Section V. SYSTEMS SIMULATED
2-24. GENERAL. The aircraft systems simulated by the CMS are outlined in the
following paragraphs. Since each aspect of pseudo real-time simulation employs
unique hardware and computer software programs to implement them, simulation de-
tails are not provided.
2-25. ACCESSORY SYSTEMS. The following aircraft accessory systems that provide
operational status to the trainee are simulated by software via computer control:
Instrument indications
Auxiliary power unit (APU)
Weight and balance
Engine - fuel
Navigation and communication
Engine - oil
Armament
Flight controls
Transmission - oil
Outside environment
Power train
Rotor
Day, dusk, or night conditions
Electrical power system
Digital automatic stabilization equipment
(DASE)
Hydraulic system
2-26. SOUND SIMULATION. Analog generation under computer control provides the
following sound simulation cues:
a.
Aircraft Sounds.
The following aircraft sounds are simulated:
Engine
Hydraulic pumps
Transmission
Environmental control system (ECS)
Main rotor
Forward avionics bay (FAB)
Taxi
Aerodynamic airflow
APU
Threat weapons
Crash
b.
Weapon Sounds.
The following weapon sounds are simulated:
Aerial rocket control system (ARCS)
Point target weapon system (Hellfire)
Area weapons (M-230E1, 30-mm cannon)
2-27. MOTION SIMULATION. An electrohydraulic-actuated 6-post synergistic 6-degree-
of-freedom (6-DOF) motion system under computer control provides the following cues:
Longitudinal displacement/onset cues
Lateral displacement/onset cues
Heave displacement/onset cues
Roll attitude/onset cues
Pitch attitude/onset cues
Yaw attitude/onset cues
Turbulence effects
Rotor out-of-track/balance effects
2-28. VIBRATION SIMULATION. An electrohydraulic seat shaker is used to transmit
vibrational effects to the trainees while isolating the effects from other compart-
ment-mounted hardware and occupants.
