c. The simulator can be released from freeze by insertion of a new IC set or de-
pressing HIT OVERRIDE. However, in the case of an automatically initiated freeze
resulting from the entry of the simulated aircraft into crash conditions, action
must be taken to remove or overcome those conditions before the period of freeze
can be ended. This can be done while the simulator is in freeze by selecting and
inserting a new set of initial conditions preparatory to beginning a new training
activity, thus effectively removing the aircraft from the conditions that led to
the freeze. Alternatively, the instructor can elect to override the crash condi-
tions and permit the flight to continue from the point of crash. When this alter-
native is selected, the simulated aircraft flies out of the crash conditions
following termination of freeze.
d. In addition to standard crash conditions, automatic initiation of freeze
occurs when the simulator threat-scoring algorithm determines that the simulated
aircraft has received a sufficient number of rounds from an enemy weapon that air-
craft systems are degraded to the point where an emergency landing is required and
that landing is unsuccessful. When this occurs, the simulator enters the freeze
state automatically and remains in that state until it is ended by removing the
malfunctions. The instructor can also elect in advance to override the malfunc-
tions associated with the threat algorithm in order to avoid frequent forced land-
ings for an unskilled pilot. This is accomplished by engaging HIT OVERRIDE. When
HIT OVERRIDE is engaged, the effects of being hit, except aircraft degradation,
occur (e.g., sounds and weapons signatures). Scoring and status information is
displayed at the IOS. However, the aircraft continues to be flyable. The in-
structor can elect to override or not override hit or crash conditions.
e. Other events that automatically initiate freeze relate to administrative as-
pects of the simulator instructional process and provide an interruption in the
simulation at points at which a decision must be made concerning the next instruc-
tional activity. No automatic freeze override function is appropriate with respect
to these events, because their occurrence indicates a choice point at which a dif-
ferent activity must be initiated if the simulation is to continue. Such an event
occurs when the simulator is initially made ready for use at the beginning of a
period of instruction and at the end of a segment of recorded flight (e.g., upon
completion of a demonstration or a selected interval of record/playback).
f. Controls for CRASH OVERRIDE and HIT OVERRIDE are alternate-action switch-
lights on the IOS forward control panels (figure 7-4). These switchlights are used
to prevent crash conditions, override a crash condition, and prevent aircraft sys-
tems degradation due to hits.
7-17. INSTRUCTOR VISUAL CONTROL. All controls for monitoring of the visual systems
are on the right side of the forward control panel (figure 7-4). These switch-
lights allow the instructors to monitor different types of displays depending on
the mode of operation.
a. VIS L, VIS FRONT, and VIS R Switchlights. These switchlights allow the in-
structor to select the desired OTW display to be viewed on the overhead DVO/OTW
monitor.
b. Unique CPG IOS Switchliqhts. The following switchlights are at the CPG IOS
only:
