Which document provides information regarding designated airspaces?

The designated airspaces are specifically outlined in the Designated Airspace Handbook. This document serves as a comprehensive resource that details all controlled airspace regions, including their dimensions, types, and any associated restrictions or requirements for operating within them. It is crucial for pilots to reference this handbook to ensure they are aware of the specific airspace they are entering, which has implications for flight planning, safety, and compliance with regulations.

While other documents may contain useful information related to airspace, such as regulations or procedures, they do not focus specifically on designated airspaces in the way the Designated Airspace Handbook does. For example, an Aeronautical Information Circular provides updates and general information on aviation matters, but it does not concentrate on airspace classifications and details. Departure and Approach Procedures primarily guide pilots in specific airport operations, while a Flight Operations Manual outlines the operational standards of an airline or operator, covering a wide range of topics without centering specifically on airspace designations.
