CHAPTER 2 SIMULATOR AND SYSTEMS DESCRIPTION AND OPERATION

TM 55-6930-212-10 CHAPTER 2 SIMULATOR AND SYSTEMS DESCRIPTION AND OPERATION Section I. GENERAL 2-1. OPERATIONAL SYSTEM. 2-2. The CH-47D Flight Simulator is a fixed-base simulator for training pilots in the use of CH-47D (Chinook) helicopters. Training is conducted in the instructor/ trainee station which is equipped with visual display systems. The station is mounted on a six-degree-of-freedom hydraulic motion system and is controlled by a central computer system. The areas of the simulator complex are described further in the following paragraphs. 2-3. SIMULATOR COMPARTMENT. 2-4. The simulator compartment houses a cockpit station in the forward position and an instructor operator station (IOS) and it provides visual, motion, and sound simulation. (See figure 2-1 for the flight compartment layout.) 2-5. The trainee station is a replica of the actual aircraft cockpit. It includes facsimiles of the cockpit windows, pilot seat, main instrument and control panel, flight controls, chin window, and copilot seat. Left and right power distribution panels are actual aircraft parts. 2-6. All controls, indicators, and panels are simulated, and they are identical to those in TM 55-1520-240-10, Operator's Manual for the CH-47D Chinook Helicopter. 2-7. Three pairs of loudspeakers and one subwoofer in the simulator compartment provide realistic aural cue sounds. The sound characteristics are correct with respect to location, frequency, and loudness (within safety limits). The instructor can vary the loudness of the cue sounds. 2-8. The trainee cockpit seats can be vibrated to simulate continuous and periodic oscillations and vibrations that crew members experience during actual flight conditions and maneuvers, and also vibrations that represent progressive malfunctions. Seat vibration is isolated from the rest of the simulator compartment by means of damping elements in the seat mounting. 2-9. The ambient temperature of the simulator compartment and cockpit is controlled by adjusting the thermostat on the compartment right wall. Conditioned air is pumped through the compartment area and the helicopter cockpit heating and defrosting ducts. 2-10. Cockpit environment control system switches and controls are nonfunctional. 2-11. INSTRUCTOR OPERATOR STATION. 2-12. The instructor operator station (IOS) is in the simulator compartment, adjacent and to the rear of the cockpit. (Refer to Section II for further details.) Using the IOS, the instructor operator can control the training program and monitor and evaluate trainee performance effectively. (See figures 2-2 and 2-3 for the instructor station layout and IOS controls.) 2-1
