Weather Radar Overview - Honeywell Bendix/King KMD 850 Pilot's Manual Addendum

WEATHER RADAR OVERVIEW

The radar display has been calibrated to show five levels of target inten-
sity: Black (level 0), Green (level 1), Yellow (level 2), Red (level 3), and
Magenta (level 4). The meaning of these levels is shown in the following
chart as to their approximate relationship to the Video Integration
Processor (VIP) intensity levels used by the National Weather Service.
These levels are valid only when; (1) the Wx mode is selected; (2) the
displayed returns are within the STC range of the radar; (3) the returns
are beam filling; (4) there are no intervening radar returns.
