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;
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 predetermined waypoint is attainable by the vehicle;
a second indication representing a last time the predetermined waypoint is attainable by the vehicle;
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, anda second visual display communicatively coupled to said processor, said second display comprising a map mode graphic comprising;
an RTA time box comprising a length indicative of a relative time between the first time and the last time;
a vehicle symbol including an indicia corresponding to the current ETA; and
an RTA symbol indicative of a time the vehicle is required to cross a predetermined waypoint.

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.

13. A method of displaying a required time of arrival (RTA) performance comprising:
-
receiving waypoint information, including waypoint position information, a required time of arrival (RTA) of a vehicle at the waypoint, a tolerance about the RTA, and an estimated time of arrival (ETA) at the waypoint; and graphically displaying on a first electronic visual display the RTA relative to the ETA indications representing times the predetermined waypoint is attainable by the vehicle, and indications representing the uncertainty of the ETA; and graphically displaying on a second electronic visual display, a map mode graphic comprising;
an RTA time box comprising a length indicative of a relative time between a first time the wavpoint is attainable by the vehicle and a last time the waypoint is attainable by the vehicle, a vehicle symbol including an indicia corresponding to the current ETA; and
an RTA symbol indicative of a time the vehicle is required to cross the waypoint. - View Dependent Claims (14, 15, 16)

17. 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 on a map mode graphic; a current estimated time of arrival (ETA) at a predetermined waypoint; a value of the RTA relative to the current ETA value and a selected RTA time tolerance value; a first time the predetermined waypoint is attainable by the vehicle using the fastest current speed limits of the vehicle; a last time the predetermined waypoint is attainable by the vehicle using the slowest current speed limits of the vehicle; and an uncertainty of the vehicle being able to reach the waypoint within the selected RTA time tolerance value, and a color-coded alert indicating whether the aircraft is outside of the selected RTA time tolerance value. - View Dependent Claims (18, 19, 20)
