LXNAV S10 57 mm Vario, Navigation & IGC
The S10 is a standalone 57 mm digital variometer with navigation, final glide calculations and an IGC-approved flight recorder. GPS, Bluetooth and a backup battery are included. AHRS, HAWK, a Remote Stick and a second-seat repeater are optional.
LXNAV S10 – variometer, navigation and IGC flight recorder
The LXNAV S10 is a standalone digital variometer for a standard 57 mm panel cut-out. It combines a variometer, moving-map navigation, final glide calculations and an IGC-approved flight recorder.
GPS, Bluetooth and an internal backup battery are included in the basic instrument. The S10 can serve as the main instrument in a compact panel or as a backup alongside a larger navigation display.
Who is the LXNAV S10 for?
Glider panel upgrades
The 57 mm cut-out suits compact instrument panels. Check clearance behind the panel for the instrument, connectors and pressure tubing.
Cross-country and competition pilots
Vario information, task navigation and flight recording are available in one instrument.
Pilots using an external navigation device
The S10 offers its own navigation functions and can also connect to a compatible external device.
Variometer and navigation
Pressure sensors and an inertial platform provide the inputs for vario information. The digital needle, scale range, filtering and audio can be adjusted to suit the pilot.
Speed-to-fly and final glide calculations use the MacCready setting, glider polar, ballast and bugs setting. Correct entries are essential for useful results.
- Waypoint and task navigation
- Moving map, airspace display and warnings
- Thermal assistant showing the distribution of lift while circling
- Configurable navboxes and pilot profiles
- CUP waypoint and task files; CUB airspace files
Pneumatic and electronic TE compensation
Total energy compensation reduces the effect of airspeed changes on the vario indication. During a pull-up, airspeed is converted into height; a climb does not necessarily mean that the glider has entered a thermal.
Pneumatic compensation uses a TE probe. Electronic compensation uses the instrument’s pressure measurements. The S10 supports both methods, each requiring the appropriate pressure connections and settings described in the manual.
Changing a menu setting alone does not switch between the two methods. Electronic compensation requires suitable static and total pressure sources and verification in flight.
IGC flight recorder, Bluetooth and traffic display
The integrated IGC-approved flight recorder logs flights and supports task declaration. Flight files can be downloaded via a memory card or Bluetooth. An engine noise level sensor (ENL) is also built in.
GPS/FLARM and PDA ports provide wired connectivity; Bluetooth enables wireless communication with a compatible navigation device or app. The cable and communication settings depend on the connected device.
The S10 does not contain a FLARM receiver. Traffic radar and warnings require an external FLARM or PowerFLARM. ADS-B and other traffic information depend on the capabilities of that external device.
Optional AHRS and HAWK licences
AHRS enables an artificial horizon page using the instrument’s inertial sensors. It provides supplementary information in an instrument intended for VFR flying.
HAWK combines sensor data using an extended Kalman filter (EKF) to estimate air mass movement in three dimensions. It provides continuous horizontal wind and vertical air movement information, including in straight flight.
What does this mean for the pilot? Netto helps assess the strength of the rising air. This differs from the glider’s own climb rate, which also depends on its sink rate. On a glide, you may identify rising air even while the glider is descending slightly; while circling, the changing readings help assess which part of the circle has stronger lift and guide centring adjustments.
HAWK and the conventional TE vario can be displayed together. Interpret differences according to the selected vario, netto or relative mode. The two needles alone do not tell you whether to turn left or right: HAWK evaluates the air at the glider’s current location, rather than locating a distant thermal core.
HAWK does not use conventional TE compensation for its calculation, but still requires correct installation, inertial alignment and glider data. The S10 configuration offers AHRS or AHRS + HAWK as optional software licences.
Controls, backup battery and second seat
The 2.5" colour display features automatic brightness control. Two rotary push-button knobs and three push buttons operate the S10; a Remote Stick is not required.
The optional Remote Stick allows operation from the control stick. The S10 uses the CAN version for the S series. Select the diameter to match your glider’s stick; the necessary wiring is included with this accessory.
Radio and transponder connectivity requires an optional CAN Bridge and the appropriate wiring. Check the exact device model and version before selecting a connection; support does not automatically apply to every product from a brand.
A second seat can be equipped with an S10D or S100D repeater connected via CAN. The rear display size can differ from the front unit. The repeater is a separate optional accessory.
The backup battery provides up to three hours of operation according to the product specification. Endurance depends on brightness, settings and battery condition. It does not power an external FLARM, navigation device or Remote Stick.

Frequently asked questions
Useful information about the LXNAV S10.
Can the S10 work without another navigation device?
Yes. It has its own GPS, waypoint and task navigation, moving map and final glide calculations.
Do I need a Remote Stick for the S10?
No. The instrument can be operated fully from the panel. A remote control stick is optional; choose the S-series CAN version for the S10.
Does the S10 have built-in FLARM?
No. Traffic display and warnings require a compatible external FLARM or PowerFLARM and the appropriate connection.
Are AHRS and HAWK included in the basic price?
No. You can select AHRS or AHRS + HAWK in the configuration. These functions are activated by a software licence for the individual instrument.
Can the licences be activated later?
Yes. Before ordering a licence for an existing instrument, send us its serial number and software version. Activation does not require an additional AHRS hardware module.
Why can HAWK differ from a conventional vario?
The calculations use different principles and respond differently to changes in the air mass. Compare matching display modes: netto describes air movement, while vario also accounts for the glider’s sink rate.
Does the backup battery power other instruments?
No. It powers the S10 itself, not an external FLARM, navigation device or Remote Stick. The product specification states an endurance of up to three hours.
Can the S10 be used in a two-seat glider?
Yes. An S10D or S100D second-seat repeater can connect to the main unit via CAN. The rear unit and its connection are optional accessories.
