Convek
For instruments

Soaring forecast data for flight computers.

Instruments and companion apps need compact, predictable forecast data. Convek exposes thermal strength, usable height, cloudbase, wind, convergence, and route samples through stable JSON endpoints.

Pre-flight sync

Download a small set of site or route forecasts before launch.

Route context

Show expected lift, height, and wind changes along a planned line.

Offline summaries

Cache JSON responses in a companion app or device workflow before the pilot leaves coverage.

Example API call

Route sample using a bearer API key.

Where it fits

Forecast layer

Convek

Use for thermal strength, cloudbase, usable height, convergence, soundings, grid slices, and route samples.

openAIP

Use for airspace, airports, navaids, obstacles, and flying-site records.

OGN

Use for live traffic, tracking, and replay where receiver coverage exists.

Open-Meteo

Use for generic rain, temperature, pressure, and fallback weather outside Convek regions.

Build against real soaring fields.
