Aircraft display systems and methods with flight plan deviation symbology
First Claim
1. An aircraft system comprising:
- a deviation module configured toreceive a flight plan with a flight segment to a waypoint, the flight plan including a lateral profile, a vertical profile, and a time profile, the time profile including a predetermined time of arrival associated with the waypoint,receive a current lateral position and a current altitude,estimate an estimated time of arrival associated with the waypoint,compare the current lateral position to the lateral profile to generate lateral deviation,compare the current altitude to the vertical profile to generate vertical deviation, andcompare the predetermined time of arrival to the estimated time of arrival to generate time deviation; and
a visual display coupled to the deviation module and configured to display deviation symbology representing the lateral deviation, the vertical deviation, and the time deviation,wherein the deviation symbology includesa reference circle, anda first indicator circle that is sized relative to the reference circle to indicate time deviation.

Abstract
An aircraft system includes a deviation module and a visual display. The deviation module is configured to receive a flight plan with a flight segment to a waypoint, the flight plan including a lateral profile, a vertical profile, and a time profile, the time profile including a predetermined time of arrival associated with the waypoint, receive a current lateral position and a current altitude, estimate an estimated time of arrival associated with the waypoint, compare the current lateral position to the lateral profile to generate lateral deviation, compare the current altitude to the vertical profile to generate vertical deviation, and compare the predetermined time of arrival to the estimated time of arrival to generate time deviation. The visual display is coupled to the deviation module and configured to display deviation symbology representing the lateral deviation, the vertical deviation, and the time deviation.

13. A method of displaying deviation symbology comprising the steps of:
-
receiving a flight plan with a flight segment to a waypoint, the flight plan including a lateral profile, a vertical profile, and a time profile, the time profile including a predetermined time of arrival associated with the waypoint; receiving a current lateral position and a current altitude; estimating an estimated time of arrival associated with the waypoint, comparing the current lateral position to the lateral profile to generate lateral deviation; comparing the current altitude to the vertical profile to generate vertical deviation; comparing the predetermined time of arrival to the estimated time of arrival to generate time deviation; and displaying fused deviation symbology representing the lateral deviation, the vertical deviation, and the time deviation, wherein the displaying step includes displaying a reference circle and a first indicator circle that is sized relative to the reference circle to indicate time deviation. - View Dependent Claims (14, 15, 16)
