A method is disclosed. The method includes receiving an indication of presence of an aircraft in a vicinity of an uncrewed aerial vehicle (UAV) which is flying along a flight path. The method also includes decelerating, based on the received indication, the UAV to reduce a ground speed along the flight path. The method additionally includes descending, after reducing the ground speed, the UAV to a hover position. The method further includes determining, while the UAV is in the hover position, whether to resume the flight path or to land the UAV based on a determination of continued presence of the aircraft in the vicinity of the UAV. The method also includes controlling the UAV based on the determination of whether to resume the flight path or to land the UAV.

Aircraft systems and methods are provided for assisting sequencing of aircraft by providing conditional estimated arrival times for short arrivals or early clearances. One method involves identifying a geographic location associated with a merge point for an approach to an airport associated with a flight plan for an aircraft, determining an alternative lateral trajectory for the aircraft from a second geographic location along a sequencing route between arrival and the merge point, determining a conditional estimated arrival time for the aircraft at the merge point based at least in part on the alternative lateral trajectory, and transmitting a message including the conditional estimated arrival time for the aircraft to an external computing system.

A management of the elements of the context of one or more flight plans is provided. The systems, methods and computer programs allowing real-time collaborative work on and around one or more flight plans between multiple remote systems are provided. A first system comprises receiving a modification, made on a second system, to a flight plan and to a set of associated objects or to another set of non-associated objects, displaying the modification and, if the modification is validated, returning the modification, as applied to the first system, to the second system to ensure uniformity around the collaborative navigation space between remote parties.

A method includes receiving, by at least one processor, vehicle data associated with at least one journey of a vehicle and indicating at least one implemented vehicle operation used to perform the at least one journey, and receiving, by at least one processor, a vehicle protocol arranged to be used to determine at least one protocol vehicle operation of the at least one journey. The method also includes automatically detecting, by at least one processor, one or more differences between the at least one implemented vehicle operation and the protocol vehicle operation. The differences are associated with the vehicle protocol and feedback information that explains the differences. The feedback information is obtained by using at least one feedback page with requests for the feedback information displayed on a display device. The feedback data is to be used to generate at least one modified vehicle protocol.

Described herein relates to a system and method of optimizing a flight path of an aerial vehicle within an urban air environment. As such, the flight planning system may be configured to provide management and traffic management services to multiple Urban Air Mobility (hereinafter UAM) operators. Additionally, the flight planning system may comprise Low-Altitude Airspace Management Subsystem (hereinafter LAMS), which may generate a nodal network of flyable airspace, routing and/or intersection information for all vertiport pairs, and a Low-Altitude Traffic Management Subsystem (hereinafter LTMS), which may detect and/or may resolve potential conflicts of flight operations and/or may generate at least one conflict-free 4D trajectory. Additionally, the flight planning system may be configured to input at least one flight operation request (e.g., origin vertiport, destination vertiport, departure time, and/or arrival time), such that the flight planning system may generate conflict-free 4D trajectories while evaluating system costs and/or equity among operators.
