A forecast that's clear and smooth at eight thousand feet tells you nothing about the ridge you're crossing at four hundred. The weather that decides a rotorcraft day — mechanical turbulence, rotor off the lee slope, valley fog that burns off two hours later than the field — happens in a layer most aviation weather barely resolves.
METAR, TAF, winds aloft, radar and G-AIRMETs already ship in the app.
Route planning in the app is terrain-aware today — it knows the elevation profile along your route and already derives a turbulence estimate from terrain and wind. Weather isn't a new discipline for us so much as a deepening of something that's shipping.
Elevation along any route, at the resolution the planner uses now.
Forecasting a corridor is far more tractable than forecasting everywhere.
Every flight is a measurement. Actual wind and ride quality, at altitude, over time — the ground truth to check a model against.
Building the model is the cheap half. Aviation-grade weather — vendor radar, lightning, satellite, high-resolution model output — is commercially licensed and priced for companies with revenue. The free and open sources that make a prototype possible often carry terms that don't permit a commercial product.
So the beta is built on sources whose terms permit it, and the licence gets scoped before each next layer rather than after. That is the right order, and it is why some of what you would expect to see is not in it yet.
Radar, satellite, echo tops, turbulence down to a hundred feet, gridded flight category, icing and the GFA layers all run today — as a private beta, on our own machines. What stands between that and a link you can open is hosting: the low-level layers are rendered from model files by a tile server, and that has to run somewhere before anyone else can reach it. We would rather say that than put a button here that opens nothing. The weather in the app today — METAR, TAF, winds aloft, radar, G-AIRMETs, decoded and tied to each leg — ships now.
