Which chart primarily contains information relevant to IFR arrival and departure phases?

The chart that primarily contains information relevant to IFR (Instrument Flight Rules) arrival and departure phases is the Terminal Chart. This type of chart is specifically designed for use in the vicinity of airports, providing crucial data necessary for aircraft during the approach to landing and takeoff. Terminal Charts include detailed information such as Standard Terminal Arrival Routes (STARs), Standard Instrument Departures (SIDs), and other procedural information essential for navigating safely in and out of busy terminal airspace.

While other chart types like VFR Navigational Charts, Canada Air Pilot (CAP), and Enroute Low Altitude Charts serve important purposes, they do not focus exclusively on the specific needs of IFR operations during arrival and departure phases. For instance, VFR charts are aimed at visual flight rules and are more suited for pilots flying without relying on instruments. The Canada Air Pilot primarily caters to navigation in Canadian airspace and includes a variety of information but is not solely dedicated to IFR arrivals and departures. Enroute Low Altitude Charts are designed for navigation during the enroute phase of flight, not the approach and departure phases around airports. Thus, the Terminal Chart stands out as the most relevant for IFR operations in these critical phases.
