# Search Patterns Operations

## Create Search Pattern

1. Navigate to the NAV Menu, and select SRCH PTTR option. This will open up the SEARCH PATTERN Pop-up menu on the Mission Display.
2. Use the PG UP or PG DN keys, either on the Keyset or MD Bezel, to move the cursor. Press ACK to select a Search Pattern. The FTP Flightplan will now be overwritten with the selected Search Pattern.

3. You may now close the Pop-up by pressing SRCH \*PTTR\*. Adjust Map Range as desired and fly the Search Pattern manually.

All Search Patterns are predefined and non-editable. They all originate from the aircraft location at the time of activation.&#x20;

## Available Search Patterns

* SIERRA SIERRA: Expanding Square
  * Sierra Sierra 10L (10 Legs)
  * Sierra Sierra 15L (15 Legs)
    * The search area is small,
      * &#x20;The location of the search object is known within relatively close
        \
        limits, but some doubt exists about the distress position, and
      * &#x20;A concentrated search is desired
* VICTOR SIERRA: Sector Search
  * Victor Sierra 5NM (5 Nautical Miles per Leg)
  * Victor Sierra 10NM (10 Nautical Miles per Leg)
    * The search area is small,
      * The location of the search object is well known, and
      * A concentrated search is desired.
* CHARLIE SIERRA: Creeping Line Search
  * Charlie Sierra 1NM (1 Nautical Mile spacing between Legs)
    * The search area is large,
      * The location of the search object is approximate, but there is
        \
        a greater chance that the search object is at one end of the
        \
        search area versus the other (i.e. debris was found on one
        \
        end during a previous search), and
      * Uniform coverage is desired.
* PAPA SIERRA: Parallel Search
  * Papa Sierra 1NM (1 Nautical Mile spacing between Legs)
    * The search area is large,
      * The location of the search object is approximate, and
      * Uniform coverage is desired.
