What are the three sections of a SID or STAR Chart?

The three sections of a Standard Instrument Departure (SID) or Standard Terminal Arrival Route (STAR) chart are specifically designed to provide pilots with clear and precise information necessary for safe and efficient navigation.

The margin section typically includes important data such as the chart title, data source, version, and other operational notes important for understanding and utilizing the chart appropriately. This information is crucial for pilots as it ensures they have the correct and up-to-date reference material.

The plan view section displays a top-down layout of the route, including waypoints, airways, and any specific route details. This visual representation allows pilots to gain a clear understanding of the path they will follow, both in terms of geography and navigational references.

The textual description section provides detailed instructions on the procedures related to the specific departure or arrival, including altitude restrictions, speed instructions, and any relevant notes that pilots must follow. This written information complements the visual data to ensure clarity and safe navigation.

By combining these three components—margin, plan view, and textual description—the SID and STAR charts deliver comprehensive guidance that pilots need when departing from or arriving at an airport.
