What is an approach plate used for?

An approach plate is primarily used to execute a specific instrument approach. It contains detailed information essential for pilots to safely navigate and land at an airport under instrument flight rules (IFR). The plate provides critical data such as altitude restrictions, route guidance, navigation aids, and other necessary procedures to follow during the approach phase of flight. This information is crucial for ensuring both safety and compliance with aviation regulations when transitioning from enroute flight to landing.

While weather updates, departure routes, and fuel requirements are relevant to flight planning, they are not the primary function of an approach plate. Instead, those topics are addressed through other resources and documents in a pilot's flight planning process.
