The METAR arrives _after_ /sim/signals/nasal-dir- initialized is fired which triggers the runway selection code in startup.nas. This code uses the raw, not interpolated wind values from the metar, so it's definitely not an interpolation issue.

This needs some thinking about when interpolation is required and when it should be avoided. The scenarios to think about are: - System startup - System reset - Transition from manual input to real-weather - Transition from real-weather to manual input - Change in manual-input data - Teleporting to another position - to be continued And for each scenario probably distinguish between in-air and on-ground. Any suggestion how to handle these is appreciated. Torsten ------------------------------------------------------------------------------ Beautiful is writing same markup.
