Which chart furnishes terminal data for IFR flight in congested areas?

The IFR Area Charts are specifically designed to provide pilots with terminal data for Instrument Flight Rules (IFR) operations in congested areas. These charts focus on helping pilots navigate through busy airspace, delivering crucial information such as airspace boundaries, route structures, and navigation aids. They are tailored for use in the environment surrounding airports, particularly where a high density of air traffic is present.

While Standard Terminal Arrival Route Charts are also related to IFR operations, they serve a more specific purpose by detailing the arrival routes that help streamline the process of transitioning aircraft from en-route to approach phases. The Terminal Procedures Publications contain all necessary information including Standard Instrument Departures (SIDs) and Standard Terminal Arrival Routes (STARs), but they are comprehensive documents rather than specific charts for terminal navigation. VFR Sectional Charts are intended for Visual Flight Rules flights, making them unsuitable for the context of congested terminal areas under IFR conditions. Therefore, the IFR Area Charts are the most relevant resource for pilots operating in congested airspace during IFR flights.
