What is referred to as an 'approach plate' in aviation?

An approach plate is a crucial tool used by pilots during instrument approaches to airports. It provides a detailed document outlining the specific procedures for safely navigating to the runway while relying on instruments rather than visual cues. This includes important information such as altitude requirements, the geographical layout of the approach, approach fixes, and the required navigational aids. The plate ensures that pilots can execute the approach safely and in compliance with regulations, detailing aspects like missed approach procedures and any relevant communication frequencies.

In contrast, while a graphical representation of flight paths during landing does provide visual guidance, it does not encapsulate the comprehensive instructions and procedures found in the approach plate. A checklist for pre-flight inspections pertains to ensuring the aircraft is ready for flight, and a schedule of air traffic control frequencies is for communication purposes, neither of which directly addresses the procedural details needed for executing a specific approach.
