Helmet-mounted display (HMD) upgrade for the US Army's AVCATT simulation program

The Aviation Combined Arms Tactical Trainer (AVCATT) reconfigurable manned module simulator is the Army's premier deployable helicopter collective training simulator. While successful, improvements to the visual display performance for the Out-The-Window (OTW) visual system have been desired. In a recent selection evaluation, Rockwell Collins' SR100A HMD was chosen for the upgrade, improving display resolution, reducing weight, enhancing comfort and increasing ruggedness. This paper will compare the current XL100A HMD with the improved performance of the new SR100A system.
