Take care when in Italy.
They have recently amended their national procedures. An airfield in Italy can declare Cat II or Cat III Ops even if the RVR is above Cat I limits. You can not commence an approach unless you meet the declared Cat, even if the RVR is in your limits according to JAR or your own certification.
The details have not made the Jepps yet.
If you do an approach to JAR limits and the airfield declare a higher Cat then you get a free Quality audit on your returned flight paper work and aircraft check, but they don't sign it up in the quality manual for your quality manager!
