<p><br /> Flight restrictions have been lifted at all UK airports as the volcanic ash cloud has drifted away from British airspace.<br /> </p><p><br /> New measures that will minimise future disruption to flights caused by volcanic ash clouds are being introduced, according to the Civil Aviation Authority (CAA).<br /> </p><p><br /> The CAA said a Time Limited Zone had been agreed, in which it will be safe to allow flights for a limited time at higher ash densities than are currently allowed.<br /> </p><p><br /> To operate in the new zone, airlines need to present the CAA with a safety case that includes the agreement of their aircraft and engine manufacturers.<br /> </p><p><br /> UK airline Flybe is the first to achieve this and will be able to use the new zone.<br /> </p><p><br /> The CAA said this meant that areas of UK airspace that would have previously been closed can safely open, further minimising flight disruption.<br /> </p><p><br /> CAA chief executive Andrew Haines said: "I'm pleased that the huge efforts we're all making across aviation to keep flying safe, while minimising the disruption from the volcano, have resulted in further progress."<br /> </p>
