Knowledge base.

Which LX line fits which aircraft and which budget — what each one is for, what it costs you in panel work, and the questions that actually decide it.

One account for flights, files, instruments, orders and repairs — how to set it up and what lives inside.

What to update and how often, WiFi versus SD card, what to verify after every update, and a ten-point workshop check before the first good day of the year.

Where to find your order status and shipment tracking numbers — no account needed.

Where to find firmware, manuals and databases for your instrument, and how to hear about new releases.

Netto, relative, MacCready, QNH, ENL, total energy, dead band, AIRAC — every term an LX instrument puts on its screen, defined in a sentence and linked to the article that explains it properly.

Compatibility in tables: which navigation head, traffic receiver, display, recorder, radio, transponder and tablet combine with which, on the CAN bus and on the NAVIA network — and what does not interoperate.

Hub, Core, Sense, Displays, Traffic, UPS, EMU and Grip — what each unit does, how power and data flow over one cable per device, and how to plan a system before ordering.

The free online NAVIA at glider.flynavia.com: what it is, what Guest and signing in with your LX Cloud account each give you, how tasks and layouts built on the ground reach the aircraft, and what a browser cannot show you.

The thirteen steps from wired hardware to a configured aircraft: registering the Core to your account, aircraft identity and configurations, the polar, flight envelope and flaps, weight and balance, and the checks before the first flight.

Personal accounts that follow you to any NAVIA aircraft, the four roles and how ownership is established in LX Cloud, pilot in command, screen and login types, display profiles, and adding a phone or tablet as an extra screen.

What belongs to you and what belongs to the aircraft, when synchronisation runs and why it never runs in flight, flying with no internet at all, and how a recorded flight reaches the logbook and the cloud.

The update page and its three channels, reverting a version, why connected devices update themselves from the Core, keeping airspace and charts current, and the remote-support switch that stays off until you turn it on.

What each status-bar item reports, the full list of warnings and alarms with what triggers them, and a symptom-cause-fix table for the sixteen things most likely to puzzle you — several of which are not faults.

The thermocouple rules that govern everything, where CHT and EGT probes go and where they must not, RTD and pressure senders, fuel quantity and flow, RPM pickups, and two worked engine examples.

How the annunciators behave and what acknowledging one does, what a missing reading means in flight, the fuel computer and its limits, calibrating a tank point by point, and why the factory thresholds are not your engine limits.

The integrated IGC recorder and its security seal, engine noise and when an external means-of-propulsion sensor is required, the Certificate of Calibration that replaced the barochart, and a compass that calibrates itself in flight.

Two modules updated separately, why obstacle databases and licence files are tied to your serial number, configuring the unit from its portal, connecting it to a Core Pro, and reading the range analyser honestly.

Sending flights over WiFi, putting the instrument into Bluetooth server mode, pairing an Oudie or an Android phone, the NMEA sentences and baud rate to set, the wired user port, and configuring iris over CAN2WiFi.

What it means for a navigation display to control a radio, which radios are documented on which platform, wiring and menu setup, the audio and push-to-talk job that is separate from the data link, and what is documented about transponders.

Where the protocol runs, sentence anatomy and the checksum rule, the broadcast and request-response families with their command groups, a worked exchange, task declaration, and the NAVIA open platform for anyone building their own.

Open a repair ticket, ship the device, follow the process — what happens at each step and how long it takes.

What is in the box, how the Era is installed and wired, what to configure before the first flight, and the settings pilots most often get wrong.

Choosing the right iris, mounting it so the attitude is accurate, pitot and static, alignment, the calibrations that belong to the aircraft, and a troubleshooting table.

What carries over from the old system, what is new behind the panel, how to choose the vario indicator, what data to bring across, and the first-flight checks.

Termination, topology, where to feed the power, cable and connector practice — the five installation mistakes behind almost every intermittent panel fault.

Declaring a task before flight, the five ways a task reaches the recorder, what the declaration carries besides turnpoints, the logger settings that matter, and the three routes for getting the IGC file off the instrument.

Power, the two FLARM ports, antenna placement that decides your range, which licences unlock which functions, and how to verify your installation from recorded contacts rather than from the ground.

The LED ring colour by colour, the start-up sequence, the idle and warning screens, the fault indications and the audio warnings — plus which cable your FLARM needs.

Two instruments that share their software: the gestures and knobs that drive them, the pages they show, the databases they need, the settings worth doing once, and how to update them.

What the red warning square means for each of the ten switchable warnings, what triggers it, what to do about it — and the warnings that are really settings, including the silent vario and the airspace alert that never comes.

This document describes FLARM Eagle WiFi update procedure.

All Iris devices contain internal backup battery that enables the device to run uninterruptible in case of the main power supply malfunction.

What still exists for instruments out of production: repair while parts last, IGC recalibration and resealing, download-centre pages per device, getting your data off before retirement, and the natural upgrade for each family.
