A Precision Approach Procedure is a type of aircraft landing approach that allows pilots to land with high accuracy, especially in low visibility conditions. This procedure uses advanced navigation systems, such as the Instrument Landing System (ILS), which provides precise lateral and vertical guidance to the runway. During a precision approach, pilots rely on instruments to follow a defined path, ensuring a safe descent and landing. This method is crucial for airports with challenging weather conditions, as it enhances safety and efficiency in air traffic operations. The use of precision approaches is regulated by aviation authorities like the Federal Aviation Administration (FAA).
