      withCompletion:(DJICompletionBlock)completion
      Header:DJIFlightController.h
      SDK Key:DJIFlightControllerKey.DJIFlightControllerParamTripodModeEnabled
      Description:

      Enables/disables tripod mode. Tripod Mode drops the aircraft's maximum speed to 2.2mph (3.6kph), and significantly reduces the control stick sensitivity of the remote controller to give the user the precision needed for accurate framing. When tripod mode is enabled, missions, terrain follow mode, course lock, and home lock are not allowed. Tripod mode is not allowed if the aircraft is running a mission. If GPS or vision positioning aren't available, tripod mode cannot be enabled. If the GPS and/or the vision system is providing the flight controller with velocity information, the aircraft will be able to automatically compensate for wind. If however, position information is not available, manual intervention will be required. User should beware that any manual compensation will be limited due to the reduced maximum velocity and sensitivity. If GPS and vision position become unavailable while in tripod mode, it is advisable to alert the user and disable Tripod Mode.

      Input Parameters:
      BOOL enabledYES to enable tripod mode.
      DJICompletionBlock completionCompletion block that receives the setter result.

      Header:DJIFlightControllerBaseTypes.h
      SDK Key:DJIFlightControllerKey.DJIFlightControllerParamControlMode
      Description:

      Control mode of the flight controller. It determines how the pilot can control the aircraft. By default, it is in smart control mode.

      Enum Members:
      DJIFlightControllerControlModeSmartSmart control mode. The aircraft can stabilize its altitude and attitude in smart mode.
      DJIFlightControllerControlModeManualManual control mode. The aircraft will not stabilize its altitude and attitude in manual mode. This mode is for advanced pilots only, and should only be used when the pilot understands the risk of operating in this mode. Any damage to the product when operating in this mode will not be covered under warranty.
      DJIFlightControllerControlModeUnknownUnknown control mode.

      SDK Key:DJIFlightControllerKey.DJIFlightControllerParamFlightOrientationMode
      Description:

      Tells the aircraft how to interpret flight commands for forward, backward, left and right. See the Flight Controller User Guide for more information.

      Enum Members:
      DJIFlightOrientationModeCourseLockThe aircraft should move relative to a locked course heading.
      DJIFlightOrientationModeHomeLockThe aircraft should move relative radially to the Home Point.
      DJIFlightOrientationModeAircraftHeadingThe aircraft should move relative to the front of the aircraft.

      Description:

      Warning caused by the strong wind.

      Enum Members:
      DJIFlightWindWarningLevel0No wind warning.
      DJIFlightWindWarningLevel1The wind speed is high. Fly with caution and ensure the aircraft remains within the line of sight.
      DJIFlightWindWarningLevel2Strong Wind. Fly with caution and ensure the aircraft remains within line of sight. It is more serious than DJIFlightWindWarningLevel1.

      enum DJIFlightControllerRemoteControllerFlightMode
      typedef NS_ENUM(uint8_t, DJIFlightControllerRemoteControllerFlightMode)
      Header:DJIFlightControllerBaseTypes.h
      Description:

      Flight modes that map to the flight mode switch on the remote controller.

      Enum Members:
      DJIFlightControllerRemoteControllerFlightModePPositioning mode. GNSS and Vision Positioning Systems are used for positioning if they are available. For products without F mode, intelligent functions such as missions and intelligent orientation control can be performed in P-mode.
      DJIFlightControllerRemoteControllerFlightModeSSport mode. The maximum flight speed and responsiveness of the aircraft is increased in this mode.
      DJIFlightControllerRemoteControllerFlightModeAAttitude mode. The GNSS and Vision Positioning Systems are not used for positioning. The aircraft only uses the barometer to maintain altitude. If receiving a GNSS signal, the aircraft can automatically return home if the Remote Controller signal is lost and if the Home Point has been recorded successfully.
      DJIFlightControllerRemoteControllerFlightModeGGentle mode. The sensitivity and speed of aircraft will be substantially decreased in gentle mode.
      DJIFlightControllerRemoteControllerFlightModeMManual mode. The aircraft will not stabilize its altitude nor attitude in manual mode. This mode is for advanced pilots only, and should only be used when the pilot understands the risk of operating in this mode. Any damage to the product when operating in this mode will not be covered under warranty. It is supported by stand-alone A3 and N3 and can be enabled in Assistant 2.
      DJIFlightControllerRemoteControllerFlightModeFFunction mode. Performs the same as Positioning mode with intelligent functions such as missions and intelligent orientation control enabled.
      DJIFlightControllerRemoteControllerFlightModeTTripod Mode. This mode drops the aircraft's maximum speed and significantly reduces the control stick sensitivity of the remote controller to give the user the precision needed for accurate framing. It is only supported by Mavic 2.
      DJIFlightControllerRemoteControllerFlightModeUnknownUnknown mode.

      typedef NS_ENUM(uint8_t, DJIFlightControllerSmartRTHState)
      Header:DJIFlightControllerBaseTypes.h
      Description:

      State of Smart Return-To-Home (RTH). It is only used when Smart RTH is enabled.

      Enum Members:
      DJIFlightControllerSmartRTHStateIdleSmart RTH is not triggered yet in the current flight. The Smart RTH state will be reset to this value when the aircraft lands.
      DJIFlightControllerSmartRTHStateCountingDownSmart RTH is triggered and the aircraft is counting down. If no response is received within 10 seconds or the user confirms the request, the aircraft will start to go home and the state will change to DJIFlightControllerSmartRTHStateExecuted. If user cancels the request, the state will change to DJIFlightControllerSmartRTHStateCancelled.
      DJIFlightControllerSmartRTHStateExecutedSmart RTH is already executed in the current flight. The state will not be reset until the aircraft lands.
      DJIFlightControllerSmartRTHStateCancelledSmart RTH request is cancelled by the user. The state will not be reset until the aircraft lands.
