# Performance

## Weight and Payload

To determine an aircraft's maximum gross weight, it's important to first determine the pressure, altitude, and temperature at the flight location. Then, consult the weight chart provided. The gross weight includes the weight of the payload, battery, and aircraft structure. 

Remember that the maximum gross weight allowed may exceed the weight limit set by regulatory agencies. Therefore, it's essential to consider any local regulations regarding aircraft weight when planning the aircraft's weight.

## Flight Speeds

| Flight Mode | Speed (m/s)               | Climb (m/s) | Descent (m/s) |
| ----------- | ------------------------- | ----------- | ------------- |
| Position    | 15                        | 4           | 2             |
| Altitude    | no limit                  | 4           | 2             |
| Manual      | no limit                  | no limit    | no limit      |
| Mission     | 7 (default, user setting) | 4           | 2             |
| Return      | 7                         | 4           | 2             |

## **Temperature**&#x20;

The UAS and controller should be flown within 32 degrees F to 104 degrees F. Operating outside of those limits will cause inoperability or can lead to a crash. Ambient temperature is not the same as surface temperature; on a hot day, the outside temp could be 90 degrees F, but a surface could react over 100 degrees F. Keeping all the equipment out of direct sunlight and stored in a cool place is very important on hot days, and keeping the equipment warm on cold days.&#x20;

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.camflite.com/crd1/specs-and-interfaces/performance.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.
