Statement on Icelandic volcanic eruption: Tuesday April 20, 1500 The situation regarding the volcanic eruption in Iceland remains dynamic and the latest information from the Met Office shows that the situation will continue to be variable. Based on the latest Met Office information, part of Scottish and Northern Irish airspace including Aberdeen, Inverness and Edinburgh airports will continue to be available from 1900 today to 0100 tomorrow, Wednesday 21 April, and also south to Newcastle Airport. Glasgow and Teesside airports will additionally become available in this time period. Restrictions will remain in place over the rest of UK airspace below 20,000ft. Flights above the ash cloud are now permitted in the UK; between 1900 today and 0100 tomorrow, this will enable aircraft movements above 20,000ft in UK airspace. We will continue to monitor Met Office information and the situation is likely to change during the course of the day. We will make a further statement at approximately 2100 today. NATS is maintaining close dialogue with the Met Office and with the UK's safety regulator, the CAA, in respect of the international civil aviation policy we follow in applying restrictions to use of airspace. We are working closely with Government, airports and airlines, and airframe and aero engine manufacturers to get a better understanding of the effects of the ash cloud and to seek solutions.
