and reduce returns from weather targets. In this
mode, prominent landmarks are displayed
which enable the pilot to identify coastlines,
mountainous regions, cities and even large
structures.
Weather type targets are not calibrated when
the radar is in the GMAP mode. Because of
this, the pilot should not attempt to use GMAP
for weather detection. As a constant reminder
that GMAP is selected, the “GMAP” annun-
ciation is displayed and the color scheme
changes to cyan, yellow and magenta. Cyan
represents the least reflective return, yellow
is a moderate return and magenta is a strong
return.
