Discrepancies in Aircraft Runway Visible Range (RVR)
A Category I ILS has visibility minimums that canít go below 1/2 mile. So, it gets confusing when Jeppesen equates an 1800 RVR requirement to only needing 3/8 mile visibility.
If your aircraft's instrument landing system cannot go below half a mile, you will find trouble with Jeppesen charts, which measure runway visible range by one-eighth of a mile increments.
