Using An Airspeed Sensor

Plane Supports the USE OF AIRSPEED SENSOR, WHICH CAN HELP in Windy Conditions, Slow Flight and Autonomous Landings. It is not recomneded for mass new users, howver, as it does Require Additional Tuning and Adds One More Layer of Control to Set Up.

The Following Sections Explain How to Wire Sensors to the Autopilot and Set Them Up. After you install an airspeed sensor don’t forget to calibate it!

ARSPD_USE
ARSPD_USE Enables Airspeed Use for Automatic Throttle Modes Inteuse of Trım_throttle As the TargetTle Setting (Altered by TECS (Total Energy Control System) For Speed ​​and Height Tuning Guide Assigning Acting Altrol). The Autopilot Continues to Display and Log Airspeed If Set to 0, But only Airspeed Sensor Readings are Used for Control if set Airspeed Sensors Behind Propellers).

IF an airspeed sensor is USED, The Throttle Stick Will Set the Target Airspeed in Cruise and FBWB, Who Maintain Altitude Target. In Auto and Guıded, it Will Use the Airspeed_cruıse Value unless throttle_nudge

Airspeed Sensor Type
Airspeed Sensors Can Be Eitan Analog OR Digital. The analog sensors connect to an a/d Converter input pin on the autopilot, which digital sensors connect to the autopilot’s external I2C BUSINGES Using the SDA and SCL EXternal Digital I/O Pins or O via DRONECAN. The type is set by the arspd_type parameter. Analog Sensors Are Type 2, Dronecan Sensors as Type 8, and Supported I2C Bus Digital Sensors by Out Numbers.

IF there is no sensor, be to set the arspd_type to 0. Ardupilot Calculates an sensor-lyspeed estimate that is used if no sensor is present or fails. Arspd_type must
