of weather forecasts, benefiting the entire aviation community.

Aviation Weather Services provided in AC 00-45H Change And are indispensable for pilots to make informed decisions regarding weather conditions and flight planning. By thoroughly understanding the content of this guide, pilots can enhance their situational awareness and ensure the safety of their passengers.

It is crucial for pilots to consult trusted meteorological sources, stay up-to-date with changes in weather patterns, and continuously educate themselves on new developments in aviation weather services. By doing so, pilots can confidently and efficiently navigate the skies, reducing the potential risks associated with adverse weather conditions.

This publication is the official Aviation Weather Services advisory circular AC00-45H. Issued by the Federal Aviation Administration (FAA) on Nov 14, 2016. Incorporates Change 1 dated Jan 8, 2018 and Change 2 dated March 6, 2019.
Current in 2022.

This AC explains U.S. aviation weather products and services. It provides details when necessary for interpretation and to aid usage. This publication supplements its companion manual, AC 00-6, Aviation Weather, which documents weather theory and its application to aviation. The objective of this AC is to bring the pilot and operator up-to-date on new and evolving weather information and capabilities to help plan a safe and efficient flight, while also describing the traditional weather products that remain. The document is organized using the FAA’s three distinct types of weather information: observations, analyses, and forecasts. (AC 00-45H cancels AC 00-45G, published October 2014).
