Approach plates are essential documents used by pilots during the landing phase of flight. They provide detailed information about the approach path to an airport, including altitudes, navigation aids, and runway information. These plates help ensure safe and efficient landings, especially in low visibility conditions. Each approach plate is designed for a specific runway and includes various procedures, such as Standard Terminal Arrival Routes (STARs) and Instrument Landing System (ILS) approaches. Pilots must be familiar with these plates to navigate safely and comply with air traffic control instructions during the approach and landing phases.
