MVario2 is a system that measures atmospheric pressure and using the obtained data it calculates the altitude above sea level, airspeed, and the rate of climb as well as the rate of descent. Changes in climb and descent rates are signaled as well. The sensor also alerts you if any alarm setting is exceeded.

The sensor enables an acoustic signal for the climb rate/descent rate or for exceeding of a pre-adjusted limit value. The acoustic signal consists of 4 different kinds (steps) for climbing and the same amount of steps for descending. The step width can be adjusted by the user. The climb signal consists of short interrupted tones, the descent signal consists of long permanent tones.

The Duplex system takes advantage of the 2.4GHz band for communication. This system not only transmits control data to the model but also sends data from the model back to the transmitter. The telemetry data collected during operation is shown as actual, measured values in real time on either LCD screen of a connected JetiBox Profi or on the DC/DS line of Jeti transmitters.

For competition flights in FAI F5J category there exists a separate firmware that is freely available to be downloaded on www.jetimodel.com and is always marked with its version MVARIO2 V. FX.XX. This firmware has been made as simple as possible, the telemetry functions are blocked and is possible to be used only as an altitude limiter.
