What is the required data for executing an instrument approach to an airport?

The required data for executing an instrument approach to an airport is found in the Instrument Approach Procedure Chart. This chart provides essential information for pilots to conduct a safe and effective instrument approach. It includes critical details such as the approach's procedure, navigational aids, altitudes, and other pertinent data necessary for safely guiding the aircraft during the approach phase of flight.

Having the Instrument Approach Procedure Chart accessible allows pilots to familiarize themselves with the specific requirements and characteristics of the approach they will be using, including any missed approach procedures, communications frequencies, and specific visual references that may be necessary. This chart is fundamental because it directly addresses the operational requirements needed for executing the approach safely in varying weather conditions.

Other materials such as the Airport Information Manual, Flight Information Handbook, and Aeronautical Information Publication provide valuable information about airports, flight regulations, and general aviation information, but they do not contain the specific procedural data needed to conduct an instrument approach effectively. Thus, the Instrument Approach Procedure Chart is the critical document for this task.
