Takeoff Temperature Improvements

Your manual temperature stays put#

Until now, a takeoff temperature you entered yourself could be silently overwritten the next time you opened the flight, whenever a fresh Meteoblue forecast had arrived. That is fixed.

• Not adjusted? The takeoff temperature keeps following the Meteoblue forecast automatically, exactly as before.
• Adjusted it yourself? Your value now sticks — through forecast refreshes, reopening the flight, and manifest downloads.

Switch back to Meteoblue with one click#

When a temperature is manually set, a small icon appears next to the takeoff temperature field. Click it to clear your manual value: the field returns to the Meteoblue temperature and follows the forecast again.

Pressing the Use Meteoblue button (or the forecast button on the lift card) also switches the temperature back to the forecast.

A more realistic forecast temperature#

The Meteoblue takeoff temperature previously used the average over the flight window, which often came out several degrees too cold — and made the lift calculation too optimistic on paper, too pessimistic in your head.

It now uses the highest temperature within the flight window — in practice the temperature around 2 hours after sunrise for morning flights, or 2 hours before sunset for evening flights. This is the reference the lift calculation works with.

Everywhere the same number#

The flight detail page, the calendar flight card, the manifest and the pilot sign-off screen all show the same takeoff temperature: your manual value when you set one, the improved forecast value otherwise.

No action needed — this applies automatically to all flights.
