WEATHER MAPPING AND INTERPRETATION
This section contains general information on use of radar for weather
interpretation. Review of this information will assist the operator in using
radar.
Note: The ability of a weather radar system to display weather returns is
dependent upon the radome Transmission Efficiency. Bendix/King rec-
ommends a 90% average/85% minimum transmission efficiency. Refer
to RTCA document DO-213 Class A for minimum operational perfor-
mance standards for nose mounted radomes.
OBSERVING WEATHER
A weather avoidance radar is only as good as the operator’s interpreta-
tion of the echoes that are displayed on the radar indicator. The operator
must combine knowledge of how radar works and its limitations with
such things as the prevailing weather pattern, and geographic location in
order to make a sound interpretation of the displayed targets.
As a starting point the operator should read FAA Advisory Circular
number 00-24B (Subject: Thunderstorms). It is also highly recommended
that the operator take advantage of one of the commercially available
weather radar seminars.
