TM 55-6930-212-10 Section II. INSTRUCTOR OPERATOR STATION DESCRIPTION 2-35. GENERAL DESCRIPTION. 2-36. The instructor operator station (IOS) accommodates one instructor and an observer. Figure 2-1 shows the arrangement of the IOS and its relationship to the trainee station. This arrangement permits close, direct contact between the instructor operator and the trainees. The locations of the forward control panel and the console control panel provide convenient control of the cockpit and direct contact with the cathode ray tube (CRT) informational displays that are required to monitor, guide, and evaluate trainee performance. Various features of the instructor areas are described in the following paragraphs. 2-37. IOS CONTROL PANELS. 2-38. The instructor station is in the cockpit behind the pilot and copilot seats. This over-the-shoulder location reduces the requirement for a remote visual repeater for the instructor. Two 19-inch displays at the instructor station and two control panels are available to the instructor. Units of the instructor station are: Aft instructor CRT Forward instructor CRT Instructor left panel Instructor right panel Interphone control panel (in cabinet under forward CRT) Digital clock 2-39. Flight and mission parameters are displayed on the aft CRT. The instructor can make changes to parameters during flight and can introduce malfunctions using the control panels. 2-40. IOS AREA LIGHTING. 2-41. The IOS control panel has two variable-intensity overhead lights. These lights provide ambient illumination during any phase of the training and can be detached for greater flexibility. A blue-green flip filter is provided for NVG operation. 2-42. INSTRUCTOR INTERCOMMUNICATIONS SYSTEM. 2-43. Headset cords and microphone switches for the instructor are installed in such a way that they do not interfere with training. Private communication is provided for the instructor, observers, and the computer room. A visual alert cue is provided for the instructor, and an aural alert cue is provided in the computer room. 2-7
