Instrument Approach Procedures (IAPs) are standardized methods used by pilots to safely navigate an aircraft to the runway during low visibility conditions. These procedures provide specific guidance on how to approach an airport, including altitude, speed, and navigation aids, ensuring a safe landing. IAPs are essential for maintaining safety in aviation, especially in adverse weather. They utilize various navigation systems, such as GPS and ILS (Instrument Landing System), to help pilots align with the runway. Each procedure is designed to accommodate different aircraft types and operational needs, ensuring efficient and safe landings.
