Which SIDs do not include departure or transition routes?

• A. Pilot Navigational SIDs
• B. Vector SIDs
• C. Standard SIDs
• D. Obstructed SIDs

Answer: (B)

Vector SIDs are specifically designed to provide air traffic controllers with the authority to guide departing aircraft along a predetermined route using radar vectors rather than fixed waypoints or transition routes. This flexibility allows controllers to manage air traffic efficiently, especially in busy airspace, as they can adapt the departure path based on current traffic conditions rather than being confined to specific navigational procedures. In contrast, Pilot Navigational SIDs, Standard SIDs, and Obstructed SIDs typically include defined departure or transition routes that pilots must follow. Pilot Navigational SIDs rely on the aircraft's own navigation systems, using waypoints that are predetermined. Standard SIDs offer a standardized route for departures to ensure consistency and safety. Obstructed SIDs are specifically designed to avoid obstacles, which inherently includes predefined routes. Thus, Vector SIDs are the only type that allows for more direct, on-the-fly routing guided by air traffic control without a set departure path.
