1. A method comprising:
receiving a landing request from an aircraft at a ground control center of a vertiport;
activating one or more infrared cameras located at a landing site of the vertiport when the received landing request is approved by the ground control center;
searching for the aircraft based on one or more light strobes located on the aircraft using the one or more infrared cameras;
creating a virtual current approach frame of the aircraft when the light strobes are detected by the one or more infrared cameras;
comparing the virtual current approach frame to a predefined approach frame stored by the ground control center to determine whether a landing approach of the aircraft is suitable to provide a safe landing for the aircraft;
if the landing approach of the aircraft is not suitable, sending correctional feedback information to the aircraft from the ground control center to provide corrected guidance for the landing approach based on a difference between the predefined approach frame and the virtual current approach frame; and
projecting a conical area for aircraft detection, the conical area including a set of virtual approach rings each having predicted approach threshold values based on aircraft parameters.
