LXNAV S8 / S80 Variometer
A Stand-Alone Digital Variometer, Final Glide Calculator
and Navigation System With Moving Map


General Description
LXNAV S8 (57mm) / S80 (80mm) is a standalone digital variometer, final glide calculator, and navigation system with a simple moving map. The LXNAVS8/S80 has both GPS/FLARM and PDA/PNA input/output. The unit has standard dimensions that will fit into a glider panel with an opening of 80 mm diameter (3.15″) or 57 mm diameter. It is also able to supply a PDA/PNA with power (5VDC/1A). The unit has an integrated high-precision digital pressure sensor and inertial system. The sensors are sampled more than 100 times per second. Real Time Data is displayed via a vario needle, an airspace map, and up to 4 variable numeric fields displayed on a QVGA 320x240 pixel, 3.5″ (S80) or 2.5″ (S8), high brightness (1200 nits) color display. To adjust values and settings, the LXNAV S8/S80 has two rotary push-button knobs and three additional push buttons.
The LXNAVS8/S80 can be expanded with one or more repeaters (LXNAV S8/S80) via the CAN bus. This allows both pilots in a two-seat glider to have independent control of all functions of each unit in the front or the rear seat.
Features
- An extremely bright 3.5’’ (S80) or 2.5” (S8) QVGA color display readable in all sunlight conditions with the ability to adjust the backlight.
- Two rotary switches (knobs) with push button function and three push buttons are
used for input. - Pre-loaded polar database for nearly all gliders.
- GPS/FLARM and PDA/PNA input/output.
- FLARM Indication if a FLARM is connected to the GPS/FLARM port.
- Programmable “needles” for selectable data such as netto vertical speed, relative (super netto) and vertical speed (vario).
- 320x240 pixels colour screen for additional information such as average, thermal vario, time, speed etc…
- Many custom audio settings.
- 100Hz sampling rate for very fast response.
- Speed to fly indication.
- TE compensation can be selected to be either pneumatic TE probe or electronic TE.
- Audio equalizer, for custom vario sound performance.
- Audio thermal assistant.
