WXStar - Starlink Service Plans
Bottom line: WXStar works with the cheapest Starlink plan available — the Standby plan at around 10 EUR/month.
⚠ Two separate subscriptions required: In addition to your Starlink plan, you also need a WXStar Data Service subscription at 290 EUR + VAT per year (paid to us). ADL customers with an active service plan get the WXStar data service included at no extra charge — the hardware must still be purchased separately.
WXStar uses very little data - weather products are compact by nature, and a 500 kbps connection is more than sufficient to receive everything in real time. This means you almost certainly do not need one of the expensive aviation plans.
Starlink's Standby mode (also known as Basic Connectivity) is the recommended plan for WXStar. Travel and Roam plans also work well. The full aviation plans are only worth considering if you also need in-cabin internet for passengers.
WXStar includes built-in Starlink connection management that keeps your weather data
flowing automatically - no user interaction required.
As a result, any Starlink plan that is not locked to a fixed location works
with WXStar, including Basic Connectivity (Standby) at just ~10 EUR/month and
Travel/Roam plans.
The only exception is ocean coverage: if you fly beyond 12 nautical miles offshore and
need weather data there, you will need a plan with ocean coverage (Aviation 450 MPH or
a Jet plan).
If you use a Standby or Travel plan and want to feed an EFB app (ForeFlight, SkyDemon, Garmin Pilot), see EFB Apps via WiFi for how the WXStar iOS app ensures an uninterrupted GDL90 stream.
The table below reflects our best understanding as of May 2026; prices include VAT and vary by country. Plan names and prices change frequently — always verify on starlink.com before purchasing.
| Plan | Monthly Cost (incl. VAT) | Ocean Coverage | Good for WXStar? |
|---|---|---|---|
| Standby (also called Basic Connectivity) |
~10 EUR | No | Yes - recommended |
| Travel / Roam - 100 GB | about $40 | No | Yes |
| Local Priority - 50 GB | about $65 | No | Yes, but offers little advantage over Travel plan for WXStar |
| Aviation 300 MPH | $250 | No | Yes, but overkill for weather only |
| Aviation 450 MPH | $1,000 | Yes | Yes - needed for ocean use |
| Aviation Jet 20GB / Unlimited | from $2,000 / contact Starlink | Yes | Yes - needed for ocean use |
These are two separate subscriptions paid to two different parties:
| WXStar Data Service (us) | Starlink Internet (SpaceX) | |
|---|---|---|
| What | European weather data for your avionics | Satellite internet connection |
| Price | 290 EUR + VAT / year Free for ADL customers with any active service plan! |
Standby ~10 EUR/mo (or aviation plans from ~$250/mo) Starlink prices change frequently — check starlink.com for current rates. |
