The embodiments disclosed herein present novel and non-trivial system, module, and method for creating a variable FOV image presented on a HUD combiner unit. A processor receives navigation system data and data associated with eye position. A variable FOV image data set representative of navigation symbology is generated, where the image data set is determined by applying the navigation system and eye position data to an adaptive FOV function, where the function correlates eye position to an FOV image. The image data set is presented to a HUD system where an image represented in the image data set is displayed on a combiner unit, whereby the image FOV correlates to eye position. Furthermore, the processor may receive terrain data and generate a variable FOV image data set inclusive of data representative of a three-dimensional perspective scene outside an aircraft.
