Once you select the Fly option from the mission planning screen, Site Scan will go through a series of checks to make sure that the aircraft is ready to take off.&#x20;

Once these checks are finished, Site Scan will prompt you once again to check your takeoff point and give the aircraft permission to start the mission.&#x20;

Now that the aircraft is flying, you will have telemetry along the top of the screen. From left to right, the telemetry is as follows: Distance from the home point, altitude, charge of batteries, and satellites in range. \

You can switch between a variety of views while the mission is in progress.&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.freeflysystems.com/astro/other-user-manuals/ecosystem/esri-arcgis-flight-site-scan/3-flying-a-mission-with-astro.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
