GRAUPNER G-BOOSTER 160 – Manual 1.91
Airspeed Sensor
The JETRONIC-Vx allows the connection of an optional airspeed sensor to the AUXiliary con-
nector. For the measurement, a pitot tube (Prandtl type) and an electronic pressure sensor are
used. The tube is mounted on the outside of the model in flight direction and the sensor is mounted
inside the model. The two components are connected via the two included pieces of tubing.
The measurement of the airspeed in flight allows several useful functions:
●
Determining the (maximum) airspeed [km/h] (see INFO:15 AIRSPEED-PEAK)
●
Determining the covered total distance [km] (see INFO:16 AIR-DISTANCE)
●
Limiting the airspeed to a value allowed for the aircraft model
(see LIMITS:37 AIRSPEED-MAX)
Connection
In order to achieve a precise airspeed measurement, the pitot tube should measure the stagnation
pressure only on parts that are parallel to the incoming airflow.
●
Do not mount the tube on conical areas.
●
Keep a minimum distance of 2.5 cm (1") to a parallel surface.
For a more precise measurement, you can also mount two airspeed sensors, for example on the
wing tips, which are connected in parallel using a V-cable.
