Comparing Regain Well Clear Guidance

Minimum Detect and avoid Well Clear (DWC) guidance provides the pilot with information on the directions in which DWC is predicted to be lost and how soon. Different guidance algorithms are analyzed for their ability to provide guidance after DWC is lost. Command and status-based concepts for guidance to regain-DWC in case the loss was not prevented are compared from a conceptual, regulatory and performance perspective. The guidance decisions and associated performance are analyzed using TCPA-DCPA traces and guidance band time-histories. Based on the results, recommendations are provided.
