If you fly Airbuses as I do, when you do your LPC/OPC under the new EASA scheme of life, your licence will now have a renewal/revalidation saying A320 SERIES IR/LV. That is just to state formally that your low viz qualification has been tested and revalidated for another year. In the past it was not stated even though it was true - now it is formally written down to show to any Inspector that you are authorised to carry out Low Viz Operations.
