# Pre-flight Planning

## Weather

* While Astro can fly in the rain, the Ventus OGI camera requires more stable conditions for leak detection, so we do not recommend flying in any precipitation.
* Sensor cooling:
  * It takes approximately 10 minutes for the camera’s cryocooler to reach a stable operating temperature. During this time, the imager may display a cool-down pattern.
* The Astro's operational temperature range is -20C to +50C.

## Checks

* [x] Check that the payload is secured in the Smart Dovetail mount and that the safety latch is closed.
* [x] When you’re ready to fly, perform the standard preflight checks for Astro (found below).

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.freeflysystems.com/ecosystem/payloads/ventus-ogi/operating-handbook/pre-flight-planning.md?ask=<question>&goal=<user_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.
