The wind measuring instruments must be placed alongside the landing slope at the height of the optimal flight trajectory. The measurement data for these devices must be available to competition officials in the judges’ tower.

Measuring instruments must be placed in three locations on normal, large and Ski Flying hills (at the edge of the takeoff as well as at approximately 50% and approximately 100% of the distance to the K-Point).

In addition, at least 8 wind flags or wind socks must be placed along each side of the landing hill at the height of the flight trajectory.
