Interpretation
AIP text for EPWA has been changed: low-visibility procedures (LVP) will commence when the touchdown zone RVR on the arrival runway falls below 800 m and/or any RVR falls below 550 m and/or the cloud ceiling falls to or below 300 ft. LVP will be terminated when the touchdown zone RVR on the arrival runway increases to 800 m or more and/or all RVR increase to 550 m or more and the cloud ceiling reaches 300 ft or more and a continuing improvement is anticipated. This replaces the previous criteria that commenced LVP when any RVR fell below 550 m and/or the cloud ceiling fell below 200 ft, and terminated when all RVR increased over 550 m and the cloud ceiling reached 200 ft or more with continuing improvement anticipated.
