Abstract

An avionics display unit for use in a flight management system (FMS) of an aircraft, and a method of using the same to increase a pilot'"'"'s awareness of scheduled changes in operational modes of the aircraft are disclosed. The display unit includes a display device adapted to receive FMS data and to provide a graphical representation of a flight plan for the aircraft relative to a representation of a current position of the aircraft. The display unit is also adapted to provide future mode annunciators, representative of future operational modes of the aircraft, adjacent to positions on the graphical representation of the flight plan at which the future operational modes are scheduled to occur.

Claims

1. An avionics display unit for use in an aircraft, the display unit comprising:

a display device adapted to receive flight management system (FMS) data and to provide a graphical representation of a flight plan for the aircraft relative to a representation of a current position of the aircraft, wherein the display device is also adapted to provide future mode annunciators, representative of future operational modes of the aircraft, adjacent to positions on the graphical representation of the flight plan at which the future operational modes are scheduled to occur;

wherein the display device is further adapted to move the graphical representation of the flight plan and the future mode annunciators relative to the representation of the current position of the aircraft as the current position of the aircraft changes, thereby providing the pilot with an indication of upcoming changes in the operational mode of the aircraft;

wherein the operational modes of the aircraft include at least one of vertical navigational modes, lateral navigational modes, and throttle modes; and

wherein the display device is further adapted to provide, adjacent to particular portions of the graphical representation of the flight plan, representations of scheduled times of arrival of the aircraft at corresponding positions along the flight plan, and thereby providing a display output which correlates the upcoming changes in the operational mode of the aircraft to scheduled arrival times.

2. The avionics display device of claim 1, wherein the display device is further adapted to provide current mode annunciators, representative of current operational modes of the aircraft, adjacent to the representation of the current position of the aircraft.

3. The avionics display device of claim 1, wherein the display device is adapted to cause the future mode annunciators to replace the current mode annunciators when the current position of the aircraft changes such that it corresponds to the positions on the flight plan at which the future operational modes are scheduled to occur.

4. The avionics display device of claim 3, wherein the display device is further adapted to provide a representation of the terrain along the flight plan.

5. The avionics display device of claim 4, wherein the display device is further adapted to provide a representation of a position of air traffic relative to the representation of the current position of the aircraft and relative to the graphical representation of the flight plan.
