4) Variometer operation

The Solar measures your vertical speed (climb or descent) and informs you in real time through an audible signal.

It uses a high-precision pressure sensor, combined with a 3-axis accelerometer and magnetometer. This combination of sensors improves the responsiveness and stability of the measurements, particularly during rapid trajectory changes or in turbulent conditions.

This technology allows the Solar to efficiently detect lift and provide reliable audio information, helping you optimize your positioning within air masses.

Audible signal

The Solar uses an audible signal to inform you of your vertical speed:

• a high-pitched sound indicates a climb,

• a continuous low-pitched sound indicates a descent,

• the absence of sound indicates stable air.

The frequency and rhythm of the audible signal increase with the climb rate, allowing intuitive and immediate interpretation.

Zeroing function (optional)

The Solar features a zeroing function, configurable via the Syride Link application. This function is disabled by default.

When enabled, the instrument emits a specific audible signal when your vertical speed is close to zero, that is between -0.2 m/s and +0.1 m/s.

This signal indicates that you are in a rising air mass even if you are not yet climbing, which may correspond to an area close to a thermal or the beginning of a thermal cycle.

This signal is only activated when the instrument detects a flight phase, in order to avoid any activation on the ground.

This function can help you more easily identify areas favorable for exploiting lift.

Recommended positioning

For optimal measurement, it is recommended to position the Solar in an area sheltered from relative wind, while remaining exposed to ambient air.

Recommended positions include:

• on a cockpit,

• on a harness shoulder strap,

• or in any stable area with low exposure to direct airflow.

Mounting on a helmet is not recommended, as head movements can cause airflow variations around the sensor and affect measurement accuracy.

Finally, do not place the instrument in a completely enclosed space, such as inside an airtight cocoon harness, in order to ensure correct ambient pressure measurement.
