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. A system and a method that displays flight information relating to a predetermined flight path are described. 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 when 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. |
