display of the surrounding terrain on the Weather Radar
Indicator, EFIS, or a dedicated display. Based on the
aircraft's position and the internal database, the terrain
topography (within the display range selected) that is
above or within 2000 feet below the aircraft altitude is
presented on the system display. This feature is an option,
enabled by program pins during installation.
additional terrain display features for enhanced situational
awareness, independent of the aircraft's altitude. This
includes digital elevations for the highest and lowest
displayed terrain, additional elevation (color) bands, and a
unique representation of 0 MSL elevation (sea level and
its corresponding shoreline). This feature is an option,
enabled by program pins during installation.
objects for obstacle conflict alerting and display.
Additionally, when TAD is enabled, Obstacles are
graphically displayed similar to terrain. This feature is an
option, enabled by program pins during installation.
airport approach and departure profiles to tailor EGPWS
alerts at certain geographic locations to reduce nuisance
alerts and provide added protection.
additional element of protection by alerting the pilot of
possible premature descent. This is intended for non-
precision approaches and is based on the current aircraft
position relative to the nearest runway. This feature is
enabled with the TAD feature.
circular band similar to the TCF feature except that RFCF
is based on the current aircraft position and height above
the destination runway based on Geometric Altitude (see
next page) and only extends 5 NM past the end of the
runway. This provides improved protection at locations
where the destination runway is significantly higher than
the surrounding terrain. (In -210-210 and later versions).
