The Hold flight mode causes the vehicle to loiter (circle) around its current GPS position and maintain its current altitude.
:::tip
Hold mode can be used to pause a mission or to help you regain control of a vehicle in an emergency. It is usually activated with a pre-programmed switch. :::
:::note
- This mode requires GPS.
- This mode is automatic - no user intervention is required to control the vehicle.
- RC control switches can be used to change flight modes on any vehicle.
- RC stick movement is ignored.
:::
The aircraft circles around the GPS hold position at the current altitude. The vehicle will first ascend to NAV_MIN_LTR_ALT if the mode is engaged below this altitude.
RC stick movement is ignored.
Hold mode behaviour can be configured using the parameters below.
| Parameter | Description |
|---|---|
| NAV_LOITER_RAD | The radius of the loiter circle. |
| NAV_MIN_LTR_ALT | Minimum height for loiter mode (vehicle will ascend to this altitude if mode is engaged at a lower altitude). |
