Vertically Scanning A Storm Cell - Garmin G500 Pilot's Manual

Vertically Scanning a Storm Cell

(Not available with all radars)
When vertically scanning with stabilization ON, the actual physical area
that the radar is sweeping may not match the GDU vertical scan display. This
occurs whenever the aircraft pitch is not at 0 degrees. To compensate for this,
the GDU 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 GDU 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.
