Methods and systems for taxiway traffic alerting
First Claim
1. A method performed by a system located on an ownship, the method comprising:
- at a processing device,determining whether the ownship is on the ground based upon a weight-on-wheels signal;
determining, in response to determining that the ownship is on the ground, whether the ownship is in motion;
receiving, in response to determining that the ownship is in motion, information from a ground traffic vehicle;
receiving, in response to determining that the ownship is in motion, ownship information;
determining a distance by which the ground traffic vehicle will pass the ownship after reaching an estimated full-stop location of the ownship based on the received ownship information and one or more predefined constants, the predefined constants comprising a flight crew reaction time and a flight crew action time;
generating a potential collision alert if the determined distance is less than a predefined safe distance value, the safe distance value calculated based upon a wingspan of the ownship and a wingspan of the ground traffic vehicle; and
at an exterior lighting device, providing illumination towards the ground traffic vehicle after generation of the potential collision alert.

Abstract
Systems and methods for providing the crew of a vehicle with a potential collision alert. The alert is based on presumed flight-crew action and reaction times, ownship speed, and required distance to safely stop the ownship before intersection with traffic. An exemplary system located aboard an ownship includes a communication device that receives information from a ground traffic; a memory device that stores ownship information and predefined constants; and a processing device that determines a distance to the traffic when the traffic passes the ownship after the ownship stops at a estimated full-stop location, based on the received ownship information and the predefined constants, determines distance to the ground traffic vehicle, based on the determined point in time, and generates a potential collision alert if the determined distance is less than a predefined safe distance value. An exterior lighting device outputs a visual illumination after the potential collision alert is generated.

8. A system located aboard an ownship, the system comprising:
-
a communication device configured to receive information from a ground traffic vehicle; a memory device configured to store ownship information and one or more predefined constants, the predefined constants comprising a flight crew reaction time and a flight crew action time; a processing device in signal communication with the communication device and the memory device, the processing device configured to; determine whether the ownship is on the ground based upon a weight-on-wheels signal; determine, in response to determining that the ownship is on the ground, whether the ownship is in motion; determine, in response to determining that the ownship is in motion, a distance by which the ground traffic vehicle will pass the ownship at an estimated full-stop location of the ownship based on the received ownship information and one or more predefined constants; generate a potential collision alert if the determined distance is less than a predefined safe distance value, the safe distance value calculated based upon a wingspan of the ownship and a wingspan of the ground traffic vehicle; and an exterior lighting device configured to provide illumination towards the ground traffic vehicle after generation of the potential collision alert. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A system located on an ownship, the system comprising:
-
a means for determining whether the ownship is on the ground, the means generating a weight-on-wheels signal; a means for determining, in response to determining that the ownship is on the ground, whether the ownship is in motion; a means for receiving information, in response to determining that the ownship is on motion, from a ground traffic vehicle; a means for receiving ownship information; a means for determining a distance by which the ground traffic vehicle will pass the ownship at an estimated full-stop location of the ownship based on the received ownship information and one or more predefined constants, the predefined constants comprising a flight crew reaction time and a flight crew action time; a means for generating a potential collision alert if the determined distance is less than a predefined safe distance value, the safe distance value calculated based upon a wingspan of the ownship and a wingspan of the ground traffic vehicle; and a means for directing a visual illumination toward the ground traffic vehicle after generation of the potential collision alert. - View Dependent Claims (19)
