Customer: U.S. Marine Corps, Naval Air Warfare Center Training Systems Division (NAWCTSD)

User:  Marine Air Group (MAG) 39 in Camp Pendleton, CA and MAG 29 in New River, NC.

ASI was awarded the AH-1W Weapon Systems Trainer (WST) Technical and Visual Upgrade Program.  The program required updating Devices 2F136A S/N-1 and S/N-2 at MCAS New River, NC and MCAS Camp Pendleton, CA respectively.

The AH-1W WSTs included separate domes for the pilot and co-pilot/gunner, each with their individual cockpit environments and controls. 

The program required the replacement of the current Image generator and databases, replacement of the display system projectors and refurbishment of the existing dome shell structures, host and instructor computer system replacements, upgrade to the existing Tactical Environment (TEn) system, replacement of the motion system control electronics hardware, refurbishment of the existing motion system transducers and servo valves, aural cue and communications system tech refresh and several cockpit block upgrades. ASI also provided a flight dynamic model upgrade to enhance the flying fidelity of the devices.

NVG Stimulation Using Real NVG equipment

–Optimization of database content, illumination and contrast

–Database material coding to support NVG (East and West Coast)

–Simulation of halos around light sources and city glow

–Optimization of projector color, black level and luminance, as well as Gamma values specific to NVG operation

–Christie StiM projectors will use a separate IR illumination, specifically designed to provide the appropriate dark levels for improved NVG training

Projectors operate in a dual OTW/NVG mode with two separate IG channels driving each projector input

–Atmospheric based visibility, with appropriate dependencies on altitude and line of sight

–Light reflection and scattering in clouds

–Continuous time of day, with the Moon rendered in correct position and phase with appropriate effects on scene illumination

–Moon-cast shadows

–Moon illumination from 0-100% in 5% intervals

–Astronomically-correct night sky, including stars and major planets

–Reflections of sun and moon in still waters
