![Safety - RC Loss (QGC)](../../assets/qgc/setup/safety/safety_rc_loss.png)
The QGCroundControl Safety UI allows you to set the [failsafe action](#failsafe-actions) and [RC Loss timeout](#COM_RC_LOSS_T).
Users that want to disable the RC loss failsafe in specific automatic modes (mission, hold, offboard) can do so using the parameter [COM_RCL_EXCEPT](#COM_RCL_EXCEPT).
The QGCroundControl Safety UI allows you to set the [failsafe action](#failsafe-actions) and [manual control loss timeout](#COM_RC_LOSS_T).
Users that want to disable this failsafe in specific modes can do so using the parameter [COM_RCL_EXCEPT](#COM_RCL_EXCEPT).
Additional (and underlying) parameter settings are shown below.
| 参数 | 设置 | 描述 |
| -------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| <a id="COM_RC_LOSS_T"></a>[COM_RC_LOSS_T](../advanced_config/parameter_reference.md#COM_RC_LOSS_T) | Manual Control Loss Timeout | Time after last setpoint received from the selected manual control source after which manual control is considered lost. This must be kept short because the vehicle will continue to fly using the old manual control setpoint until the timeout triggers. |
| <a id="COM_RC_LOSS_T"></a>[COM_RC_LOSS_T](../advanced_config/parameter_reference.md#COM_RC_LOSS_T) | Manual Control Loss Timeout | Time after last setpoint received from the selected manual control source after which manual control is considered lost. This must be kept short because the vehicle will continue to fly using the last known stick position until the timeout triggers. |
| <a id="COM_FAIL_ACT_T"></a>[COM_FAIL_ACT_T](../advanced_config/parameter_reference.md#COM_FAIL_ACT_T) | Failsafe Reaction Delay | Delay in seconds between failsafe condition being triggered (`COM_RC_LOSS_T`) and failsafe action (RTL, Land, Hold). In this state the vehicle waits in hold mode for the manual control source to reconnect. This might be set longer for long-range flights so that intermittent connection loss doesn't immediately invoke the failsafe. It can be to zero so that the failsafe triggers immediately. |

## 数据链路丢失故障保护
The Data Link Loss failsafe is triggered if a telemetry link (connection to ground station) is lost.
The Data Link Loss failsafe is triggered if the connection to the last MAVLink ground station like QGroundControl is lost.
Users that want to disable this failsafe in specific modes can do so using the parameter [COM_DLL_EXCEPT](#COM_DLL_EXCEPT).

The settings and underlying parameters are shown below.

| -------- | --------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- |
| 数据链路丢失超时 | [COM_DL_LOSS_T](../advanced_config/parameter_reference.md#COM_DL_LOSS_T) | 数据连接断开后到故障保护触发之前的时间。 |
| 故障保护动作 | [NAV_DLL_ACT](../advanced_config/parameter_reference.md#NAV_DLL_ACT) | Disabled, Hold mode, Return mode, Land mode, Disarm, Terminate. |
The following settings also apply, but are not displayed in the QGC UI.
