TACTICAL FUNCTIONS
NOTE: The following functions can only be used in aircraft conducting military, para-military, search
and rescue, coast-guard or police operations.
These functions are not covered by any TSO performance standards.
SEARCH PATTERN (If configured)
NOTE: SAR patterns are limited to use under Visual Flight Rules only, unless the aircraft is 2000 feet above all
obstacles within 10 nautical miles of the aircraft flight path.
The CMA-9000 FMS can navigate three types of search patterns from a search fix: expanding square, creeping
ladder and sector search (Figure 1). The parameters of the desired search pattern may either be entered before
take-off or while en-route to the search area. Based on parameters entered, the FMS computes the maximum
ground speed at which the search should be performed. If the aircraft speed exceeds the maximum SAR ground
speed computed, the pattern will not be flown optimally and overshoot will occur. The starting point of the search
pattern is entered as a waypoint. This waypoint may be pre-selected, so that upon reaching it, the CMA-9000
FMS will provide guidance to enter and continue the defined pattern until such time as the pattern is terminated
either automatically or by operator action.
Alternately, the search pattern may be initiated at present position by selecting the PPOS prompt (LSK 5L) on
the RTE x SQUARE, LADDER, or SECTOR 1/X page.
