Frequently asked questions

Drop one IGC file into Flight analysis or click the upload area to browse. Aircraft, mass and polar details are optional. Start the analysis, then open the report from the completed preview.

A chart needs suitable recorded data. Missing fixes, an unknown altitude reference or too few consistent circles can prevent a reliable result. A straight climb can be wave or ridge lift; it is not automatically a thermal. Report a suspected error through Contact with its reference and timestamp.

The recorder supplies GNSS and pressure altitude as separate channels. Terrain comes from Mapterhorn beneath the selected track. AGL is their height difference only when the references are compatible; an estimate or uncertainty must remain identified. Pressure altitude is not automatically height above sea level.

No. A suitable polar and the flight mass improve model-based airspeed and performance calculations. These are estimates, not a replacement for measured airspeed. The polar page identifies available source and model information.

The buttons are currently placeholders. Cloud import is not connected yet; download your IGC and upload it from your device.

Compact shows what happened in the flight. Full adds detailed explanations and coaching, including advanced thermal, wind and performance analysis where the data support it. Free uploads receive Compact; Full requires the applicable access or coupon. Locked areas show what is available in Full.

No. They use saved, prepared reports without processing an IGC again. The progress display is a demonstration. After it finishes, you choose when to open the report. The latest nine shared flights are kept in the active library; three are presented as Compact examples.

Charts with these controls open in a framed window and offer the formats shown in their download menu. Image exports include branding and a legend where relevant. Chart CSV export is available in Full. Your browser session is not a permanent archive: save the reports you need.

The upload can supply thermal measurements independently of the optional public-flight sharing consent. A file hash prevents duplicate ingestion. Pilot names, aircraft and recorder identifiers are not included in the thermal processing data. Opening a saved example does not ingest it again.

Live thermals use today’s OGN observations in the area around the map, within a 200 km-wide generation zone. Choose the last 30 minutes or the last 60 minutes. The daily thermal collection continues separately. Coverage and delay depend on reception and available data.

They support review and preparation, not operational navigation. Terrain, airspace, traffic and weather can be incomplete or delayed. Check official sources. The optional rain radar shows the available data from the last 60 minutes only when the map scale is below 50 km. Data are requested only in this view, using a server cache refreshed every ten minutes.

No. Sharing with Latest flights and website illustrations requires a separate, initially unchecked permission for each upload. Declining does not prevent analysis. Shared assets omit names and aircraft identifiers, but a route and its times can still be recognisable. The original IGC is not offered for public download.

Contact us with the flight reference or identifying time and area, or with your account email for an account request. Never send passwords. Removing a private report does not itself remove a separately shared asset. We can remove our publication, but cannot recall copies already saved by others.

Coupon issue and redemption are recorded. The reply indicates whether the earlier coupon is still usable or was already redeemed, with the recorded date. Requesting a coupon or creating an account does not start a paid subscription.
