Section V. SYSTEMS SIMULATED

TM 55-6930-214-10

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

Fuel supply

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:

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

Electrical generators

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.
