They are the system doing exactly what somebody configured it to do — a Child screen politely waiting for its parent, an owner-only page hidden from a Regular account, a flight that has not reached the cloud because the aircraft has not seen internet since it landed.\n\nThis article is the reference for telling those apart from real ones: what each status-bar item reports, what every warning and alarm is triggered by, and a symptom-by-symptom table for the things that most often send pilots looking for a manual.\n\n## The status bar reports the system, not the flight\n\nThe status bar along the top of every screen is about the health of the installation: recorder state, power, connectivity, databases, pending updates and the devices on the network. A glance at it after power-on tells you the system is complete.\n\nThe important convention: **an item only demands attention when it is highlighted.** A status bar full of quiet icons is a healthy one, and there is no need to interpret each of them before every flight.\n\n## Status bar items\n\n| Item | Reports |\n|---|---|\n| Logger | Flight recorder state — ready, recording, or closing the flight after landing. |\n| Battery | Active power source, charge state and, on backup power, remaining time. |\n| Network | Internet connectivity: Wi-Fi, cellular signal, or none (offline mode). |\n| Communication | Health of each connected device: radio, transponder, traffic receiver, external sensors. |\n| Satellites | GNSS reception status. |\n| Maps | Map and chart services: databases loading or missing. |\n| Core update | A system software update is available or in progress. |\n| Ecosystem update | A connected NAVIA device — Sense, Grip and the rest — is receiving firmware. |\n| Inputs | State of the configured digital inputs: gear, airbrakes, event button. |\n\n## Warnings and alarms\n\nAll of these are enabled and tuned under `User Settings › Notifications`, and most produce both an on-screen alert and a voice or tone output.\n\n| Warning | Triggers | Applies to |\n|---|---|---|\n| Traffic | Conflicting traffic or obstacle reported by the traffic receiver | All |\n| Terrain | Predicted terrain conflict ahead, with advisory levels up to \"Pull up!\" | All |\n| Airspace | Approaching or entering airspace of an enabled class or type | All |\n| Stall | Airspeed near the configured stall speed | All |\n| VNE | Airspeed near or over the never-exceed speed | All |\n| Flaps max speed | Speed outside the current flap position's range | Aircraft with flaps |\n| G load | Load factor outside the configured limits | All |\n| Maximum \u002F selected altitude | Reaching the configured or selected altitude | All |\n| Gear (takeoff, landing, outlanding) | Gear state inconsistent with the flight phase, with the gear input wired | All |\n| Air brakes | Airbrakes out at the wrong moment, with the input wired | Glider |\n| Engine parameters | Any EMU channel leaves its configured zone | Motorplane |\n| C.G. out of limits | Current loading outside the C.G. envelope | All |\n| Battery low \u002F backup power | Supply voltage low, running on UPS, or main power restored | All |\n| Ballast dump temperature | OAT near the minimum for dumping water | Glider |\n| Oxygen | Above the configured oxygen altitude | All |\n| Drink \u002F sunset | Regular hydration reminder; sunset approaching | All |\n\nSeveral of these depend on numbers entered at commissioning — stall speeds, VNE, load factors, the C.G. envelope — and several depend on an input being wired, notably gear and airbrakes. A warning that never fires is worth investigating before you conclude that you never needed it.\n\n## Tuning notifications without disabling them\n\n`User Settings › Notifications` is personal, so it follows your account rather than the aircraft, and the tuning that suits your flying arrives with you in a club machine. Start by silencing the reminders that do not apply to your day — drink and sunset are the usual candidates — rather than the ones that watch the airframe.\n\n![NAVIA notification settings, where each warning is enabled and tuned](\u002Fsite\u002Fimg\u002Fkb\u002Fnavia-notifications.webp)\n\n> The warnings on that page can be switched off, including Terrain and Traffic. Turning one off to stop a nuisance alert is how a system that would have spoken up at the right moment ends up silent. Fix the cause instead — the airspace filter, the stall speed, the input wiring.\n\n## Symptom, cause and fix\n\n| Symptom | Likely cause | Fix |\n|---|---|---|\n| \"Aircraft not configured\" shown | Polar or envelope incomplete | Owner completes the configuration — see [commissioning a new aircraft](\u002Fkb\u002Farticle\u002Fnavia-commissioning-a-new-aircraft) |\n| Login page appears although `Remember me` was ticked | Auto-login is cleared when you log out, or the screen was reconfigured | Sign in once more with `Remember me` |\n| Second screen stuck waiting | It is a **Child** screen and nobody is signed in on its parent | Sign in on the parent display, or change the screen's Login Type |\n| Display Profile dropdown says *Unauthorised* | The screen currently belongs to another user | That user, or the owner, changes it — profiles are personal |\n| A widget shows a red cross | Its data source is absent: engine off, device missing | Check the device under `Instruments` and in the status bar |\n| No traffic on the map | Traffic receiver not configured, disabled, or ranked below another source | Owner: `Devices` page — device, `Enable traffic`, priority — then `Reconnect Serial Devices` |\n| Serial device silent after changing settings | New settings not applied to the port | Press `Reconnect Serial Devices` on the `Devices` page |\n| No warning sound | Notification disabled, or volume down | `User Settings › Notifications` and `User Settings › Audio` |\n| No vario sound *(glider)* | Vario audio disabled, or the silence band too wide | `User Settings › Audio › Variometer`; use `Play Sound` to test |\n| Settings did not follow me to another aircraft | Synchronisation had no internet window, and it never runs in flight | Give the system a few minutes online after sign-in, on both aircraft |\n| Flight not in the cloud | No internet since landing | `Logbook › flight › Sync to cloud now` once online |\n| Update refuses to start | No Wi-Fi internet, or signed in without owner\u002Fadmin rights | Connect the Core to Wi-Fi with internet; sign in as owner or admin |\n| `Airplane Settings` not visible | Signed in as Regular or Guest | Normal — only the owner and admins configure the aircraft |\n| Wrong time shown | Timezone or DST setting | `User Settings › Localisation` |\n| Phone cannot join the aircraft network | QR scan unsupported on the phone | Join the shown Wi-Fi manually, then open the NAVIA address in the browser |\n| Not sure which screen is which | — | `Identify` on the screen's card in `Screen Management` |\n\n## One symptom that is not a fault\n\n**Screens come alive one after another at power-up.** With several auto-login screens on board they sign themselves in one after another, so a display taking a few extra moments is normal. The two other non-faults in the table above — a missing `Airplane Settings` and a Child screen waiting for its parent — are the system working as designed.\n\n## Before you contact support\n\nHave these ready, and most cases are settled in one exchange:\n\n- What the **status bar** shows, and which item is highlighted.\n- Whether you are signed in as **owner, admin, Regular or Guest** — half of the \"missing\" pages are role-related.\n- The device list from `Instruments` (owner or admin), with **versions and serial numbers**.\n- Whether the aircraft has had an **internet window** since the symptom appeared.\n\nRemote access stays off unless you enable it, so if we ask for it during a case you turn it on then, and not before.\n\n## Where to go next\n\n- Background theory behind the warnings: [airspace](\u002Facademy\u002Fairspace), [how FLARM works](\u002Facademy\u002Fhow-flarm-works), [angle of attack](\u002Facademy\u002Fangle-of-attack) and [oxygen and
