Landing aids are tools and systems that help pilots safely land aircraft, especially in challenging weather conditions. These aids include visual signals, such as runway lights, and electronic systems like Instrument Landing Systems (ILS) that provide guidance to pilots during the approach and landing phases. Another common type of landing aid is the Precision Approach Procedure, which uses radar and other technologies to assist pilots in aligning with the runway. These aids enhance safety by improving visibility and accuracy, ensuring that aircraft can land smoothly and efficiently, even in low-visibility situations.
