Section V. SYSTEMS SIMULATED
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)
Engine - fuel
Weight and balance
Engine - oil
Navigation and communication
Flight control response
Transmission - oil
Day, dusk, or night conditions
Electrical power system equipment
Hydraulic system (flight and utility) Cargo hooks
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:
Clear bright sky
Flat, low-land topography
Hilly, mountainous terrain
2-79. SOUND SIMULATION.
2-80. Analog generation under computer control provides the following sound simulation cues:
Hydraulic pump (No.1 power transfer unit (PTU))
Droop stop pounding
Ground start sounds
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
Roll attitude/onset cues
Rotor out-of-track/balance effects
