Using a rotary input device to facilitate navigational charting

A method of facilitating the use of a navigational chart. The method is performed by a computer including a display and a rotary input device, e.g. , a mouse wheel. A view of the navigational chart is provided on the display. Movement of the mouse wheel is detected. In response to the movement, the computer uses one or more geographical locations to identify one or more points on the chart, and pans the view in the display to center in the view at least one of the one or more points. This method provides an easy, intuitive way for a pilot or other user to follow a route in a charting application.
