The 3D view is not a stored model of the world — it streams it. The photoreal ground, the terrain and the satellite cloud imagery are fetched tile by tile as you fly, from Google, Cesium and NASA. A whole-world copy would be hundreds of gigabytes, so it cannot ship inside the app.

What BELT can do is prepare before you lose signal. Open the flight while you still have Wi-Fi at the gate and BELT saves a cloud snapshot and a rendered map of your route; in airplane mode the view then replays those saved clouds and draws your flight over them, and tells you how old the snapshot is. Airline Wi-Fi, where you have it, brings the full view back.

Because free public radar mosaics are a US thing. BELT's radar layer comes from NOAA and aviationweather.gov, which cover the United States and nothing else. There is no equivalent open feed for most of the world.

Outside US coverage BELT does not go blind — it switches to sources that are global: geostationary satellite cloud imagery from NASA GIBS (GOES and Himawari), model cloud and wind fields from Open-Meteo, and BELT's own worldwide turbulence engine. The ride forecast works on any route. You simply will not see a radar sweep over, say, the Atlantic.

One gap worth knowing: GIBS has no geostationary layer over Europe, Africa and the Indian Ocean yet, so the satellite cloud picture thins out there and BELT falls back to the model clouds.

Open Settings › Privacy in BELT. There are two separate switches:

• Share bump reports — on for new installs. It sends one coarse point per bump (where it started, how strong, how long, the flight number), and nothing at all for the smooth minutes in between. This is what draws the crowd ride layer other flyers see.
• Share full ride log — off unless you turn it on. This one is the whole session file, including a continuous GPS track of the flight, used only to calibrate turbulence sensing.

Switch either off and anything still queued to upload is discarded with it. A copy of your own ride log always stays on the phone either way, and you can export it yourself from the RIDE SENSOR card.

Try these in order:

• Check the airline code and the date. Use the operating carrier's number, not the codeshare you booked under — a flight sold as AS 1234 may operate as QX 1234. And check the departure date in the airport's local time, not yours.
• Try again closer to departure. Schedule sources thin out for dates more than a few days ahead and fill in as the day approaches. Within about 24 hours of departure almost everything resolves.
• Search the route instead. Enter the two airports and pick your flight from the day's list.
• Very small operators, charters and cargo sometimes never appear — the public feeds simply do not carry them.

If a normal scheduled flight is still missing, email us the flight number and date and we will look at the feed.

No — that is deliberate. Captain BELT is meant to sound like the announcement you would actually hear from the flight deck, so the audio is band-limited and lightly compressed the way a real intercom is, pauses where a captain would pause, and opens with the PA click. It is an AI voice reading a briefing generated from your flight's real data; there is no person on the other end and it has nothing to do with your actual crew.

If you would rather read than listen, the same briefing is on screen as text, and the captain voice can be switched off in the briefing panel.

A Wi-Fi-only iPad has no GPS chip, and iPadOS will not forward an iPhone's location to it in airplane mode. GPS Link is BELT's own bridge — peer to peer, no internet, no hotspot, no shared network.

• Install BELT on both devices and open it on both.
• On each device go to LAYERS › GPS Link and turn it on. Allow local network and Bluetooth when iOS asks.
• The first time they meet, both screens show the same six-digit code, and the iPhone — the device whose GPS would leave — offers Allow. Check the two codes match, then tap Allow.
• That is the only time you do it. From then on the two link silently whenever both have BELT open, like AirPods. GPS Link turns green on the iPad.
• Adding a third device later: tap Pair a new device on a device that is already paired, which opens a two-minute window, then approve the code on the phone. Forget paired wipes the list.

Keep BELT in the foreground on the iPhone during the link — iOS suspends peer-to-peer sessions in the background. Only devices you have paired can send or receive a fix.

Settings › Privacy › Delete my uploaded data, then confirm. That removes every bump report and ride log stored for your phone on BELT's server, plus anything still waiting to upload. Your sharing switches are left as you set them, so turn them off too if that is what you want.

There is no account to close — BELT never had your name or your email, only a random identifier created on the phone. Deleting the app removes everything held locally. Full detail is in the Privacy Policy.
