An aeronautical chart that depicts the aeronautical data required to execute an instrument approach procedure (IAP) to an airport. These charts depict the procedures, including all related data, and the airport diagram. Each procedure is designated for use with a specific type of electronic navigation system, including non-directional beacon (NDB), tactical air navigation aid (TACAN), VHF omnidirectional range (VOR), instument landing system (ILS)/microwave landing system (MLS), and area navigation (RNAV). These charts are identified by the type of NAVAID providing final approach guidance.
