# Emergency Procedures

### RTL (Return to launch)

Depending on the failsafe settings, certain conditions may trigger the aircraft to go into RTL mode. In this event, unless the pilot knows the reason for the RTL action, it is recommended that the pilot retake control of the aircraft by switching the flight mode (for example: pressing the Loiter Mode button) if possible, in order to evaluate what is happening. If the situation is urgent, the pilot should attempt to land as soon as possible. If the circumstances require the aircraft to return home, the pilot can trigger RTL again via the controller.

### Loss of Orientation

In the event the pilot loses orientation of the aircraft, the pilot should try to center all the joysticks and avoid making big moves. Switch to Loiter Mode. Evaluate the orientation of the drone by giving a small roll command. Verify where the front of the aircraft is to regain control.

### Low Battery

When the battery voltage level drops below the Low Voltage Threshold, the X55 will execute RTL. It’s recommended that the pilot retakes control of the aircraft by switching the flight mode (for example: pressing the Loiter Mode button) and lands the aircraft as soon as possible. If the voltage drops below the Critical Voltage Threshold, the X55 will execute a land command. If the aircraft is in an undesirable location, the pilot may want to retake control of the drone and land the aircraft immediately in a safe location, if possible.

### Loss of Radio Signal

If the connection between the aircraft and the remote controller is lost. The aircraft by default will go into RTL mode. Please refer to the failsafe section to set the appropriate failsafe setting based on your application. The pilot should try to figure out what is causing the lost connection. If the loss of radio signal is due to range, the aircraft will re-connect with the radio controller when it’s within range. The pilot should retake control of the aircraft as soon as possible by switching the flight mode.

### GPS Signal Loss

In the event of GPS signal loss, the aircraft will automatically switch the flight mode to Altitude Hold mode. It is possible that the aircraft is still in Loiter Mode even if the GPS signal degrades. If the pilot observes any unexpected flight behavior, the pilot should switch the flight mode to Altitude Hold Mode and fly the aircraft back to the safe landing area and land the aircraft as soon as possible.

### Unexpected Flight Behavior

If the pilot observes any unexpected flight behavior, the controls should be centered and the flight behavior reevaluated. In most cases, unexpected behavior would be due to false sensor readings, degraded GPS signals, or compass interference. If the aircraft is still behaving unexpectedly, switch to Altitude Hold flight mode and land the aircraft immediately.

### Propulsion System Failure

In the event of a propulsion failure, the pilot should try to steer the aircraft away from people and perform an emergency landing. Bring the throttle down and disarm the aircraft as soon as the aircraft touches the ground. Approach the aircraft with caution.
