Vertically Scanning A Storm Cell - Garmin GTN 650 Series Pilot's Manual Upgrade Supplement

5.5.3

Vertically Scanning a Storm Cell

When vertically scanning with stabilization ON, the actual physical area
that the radar is sweeping may not match the vertical scan display. This occurs
whenever the aircraft pitch is not at 0 degrees. To compensate for this, the vertical
display will "erase" the portion of the vertical display that is no longer being
scanned. It will appear that the vertical sweep "wraps around" when reaching
the end of the GTN vertical display. The radar is simply "erasing" the portion of
the vertical display that is not currently being scanned.
NOTE: Vertical scanning of a storm cell should be done with the aircraft
wings level to avoid constant adjustment of the Bearing Line.
