APOLLO MISSION SIMULATOR INSTRUCTOR HANDBOOK 1.3.1 SIMULATOR SUPPLEMENTARY CONTROLS AND DISPLAYS.

Those IOS controls and displays that are other than spacecraft repeater instruments can be generally identified in two groups.

1. Those controls and displays used by the instructor-operator to operate the simulator and monitor the status of simulator systems.

2. Those displays, other than repeater instruments, that are used by the instructor-operator to monitor crew performance.

The IOS panels containing such simulator controls and supplementary displays are identified in the following illustrations. Controls and indicators located, thereon, are functionally described in the associated tables.

1.3.1.1 G&N Supplementary Displays.

The nature of flight crew operation of the simulated G&N system is such that IOS repeater instruments do not provide sufficient visibility for effective instructor-operator monitoring. For this reason, the G&N system repeater instruments have been augmented with the following supplementary displays (figure 1-4) functionally described in table 1-3.

Panel 16 The mark error panel provides indication of SCT positioning error during a navigation sighting in the angular coordinates of the landmark with respect to the telescope crosshairs.

Panel 18 The orbital position panel provides an indication of vehicle longitude, latitude and altitude.

Panel 19 This panel displays navigational parameters. Three of the displays provide celestial coordinates for the sextant's landmark line-of-sight indicated in sidereal hour angle, declination, and rotation angles. The other two displays are shared between the SCT and SXT. In midcourse, the sextant's star LOS sidereal hour angle and declination are indicated. In orbit, the intersection point coordinates of the telescope line-of-sight with respect to earth or moon are indicated.

Panel 20 This panel is a 5-inch CRT display of SXT/SCT error signals. Respective fields-of-view are manually controlled with respect to a small circle as the landmark representation.

Panel 21 The true spacecraft attitude panel provides readouts of attitude rate and position as reference to the indicated reference frame.

1.3.1.2 Navigation Evaluation Panel

The controls and indicators on this panel relate to the fuel consumed during a navigation sighting maneuver. The mark hold and release controls provide 1-34
