. Up to eight weather and sea-current observations
can be entered into NAVSAR. Sea-current observations
that do not include the wind current need wind-speed
and -direction observations prior to the time of the
sea-current observation. Ideally, wind-speed and
-direction observations representing conditions 48
hours before the sea-current observation should be
entered. If there are no sea- or wind-current
observations, sources of sea-current data consists of
Fleet Numerical Meteorological and Oceanographic
Center (FNMOC) monthly current charts and the Naval
Oceanographic
Office
(NAVOCEANO)
surface-current atlases.
l A maximum of five search assets can be entered
on the status board for a particular search.
. Up to five search object probability maps can be
requested for display in sequence.
. A maximum of five search plans can be added to
the status board.
. NAVSAR computes the sweep widths for both
visual and electronic search sensor types. For any other
sensor types, the user must provide the sweep width.
l The searching altitude to enter for aircraft is the
flight altitude; for ships, it is the bridge height or the
height of the sensor.
. Search object location maps can only be
produced after the earliest distress scenario date-time
group (DTG).
FUNCTIONAL DESCRIPTION
NAVSAR can be subdivided into three main
functions:
1. The status board maintenance function performs
the data base management.
2. The map generation function purpose is to
produce probability maps for the search object at
user-entered times based on the data available in the
current status board.
3. The search planning function is to provide
search plan recommendations that allow the most
effective use of the available search assets.
