LXNAV S20 digital variometer / flightcomputer 57mm.
The S20 combines a high-performance digital variometer, navigation, terrain, connectivity and flight assistance in a completely new 57 mm round display.
It fits into a 57mm size hole, which is a standard size on the instrument panel.
With built-in Wi-Fi, Bluetooth, LXNAV Connect, an advanced Thermal Assistant, a fully redesigned interface, an integrated IGC flight recorder and backup battery, the S20 brings a new level of performance, clarity and customization to the cockpit.

The S20 introduces a completely round high-resolution display, bringing a fresh and modern look to the cockpit while making essential flight information easier to read at a glance.
Also the edges of the housing are now rounded, feasing installations in tighter instrumentpanels.
Because of the completely round display, you can choose the screen orientation that works best for your cockpit — bottom, left or right.

The S20 comes with built-in GPS, Wi-Fi and Bluetooth for seamless wireless connectivity with your smartphone, Oudie and other cockpit devices.
Wi-Fi enables fast data exchange and automatic software and database updates — no SD card required.
The integrated IGC-approved flight recorder provides secure and reliable flight recording, with JET and electric engine detection available when a MOP module is connected.
PDAs or Smartphones can be connected to the system via internal Bluetooth or directly plugged to the PDA port. Flarm/PowerFlarm can be connected to a Flarm port.

The HAWK software (optional) enables you to see real time wind, an accurate netto vario and Artificial horizon.
HAWK applies an “extended Kalman filter� (EKF) algorithm that jointly estimates all three dimensions of the air mass movement.
No compensation needed, since it uses no law of energy conservation. More accurate netto vario readings independent of glider speed.
No false thermals due to wind gusts = No more “stick� lift.
The results of the attitude estimate of the EKF can also be displayed as an artificial horizon.

If an existing S8x/S10x harness is to be reused for the S20x, only care has to be taken to resolder the OAT sensor. Other than that all connections, including accesoiries, can be reused.
