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 a time deviation between the current time and the scheduled time; and
displaying the time deviation.

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. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A layout for presenting flight information comprising:
-
a time deviation scale having an origin and portions extending on either side of the origin to represent positive and negative values of a time deviation; a time deviation indicator to indicate a point along the time deviation scale to thereby indicate a value of time deviation; a ground speed deviation scale having an origin and portions extending either side of the origin to represent positive and negative values of ground speed deviation; and a ground speed deviation indicator to indicate a point along the ground speed deviation scale to thereby indicate a value of ground speed deviation. - View Dependent Claims (17, 18, 19, 20, 21)
