Inspection and Troubleshooting
It is recommended to perform visual and functional inspections on a regular basis at least once a year. The PreLOG
is highly insensitive to external contamination. Nevertheless it should be ensured that no contaminations enter into
the interfaces or that they are not accessible due to severe icing. The inspection intervals have to be adjusted to
the respective environmental conditions.
