The software determines when the drift compensation for a detector reaches an
unacceptable level that can compromise detector performance. When a detector reaches
an unacceptable level, the software gives a maintenance warning. Table 36 summarizes
the three levels of AWACS maintenance warnings:
Table 36 Definitions of AWACS Maintenance Levels
Figure 45 contains a graphic representation of the maintenance levels:
