Abstract

A method of visually guiding a pilot flying an aircraft using one or more conformal symbols whose position is dynamically updated throughout the guidance is provided herein. The method includes the following stages: determining a desired flight route of an aircraft, based on a user-selected maneuver; presenting to a pilot, on a display, at least one 3D visual symbol that is: (i) earth-space stabilized, and (ii) positioned along a future location along the desired route; computing an updated desired route based on repeatedly updated aircraft flight data that include at least one of: location, speed, and spatial angle, of the aircraft; and repeating the presenting of the at least one 3D visual symbol with its updated location along the updated desired route.
