Filed:

Dec 10, 2020

Appl. No.:

17/117340

Inventors:

- Cedar Rapids IA, US
Keith M. Allen - Centreville VA, US

Assignee:

Rockwell Collins, Inc. - Cedar Rapids IA

International Classification:

G08G 5/00

Abstract:

A system and method are disclosed. The system includes a computer readable medium having non-transitory computer readable program code embodied therein for risk-aware contingency flight re-planning. The computer readable instructions include instructions, which when executed by a computer device or processors, perform and direct the step of receiving a preplanned route, receiving a risk tolerance level from a decision maker, receiving input from a database, receiving an indication of an en route risk to the vehicle, determining an association of an exposure cost with at least one of a plurality of 4-D paths, ranking the plurality of 4-D paths based on the association of the exposure cost, and displaying a portion of the plurality of 4-D paths to the decision maker.

Abstract:

A collision avoidance system includes a processor configured to determine first and second positions of an intruder in first and second images, respectively, determine an angular position change of the intruder by comparing the first and second positions, determine a rate of change of a line of sight angle from an aircraft to the intruder based on the angular position change and a time between the first and second images, determine a rate of change of the angular size of the intruder based on a difference in angular size of the intruder from the first to second image and the time between the first and second images, and provide an alert to an operator of the aircraft in response to the ratio of the rate of change of the line of sight angle and the rate of change of the angular size of the intruder being less than a threshold.
