A method and system for displaying aircraft engine information. In one embodiment, the method includes directing the display of an icon that represents an overall operational state of an aircraft engine, with the overall operational state including one of a started state and an unstarted state. The method can further include directing a change in a displayed characteristic of the icon when the overall operational state of the aircraft engine changes from the one of the started state and the unstarted state to the other of the started state and the unstarted state. In a further embodiment, the method can further include repeatedly directing changes in the display of the icon as the aircraft changes from the unstarted state to the started state.
