The 32L ILS at Launy has a shaded S-I minima box so it may be reduced by 100ft when an accurate QNH is available (ATIS, AWIS outside tower hours). It also has an additional note that the visibility may be reduced to 0.8km (cat I minima other requirements met also) from 1.2km if an actual QNH is obtained.
QNH from TAF DA is 850(302) and 1.2km vis
QNH from approved source DA is 750(202) and 0.8km vis
This all assumes you and your aircraft can use these minima.
For instance are the HIALS activated with the AFRU+PAL after hours?
I am interested whether this is a Jeppesen term or CASA. AIP/DAP don't mention conditional DA/MDA and I don't have a set of Jepps at hand.
