Section V. SYSTEMS SIMULATED

TM 55-6930-212-10 Section V. SYSTEMS SIMULATED 2-73. GENERAL. 2-74. The aircraft systems simulated are outlined in the following paragraphs. Simulation details are not provided because each aspect of pseudo real-time simulation is implemented by unique hardware and software programs. 2-75. ACCESSORY SYSTEMS SIMULATION. 2-76. The following aircraft accessory systems provide operational status to the trainee and are simulated by software via computer control: Auxiliary power unit (APU) Instrument indications Engine - fuel Weight and balance Engine - oil Navigation and communication Fuel supply Flight control response Transmission - oil Outside environment Rotor Day, dusk, or night conditions Electrical power system equipment Anti-ice (engine) Hydraulic system (flight and utility) Cargo hooks AFCS 2-77. VISUAL SIMULATION. 2-78. The digital image generation (DIG) provides a full-color visual simulation system (day/night) which displays the following realistic ground and sky conditions: Airfield topography Clear bright sky Flat, low-land topography Cloudy conditions Hilly, mountainous terrain IFR conditions 2-79. SOUND SIMULATION. 2-80. Analog generation under computer control provides the following sound simulation cues: Engine Hydraulic pump (No.1 power transfer unit (PTU)) Transmission Droop stop pounding Rotor Ground start sounds APU Electrical generators 2-81. MOTION SIMULATION. 2-82. An electrohydraulic-actuated, six-post, synergistic six-degree-of-freedom (6-DOF) motion system under computer control provides the following cues: Longitudinal displacement/onset cues Pitch attitude/onset cues Lateral displacement/onset cues Yaw attitude/onset cues Heave displacement/onset cues Turbulence effects Roll attitude/onset cues Rotor out-of-track/balance effects 2-16
