May 4: With a change in the direction of the wind, the volcanic ash cloud from the eruption in the Eyjafjallajoekull area of Iceland has moved back toward the UK, resulting in the closure of airspace over Ireland.
UK air traffic services provider NATS says that it expects all UK airspace (including Northern Ireland) to be open this afternoon from 1300 (local time), with the exception of a very small no-fly zone identified by the Civil Aviation Authority (CAA) in the northwest corner of UK airspace, but is not expected to have any impact on UK operations. All traffic above 21,000ft is unaffected.
May 5: NATS says that the no-fly zone imposed by the CAA will extend from 1300 (local) today to include Belfast City, Belfast International, Ronaldsway (Isle of Man) and Edinburgh Airports. All other airfields currently within the no-fly zone remain within it.
The no-fly zone imposed by the Civil Aviation Authority continues to move further south and west in line with the high density area of the volcanic ash cloud. According to latest information from the Met Office, Edinburgh Airport will come out of the no-fly zone and become available for operations from 1900 (local). All other airfields currently within the no-fly zone remain within it from 1900 to 0100 tomorrow (Thursday). During this period the no-fly zone extends over most of Ireland and clips the west coast of northern England and Wales; however, most of Wales, England and eastern Scotland are now outside the high density area.
The Met Office advice suggests that the cloud will continue to move south-westerly overnight and it is hoped that fewer restrictions will be necessary tomorrow (Thursday).
