MAP – Displays Full Coverage Ground Map
AUTO – Automatic Weather Presentation Mode
provides detection of windshear out to 5 nm. It
displays turbulence out to 40 nm and weather out to
320 nm. Secondary Weather returns are shown with
black stripes through them. If Hazard Display is
installed, turbulence is extended to 60 nm, and
lightning, hail, and REACT indications are shown.
MAN – Manual Constant Altitude (Weather Analysis)
mode. The altitude slice defaults to current altitude
on MAN selection. It provides detection of
windshear out to 5 nm and displays weather out to
320 nm. If Hazard Display is installed, turbulence is
shown out to 60 nm, and lightning, hail, and REACT
indications are shown.
ALT – Controls weather analysis altitude from 0 to
60,000 ft MSL in increments of 1,000 ft. Selected
altitude is shown on the Electronic Flight Display.
CAL – Rotate to the CAL position for automatic gain
control. The CAL position results in a calibrated
map or weather radar display. Gain control does not
affect turbulence or windshear.
Manual – Rotating knob out of CAL varies gain
between MIN and MAX. VAR is shown on the
display, indicating that the gain has been changed
from the calibrated position.
The MIN position reduces the gain by approximately
16 dBZ below the CAL setting.
The MAX position increases the gain by 10 dBZ over
the CAL setting.
If the Hazard Display Configuration of the radar
system is installed, the GAIN knob can also be used
to temporarily suppress the display of Hazard Icons
and Turbulence Indication. See HAZARD DISPLAY
SUPPRESSION on page 29 for details.
