IntuVue RDR-4000 Weather Radar Pilot's Guide
ELEVN – Controls weather analysis altitude from 0 to
60,000 ft in increments of 1,000 ft. Selected altitude
is shown on the Electronic Flight Display. If the pilot's
altitude setting is set to Standard Altitude, the display
will indicate the Flight Level (FL) of the depicted
weather slice. If the altitude setting is QFE/QNH, the
elevation of the weather slice will be given in
thousands of ft (KFT).
AUTO – Rotate to the AUTO position for automatic
gain control. The AUTO position results in a
calibrated map or weather radar display. Gain
control does not affect turbulence or windshear.
Manual – Rotating the knob out of AUTO varies the
gain between MIN and MAX. MAN GAIN 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 AUTO setting;
The MAX position increases the gain by
approximately 10 dBZ over the AUTO setting.
