METHODS AND SYSTEMS FOR INDICATING FUEL REQUIRED TO REACH A LOCATION
First Claim
1. A method for indicating on a display device whether a vehicle has sufficient fuel remaining to travel from a first location to a second location, the method comprising:
- determining a first amount of fuel required for the vehicle to travel from the first location to the second location;
if the first amount of fuel required is greater than a threshold fuel value associated with the first location, displaying a graphical representation of the second location on the display device using a first visually distinguishable characteristic; and
if the first amount of fuel required is less than the threshold fuel value, displaying the graphical representation of the second location on the display device using a second visually distinguishable characteristic.

Abstract
Methods and systems are provided for indicating on a display device whether a vehicle has sufficient fuel remaining to travel from a first location to a second location. An exemplary method involves determining the amount of fuel required for the vehicle to travel from the first location to the second location. If the amount of fuel required is greater than a threshold fuel value associated with the first location, the method displays a graphical representation of the second location on the display device using a first visually distinguishable characteristic. If the first amount of fuel is less than the threshold fuel value, the method displays the graphical representation of the second location on the display device using a second visually distinguishable characteristic.

12. A method for displaying a waypoint on a display associated with an aircraft, the method comprising:
-
calculating a required amount of fuel for the aircraft to travel from a current position of the aircraft to a destination position associated with the waypoint; if the required amount of fuel is greater than a current amount of fuel onboard the aircraft, displaying an image of the waypoint on the display using a first visually distinguishable characteristic; and if the required amount of fuel is less than the current amount of fuel onboard the aircraft, displaying the image of the waypoint on the display using a second visually distinguishable characteristic. - View Dependent Claims (13, 14, 15, 16, 17)

18. A display system for use in an aircraft, the display system comprising:
-
a display device associated with the aircraft, the display device being adapted to display a graphical representation of a waypoint; a navigation system adapted to determine a current position of the aircraft; and a flight management system coupled to the display device and the navigation system, the flight management system being configured to; calculate a required amount of fuel to travel from the current position of the aircraft to a location associated with the waypoint; render the graphical representation of the waypoint on the display device using a first visually distinguishable characteristic if the required amount of fuel is greater than a current amount of fuel onboard the aircraft; and render the graphical representation of the waypoint on the display device using a second visually distinguishable characteristic if the required amount of fuel is less than the current amount of fuel onboard the aircraft. - View Dependent Claims (19, 20)
