Abstract:
1. A simulator for a trainee, comprising: a mock instrumentation apparatus adapted to provide the trainee with realistic simulation controls; at least one projector arranged to project an out-the-window (OTW) image; a helmet-mounted display adapted to be worn by the trainee, wherein the helmet-mounted display includes a viewing surface configured to display a heads-up image; and a dome-like, non-faceted, ellipsoidal projection surface configured to display the OTW image, wherein said projection surface has a vertical dimension which is reduced relative to a horizontal dimension of said projection surface to allow a lower height for said projection surface and is defined by a function of first and second degree continuity, wherein said projection surface generally encloses overhead the trainee and said mock instrumentation apparatus and at least a portion of the projection surface is overhead the trainee, and wherein a focus depth variation between the heads-up image displayed on the viewing surface and the OTW image displayed on the projection surface is less than or equal to 0.2 diopters so as to allow the heads-up image and the OTW image to be merged by the trainee's eyes.
