LANDING ZONE SUITABILITY INDICATING SYSTEM
A system and method of landing an aircraft. The system includes a human machine interface responsive to an input from an operator, and a processor. A region of interest for the aircraft is selected. A representation of a potential landing zone associated with the region of interest is presented at a human machine interface. A suitability of the potential landing zone for landing is evaluated to obtain an evaluation score. The evaluation score for the potential landing zone is presented at the human machine interface. An input is received at the human machine interface to select the potential landing zone. The aircraft is landed at the selected landing zone.
RADAR VECTORING ENERGY MANAGEMENT GUIDANCE METHODS AND SYSTEMS
Methods and systems are provided for guiding or otherwise assisting energy management of an aircraft radar vectoring en route to a runway. A method involves determining a predicted lateral trajectory for the radar vectoring in accordance with interception criteria, wherein the lateral trajectory comprises a sequence of segments for satisfying the interception criteria from a current location of the aircraft and each navigational segment of the sequence is associated with an anticipated aircraft heading assignment. The method determines a reference vertical trajectory corresponding to the lateral trajectory, determines a target value for an energy state parameter of the aircraft at the current location on the lateral trajectory using the reference vertical trajectory, and provides indication of a recommended action to reduce a difference between a current value for the energy state parameter and the target value.
Dynamic radar vectoring guidance methods and systems
Methods and systems are provided for guiding or otherwise assisting energy management of an aircraft radar vectoring en route to a runway. A method involves dynamically determining an updated predicted lateral trajectory for the radar vectoring when the current aircraft status fails to satisfy a trajectory execution criterion for a previously-predicted lateral trajectory by iteratively adjusting a runway interception point defining a segment aligned with the runway until arriving at the updated predicted lateral trajectory for which a stabilization criterion for the runway can be satisfied. The method determines a target value for an energy state parameter of the aircraft at a current location on the updated predicted lateral trajectory and provides indication of a recommended action to reduce a difference between a current value for the energy state parameter and the target value.

Automated air traffic control systems and methods
Automated air traffic control systems and methods may include one or more sensors, such as radar sensors, that are positioned and oriented at opposite ends of a runway. The sensors may detect aerial vehicles on the runway, as well as aerial vehicles within approach corridors at opposite ends of the runway, and other aerial vehicles proximate the runway. Based on data received by the sensors, various characteristics of aerial vehicles can be determined, and instructions for the aerial vehicles can be determined based on the detected characteristics. Then, the aerial vehicles may utilize the determined instructions to coordinate their operations proximate the runway, which may include takeoff, taxiing, and/or landing operations. Further, speech-to-data processing may be used to translate between data and speech or audio input/output in order to enable coordination between unmanned aerial vehicles, manned aerial vehicles, and combinations thereof.
