All F-22 flight simulators at U.S. Air Force mission training centers have now been modernized by Boeing, the company reports.

The upgrade involved the company's high-fidelity Constant Resolution Visual System, which provides pilots a more realistic visual environment than current simulators and allows them to practice extreme maneuvers.

Boeing said the last installations of the Constant Resolution Visual System, or CRVS, were recently performed at Tyndall Air Force Base in Florida.

Other bases with the upgrqade include Hickam Air Force Base in Hawaii, Alaska's Elmendorf Air Force Base and Virginia's Langley Air Force Base.

"The final installation of the Boeing Constant Resolution Visual System improves the realism of ground-based training and increases mission readiness for pilots," said Lt. Col. Matthew Zamiska, 325th Training Support Squadron commander. "This is paramount for Tyndall's mission of training and projecting unrivaled combat airpower."

Boeing's CRVS is found in a variety of other aircraft simulators. Unlike other visual systems, it provides the warfighter with constant target visibility throughout the entire field of vision.
