Reduced RTC Alert Condition
Reduced Required Terrain Clearance (RTC)
The reduced RTC alert condition (Figure 2-32) occurs when the
aircraft is currently above the altitude of the upcoming terrain along
the projected ight path, but the projected terrain clearance is less
than the required terrain clearance (Table 2-9).
The TAWS function issues a caution alert 60 seconds before the
offending terrain and a warning alert 30 seconds before the offending
terrain.
