Aviation Weather Handbook (2025): FAA-H-8083-28A

Aviation Weather Handbook (2025): FAA-H-8083-28A is the FAA’s latest and most comprehensive weather reference for pilots and aviation professionals. Released in December 2024, this full-color edition officially supersedes the 2022 Aviation Weather Handbook (FAA-H-8083-28) and reflects current standards and practices used in the National Aerospace System (NAS).

This handbook consolidates weather guidance previously spread across six FAA Advisory Circulars into a single, authoritative resource. The following ACs were canceled and replaced by this publication:

• AC 00-06 – Aviation Weather

• AC 00-24 – Thunderstorms

• AC 00-30 – Clear Air Turbulence Avoidance

• AC 00-45 – Aviation Weather Services

• AC 00-54 – Pilot Windshear Guide

• AC 00-57 – Hazardous Mountain Winds

Designed as a technical reference, the Aviation Weather Handbook supports pilots, dispatchers, and operators in effective flight planning and operational decision-making. It provides a complete overview of the U.S. aviation weather program, including weather theory, aviation weather hazards, and the interpretation and use of aviation weather products and services.

Suitable for both student and experienced pilots, this handbook serves as an essential guide to understanding weather phenomena and their direct impact on flight safety and efficiency.
