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.
