Aircraft speed guidance display
First Claim
1. A method of displaying flight information relating to a predetermined flight path that specifies locations and scheduled times corresponding thereto, the method comprising the steps of:
- monitoring a current location of an aircraft along the predetermined flight path;
determining a current time at which the aircraft is at the current location;
providing a scheduled time for the aircraft to be at the current location;
calculating, by a processor, a time deviation between the current time and the scheduled time; and
displaying the time deviation on a time deviation scale, the time deviation scale comprising divisions that represent discrete values of time for early and late time deviations of the current time from the scheduled time for the current location, a corresponding time value being displayed in association with each respective division; and
controlling at least one of a thrust of an engine of the aircraft or a configuration of the aircraft in response to the time deviation on the time deviation scale.

Abstract
The invention relates to systems and methods for displaying flight information representative of a deviation from a specified four-dimensional flight path. Particularly, but not exclusively, the invention relates to a cockpit display for enabling pilots to arrive at a particular location at a particular time and to achieve the necessary changes to aircraft speed to achieve a preferred ground speed.
There is described a system and a method that displays flight information relating to a predetermined flight path. The predetermined flight path specifies locations and corresponding scheduled times. A current location of an aircraft along the predetermined flight path is monitored. A current time at which the aircraft is at the current location is determined. A scheduled time for the aircraft to be at the current location is provided. A time deviation between the current time and the scheduled time is calculated. The time deviation is displayed.

8. A system for displaying flight information comprising:
-
a flight path storage memory arranged to store data relating to a predetermined flight path that includes specified locations along the flight path and scheduled times corresponding thereto; a location determination unit arranged to output location data defining a current location of an aircraft along the predetermined flight path; a timer unit arranged to output time data defining a current time at which the aircraft is at the current location; a processor arranged to receive the location data and the time data, to determine a scheduled time from the scheduled times stored in the flight path memory corresponding to the current location, and to calculate a time deviation between the current time and the scheduled time; and a display arranged to display the time deviation on a time deviation scale, the time deviation scale comprising divisions that represent discrete values of time for early and late time deviations of the current time from the scheduled time for the current location, a corresponding time value being displayed in association with each respective division, wherein at least one of a thrust of an engine of the aircraft or a configuration of the aircraft is controlled in response to the time deviation on the time deviation scale. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
