Visibility is how far prominent objects can be seen. For VFR in Europe, SERA.5001 generally requires 8 km at and above FL100 and 5 km below FL100 in airspace classes C to G.
- German term
- Flugsicht
Lower minima can apply close to the ground in class F and G airspace, subject to national rules and conditions such as clear of cloud and in sight of the surface. METARs report ground visibility, which is not always the same as flight visibility.
In practice
Haze against the sun can feel far worse than the reported value — plan a margin above the legal minimum.
