Departure and approach procedures for unammed aircraft systems in a visual-flight-rule environment
Journal of aircraft, 2011•arc.aiaa.org
This paper assesses the departure and approach operations of unmanned aircraft systems
in one of the most challenging scenarios: flying under visual flight rules. Inspired by some
existing procedures for (manned) general aviation, some automatic and predefined
procedures for unmanned aircraft systems are proposed. Hence, standardized paths to
specific waypoints close to the airport are defined for departure operations, just before
starting the navigation phase. Conversely, and for the approach maneuvers, a first …

This paper assesses the departure and approach operations of unmanned aircraft systems in one of the most challenging scenarios: flying under visual flight rules. Inspired by some existing procedures for (manned) general aviation, some automatic and predefined procedures for unmanned aircraft systems are proposed. Hence, standardized paths to specific waypoints close to the airport are defined for departure operations, just before starting the navigation phase. Conversely, and for the approach maneuvers, a first integration into a holding pattern near the landing runway (ideally, above it) is foreseen, followed by a standard visual-flight-rule airfield traffic pattern. This paper discuses the advantages of these operations, which aim to minimize possible conflicts with other existing aircraft while reducing the pilot-in-command workload. Finally, some preliminary simulations are shown in which these procedures have been successfully tested with simulated surrounding traffic.
