BOAC,
any idea why the significant difference between Jepp normal and JAA RVRs on ILS 06?
We're talking about the state imposed minimas here. from Italian AIP
Aircraft special procedures in low visibility conditions
1) All flight operations forbidden with RVR less than 700 m due to 615 m reduced approach lighting system
2) Due to unavailability of stop bars, ACFT movements on manoeuvring area restricted to one at a time with RVR less than 550 m
3) Landing for RWY 06 is allowed as follows: a) Visibility/RVR 900 m or above with ILS approach
b) In other cases: visibility 5 Km or above and ceiling 2000 ft or above during HJ -/+ 30; visibility 8 Km or above and ceiling 2000 ft or above during HN
The reasons behind might be the glide slope of 3,5 and the LOC offset of 3 degrees not to mention displaced THR thus logically higher RVR/VIS.
