What is the primary purpose of the IAP Chart?

The primary purpose of the Instrument Approach Procedure (IAP) Chart is to display aeronautical data that is critical for safely guiding aircraft during the approach phase to an airport under instrument flight rules (IFR). IAP charts include essential information such as the specific flight paths for approaches, aiding pilots in understanding how to safely descend and align their aircraft with the runway. They provide details like the altitude and speed restrictions, visual references, navigational aids, and missed approach procedures, ensuring that pilots have comprehensive guidance for landing in varying visibility and weather conditions. By focusing on this data, the IAP Chart plays a crucial role in maintaining safety and efficiency in air traffic operations.
