MINIMUM TERRAIN
REQUIREMENTS
The airplane's flight path must remain outside of the Minimum
Terrain and Obstacle Clearance requirements in order to pre-
vent a TAWS caution or warning alert. These clearance
requirements will vary depending on the distance from the des-
tination airport or runway, plus other factors such as altitude,
and will decrease as the airplane nears the destination. The
reduction in the clearance requirements allows for the normal
loss of altitude that occurs as the airplane arrives at the desti-
nation. This prevents nuisance cautions and warnings that
may otherwise be received. All alerts are automatically inhib-
ited when the airplane is below 200 feet AGL and within 0.5 nm
of the runway, or is below 125 feet AGL and within 1 nm of the
runway. The following table shows how the minimum terrain/
obstacle clearance requirements change as the airplane
approaches or departs the destination airport.
