3.4.3 Custom/Advanced Sensor Setup

In the Custom/Advanced Sensor Setup you can select your source of sensor data by selecting a Sensor Interface and pressing "Use".

Currently the following Sensor Interfaces are available:

- Official SensorFusion: Provides the current aircraft's attitude, position, altitude,... given that you are using good sensors (e.g. good internal sensors or an external SensorBox). It is also possible to connect to the radios of the external SensorBox and thereby receiving ADS-B, Localizer and Glideslope information.

- Logfile: Replays sensor data from a logfile. This causes Horizon to look like during the flight in which the Logfile was recorded.

- UDP (forwarded data): Receives sensor data from another tablet/smartphone.

- FlyBox Autopilot + Sensors: Receives attitude, position and sends procedure deviation information to/from the FlyBox Autopilot System: Horizon soon has the ability to connect to an autopilot to provide procedure deviation hints. The Autopilot then may decide to control the aircraft according to the deviation from the current flight plan / procedure. Please note that Horizon itself does not control or steer anything. The decision how to control the aircraft is done by the autopilot and the pilot in command.
Soon the Autopilot from FlyBox Avionics (http://www.flyboxavionics.it/) is going to be supported. It then can be set up in the 'Sensor Setup' (Menu -> Setup -> Sensor Setup) by choosing 'FlyBox Autopilot + Sensors' and pressing 'Use'.

- FlightGear Flight Simulator: Receives simulated data from the Flight Gear Flight Simulator

- XPlane Flight Simulator: Receives simulated data from the XPlane Flight Simulator

- FlyBox Autopilot + Sensors: Receives attitude, position and sends procedure deviation information to/from the FlyBox Autopilot System

- GDL90 compatible device: Receives position, attitude, traffic and weather data from a GDL90 compatible device (such as Stratux, Golze ADL200, Talos Aelus-Sense etc...).

In the Advanced Setup you can add multiple sources of sensor data and assign different sources to different types of sensor data. This is usually not required and recommended only to be used by experts.

Many external SensorBoxes provide ADS-B traffic data. ADS-B traffic altitude is unfortunately encoded as "Pressure Altitude". To correctly calculate the altitude difference the actual static pressure must be known. This may result in wrong indications in case you use a pressurized cabin without measurements from the pitot static system. In this case it is necessary to provide the correct altimeter setting even if it is not used to indicate altitude.
