METHOD AND SYSTEMS FOR REQUIRED TIME OF ARRIVAL PERFORMANCE DISPLAY
First Claim
1. A required time of arrival (RTA) performance graphic display system for a vehicle, said system comprising:
- a processor programmed to receive predetermined parameters associated with a required time of arrival; and
a first visual display communicatively coupled to said processor, said display comprising an RTA graphic comprising;
a dial comprising an axis;
a first marker indicative of a current estimated time of arrival (ETA) at a predetermined waypoint;
a second marker indicative of a value of the RTA relative to the current ETA value and a selected RTA time tolerance valuea first indication representing a first time the vehicle can attain the predetermined waypoint;
a second indication representing a last time the vehicle can attain the predetermined waypoint;
a third indication representing the uncertainty of the ETA in an early arrival direction; and
a fourth indication representing the uncertainty of the ETA in a late arrival direction.

Abstract
A method and system for a required time of arrival (RTA) performance graphic display is provided. The system includes a processor programmed to receive a required time of arrival and a first visual display communicatively coupled to the processor. The first visual display includes an RTA graphic having a dial substantially symmetric about an axis, a first marker indicative of a current estimated time of arrival (ETA) at a predetermined waypoint, a second marker indicative of a value of the RTA relative to the current ETA value and a selected RTA time tolerance value, a first indication representing a first time the vehicle can attain the predetermined waypoint, a second indication representing a last time the vehicle can attain the predetermined waypoint, a third indication representing the uncertainty of the ETA in an early arrival direction, and a fourth indication representing the uncertainty of the ETA in a late arrival direction.

18. A forward field of view display system comprising a graphic display screen comprising a plurality of indicating areas, at least one indicating area comprising a required time of arrival (RTA) display indicator configured to:
-
graphically display a current estimated time of arrival (ETA) at a predetermined waypoint; graphically display a value of the RTA relative to the current ETA value and a selected RTA time tolerance value; graphically display a first time the vehicle can attain the predetermined waypoint using the fastest current speed limits of the vehicle; graphically display a last time the vehicle can attain the predetermined waypoint using the slowest current speed limits of the vehicle; and graphically display an uncertainty of the vehicle being able to reach the waypoint within the selected RTA time tolerance value. - View Dependent Claims (19, 20, 21)
