What is an approach plate used for in aviation?

An approach plate is a vital resource in aviation that provides detailed navigational information specifically for landing at an airport. It includes crucial data such as the runway layout, obstacle information, and the specific approach procedures to be followed during the descent and landing phases. This information allows pilots to accurately and safely navigate the aircraft to the runway, ensuring compliance with standard operating procedures and regulations.

Approach plates contain various elements such as minimum altitudes, approach fixes, and recommended flight paths that aid in the safe execution of instrument approaches, particularly in low visibility conditions. This enables pilots to make informed decisions about their approach and landing sequences, enhancing safety and operational efficiency.

Other options, while related to aviation operations, focus on different aspects. For instance, airspeed limitations during takeoff are typically found in the aircraft's operating manual or pilot's operating handbook rather than on an approach plate. Weather conditions over a flight route are provided through weather briefings or weather services rather than being depicted in approach plates. Communication frequencies for airports are listed in charts designed for operational communication but are not the primary focus of approach plates. Thus, the distinctive role of approach plates in ensuring a safe transition from the air to the ground underscores their importance in aviation.
