A system for providing automatic from-waypoint updating, the system comprising: a display device configured to render images; a variable position user input device configured to supply a signal representative of its position; and a processor in operable communication with the display device and the variable position user input device, the processor coupled to receive a flight plan that includes at least one flight leg (308-1, 308-2) to be captured by an aircraft and at least one waypoint (312-1, 312-2), the at least one flight leg having a start end and a finish end, the at least one waypoint positioned at the start end of the at least one flight leg, the processor further coupled to receive the signal from the variable position user input device, the processor configured to: (i) command the display device to render a lateral map image that includes an aircraft icon and the at least one flight leg to be captured (308-1, 308-2), the aircraft icon rendered at a position on the lateral map that corresponds to current aircraft lateral position and oriented to indicate direction of travel of the aircraft, (ii) command the display device to render a trajectory line graphic that (a) extends from the aircraft icon in a direction that corresponds to the position of the variable position user input device, and (b) intersects the at least one flight leg to be captured (308-1, 308-2), such that if a pilot varies the position of the variable position user input device, the direction in which the trajectory line graphic extends from the aircraft icon will also vary, and (iii) automatically update the flight plan to designate the waypoint at the start end of the at least one flight leg to be captured (308-1, 308-2) as a from-waypoint such that if the position of the variable position user input device is varied such that the trajectory line graphic intersects a different flight leg, the processor will automatically update the flight plan to designate the waypoint at the start end of the different flight leg as a new from-waypoint. a display device configured to render images; a variable position user input device configured to supply a signal representative of its position; and a processor in operable communication with the display device and the variable position user input device, the processor coupled to receive a flight plan that includes at least one flight leg (308-1, 308-2) to be captured by an aircraft and at least one waypoint (312-1, 312-2), the at least one flight leg having a start end and a finish end, the at least one waypoint positioned at the start end of the at least one flight leg, the processor further coupled to receive the signal from the variable position user input device, the processor configured to: (i) command the display device to render a lateral map image that includes an aircraft icon and the at least one flight leg to be captured (308-1, 308-2), the aircraft icon rendered at a position on the lateral map that corresponds to current aircraft lateral position and oriented to indicate direction of travel of the aircraft, (ii) command the display device to render a trajectory line graphic that (a) extends from the aircraft icon in a direction that corresponds to the position of the variable position user input device, and (b) intersects the at least one flight leg to be captured (308-1, 308-2), such that if a pilot varies the position of the variable position user input device, the direction in which the trajectory line graphic extends from the aircraft icon will also vary, and (iii) automatically update the flight plan to designate the waypoint at the start end of the at least one flight leg to be captured (308-1, 308-2) as a from-waypoint such that if the position of the variable position user input device is varied such that the trajectory line graphic intersects a different flight leg, the processor will automatically update the flight plan to designate the waypoint at the start end of the different flight leg as a new from-waypoint.
