**Return to Launch altitude (HGT)** is the predetermined minimum height at which the DeltaQuad Evo will ascend to when initiating a return-to-launch (RTL) procedure. This altitude ensures the vehicle clears obstacles and maintains safe separation from the ground while returning to its landing location.

**Default:** 100 m

{% hint style="warning" %}
The **Return to Launch altitude** value should be set at least **25 meters** above the highest obstacle in the mission area. If the vehicle is below this altitude when an RTL command is triggered, it will climb to the set altitude and then proceed to return. If the vehicle is already above the set altitude, it will continue at its current altitude.

**The Return to Launch altitude is referenced to the takeoff location (HGT), not above ground level (AGL). Special care must be taken when operating in an area with varying ground elevations.**

When an RTL command is triggered, the DeltaQuad Evo will return in a straight line to the designated landing location. Therefore, the vehicle must be capable of flying directly back to the landing point from any point in the mission or flight path.
{% endhint %}

{% hint style="info" %}
The DeltaQuad EVO can perform an autonomous Return to Launch when instructed via the Ground Control Station, initiated from a mission, or triggered by a failsafe event.
{% endhint %}
