2-5. TEST CONCEPT.
The UUT test for the TADS NSA is supplemented by procedures in Section III of this chapter, and by
illustrations in Section IV. While you are performing the UUT test, message prompts on the VDT will
direct you to perform one of the procedures in Section III, or to locate a part of the TADS NSA in Section
IV.
a. Procedures. Section III contains procedures to install and remove the TADS NSA and associated
adapters from the nightside test bench, to perform boresight displacement measurement, and to operate
the EETF pneumatic system. These procedures do not apply to the UUT test until called for by the test
program. At the appropriate time during the test, a message prompt on the VDT will direct you to perform
the procedures in one or more paragraphs in this section. At that time, turn to the referenced paragraph
and perform those procedures, as the program cannot continue until they have been performed.
b. Illustrations. Section IV contains illustrations showing different views of the TADS NSA and calling out
components that require some operator action. In addition, the illustrations have warning notes that call
your attention to high voltage, moving fans, and high temperature areas on the TADS NSA. At the
appropriate time during the test, a message prompt will refer to an illustration in Section IV. Turn to the
referenced illustration for assistance while performing the following instructions on the VDT.
2-6. TEST DESCRIPTION.
