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 oper-
ator 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 recom-
mended that the operator take advantage of one of the commercially
available weather radar seminars.
