求翻译：在飞行器自动返航时，可通过遥控器对飞行器进行操控，停止操作（既摇杆回中）继续返航（此时S2模式三档切换开关无效）是什么意思？

正在翻译，请等待...

In 1623, the aircraft automatically through the remote control on aircraft controls to stop the operation (both rocker back in 1623 (AT) Continue to S2 Mode Third Gear Switch is invalid)

Returns from cruise automatically when the flight vehicle, may carry on through the remote control to the flight vehicle holds controls, stops the operation (already rocking bar returning) continues to return from cruise (this time S2 pattern 33 to cut switch invalid)

The aircraft automatically return, with remote control to control the aircraft, stopping operations (rocker) continues to defend (switch S2 model document is invalid at this time)
