1. A flight simulator for training a user to operate an aircraft, comprising:
a primary display system to simulate a first view outside a window of the aircraft, comprising:
a primary screen operable to display a first image; and
a primary mirror configured to reflect the first image at substantially infinity focus to a designated eye point of the flight simulator, the primary display system having a first vertical field of view (FOV) measured at the designated eye point; and
a secondary display system operable to simulate a second view outside the window of the aircraft, comprising:
a second screen operable to display a second image;
a second mirror configured to reflect the second image from the second screen to the designated eye point such that at least a portion of the second image is at substantially infinity focus, the secondary display system having a second vertical FOV measured at the designated eye point of at least 20°, the primary display system and the secondary display system being aligned vertically and horizontally to provide a combined image defined by the first image and the second image, wherein the combined image comprises a substantially continuous vertical FOV measured at the designated eye point of at least approximately 80°, and wherein the combined image has a collimation gradient that varies from infinity to less than infinity.
