How does a pilot utilize "chart supplements" in IFR flight planning?

Chart supplements are an essential tool for pilots engaged in IFR flight planning as they provide comprehensive and detailed information about airports and the services available at those locations. This resource is particularly crucial for understanding various aspects of airports, including runway dimensions, lighting systems, taxiway information, and the availability of navigation aids.

Additionally, these supplements include vital operational data, such as communications frequencies, nearby navigational aids, and notes on unique airport procedures or limitations. This depth of information assists pilots in effectively planning their approach to airports, ensuring they have a complete understanding of what to expect when arriving at their destination. By consulting the chart supplements, pilots can enhance their situational awareness and make more informed decisions during flight operations.
