# Performance Set

This asset provides data on the aircraft performance for the trajectory simulation. It is required to enable the simulation and evaluation of a route mission.

{% hint style="success" %}
For even higher simulation precision, Unisphere can provide fine-grained custom performance models based on flight telemetry data. For more information, contact our engineering team: <support@unisphere.de>
{% endhint %}

## Performance Set Dialog

You can create or modify performance sets in the corresponding dialog from the [NOVA Asset Manager](/nova/assets.md#nova-asset-manager).

***

The following parameters are taken into account:

<details>

<summary>Cruise speed [GS/EAS]</summary>

The speed at which an aircraft operates most efficiently during the main phase of flight.

</details>

<details>

<summary>Max speed [EAS]</summary>

The maximum speed an aircraft can safely reach under normal operational conditions.

</details>

<details>

<summary>Rate of climb</summary>

The vertical speed at which an aircraft can ascend, typically measured in feet per minute (ft/min) or meters per second (m/s). It indicates how quickly an aircraft gains altitude and is vital for assessing the performance during takeoff and initial climb phases.

</details>

<details>

<summary>Rate of descent</summary>

The vertical speed at which an aircraft descends, expressed in ft/min or m/s.

</details>

<details>

<summary>Endurance</summary>

The total amount of time a drone can remain airborne, determined by battery capacity and power consumption rate under specific conditions.

</details>

{% hint style="info" %}
**EAS (Equivalent Airspeed)**: The aircraft's speed relative to the air, corrected for altitude and temperature.\
**GS (Ground Speed)**: The aircraft's speed over the ground, affected by wind.
{% endhint %}

{% hint style="info" %}
The performance set is considered only in the evaluation of route missions. Local and multi-location missions ignore the performance set.

# Agent Instructions: 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:

```
GET https://docs.unisphere.io/nova/assets/performance-set.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
