# 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.
Search Patterns Pop-up Menu. Note PG UP, PG DN and ACK Buttons on the right bezel for navigation.
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.
## Available Search Patterns
* SIERRA SIERRA: Expanding Square
* Sierra Sierra 10L (10 Legs)
* Sierra Sierra 15L (15 Legs)
* The search area is small,
* The location of the search object is known within relatively close
\
limits, but some doubt exists about the distress position, and
* 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.

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.miltechsimulations.com/miltech-simulations-mh60/product-guides/other-procedures/search-patterns-operations.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
