9. Visibility
Good racing can only be achieved if the birds can see where they are going. The visibility on the line of flight should be at least 10 kilometers. Poor visibility with low cloud obstructs the birds view of high buildings, church towers etc. Poor visibility can be caused by pollution, smog, dew, haze and any airbourne substance that blocks light. On the sites meantioned below the visibility on the line of flight is shown. The sites are regularly updated.
Excellent visibility
