If an Initial Approach Fix (IAF) is displayed by name only, what should you do?

When an Initial Approach Fix (IAF) is displayed by name only, it indicates that the specifics of the IAF may not be detailed in the current chart you are looking at. In such situations, it is essential to refer to the appropriate enroute and terminal charts to gather necessary details on the IAF, including its location, altitude restrictions, and any related procedures.

Using the enroute and terminal charts allows pilots to obtain a clearer picture of the airspace structure surrounding the fix, ensuring that they have all the relevant information needed to plan their descent and approach safely and efficiently. These charts often contain critical information about navigation aids, altitude requirements, and procedures that are vital for executing an instrument approach correctly. Thus, referring to the appropriate charts is the best practice in this scenario to ensure safe flight operations.
