Hi Autobrake
can you please state the Jeppesen page reference?
I took it not from the manual but from this Jeppesen briefing document (see p.23):
http://www.theairlinepilots.com/foru...psjeppesen.pdf
However to me that seems to be largely an amplification of your reference from the manual. On page Approach-10 in the manual, the
Guide for Visibility Label Usage indicates that the labels V and VIS (similarly R and RVR) are equivalent - in my experience the labels VIS and RVR are generally used, notwithstanding the wording you quote from page 9.
On page 10 we also see:
Only visibilities that have been supplied by the State Authority will be labeled with a "V".
....feeding my speculation in the Bangalore case (with apologies for this serious thread drift) that Jepp are quoting the VIS (800) as published by the State, but are recalculating the RVR upwards from the usual 550 for some reason (a more accurate derivation per PANS OPS criteria, perhaps?) also knowing that this more conservative RVR will trump the published VIS for their customers.
It would be nice to get some clarification on the question from Jeppesen themselves.
