On 2 April 2015 the UK will complete the move from quadrantal to semi circular cruising levels. This change affects pilots flying under instrument flight rules outside controlled airspace below flight level195, but higher than 3,000ft above mean sea level, as semicircular cruising levels have been used in controlled airspace for many years. The timescale for this change has been extended to allow a safe transition to the new arrangements.
CAA Head of Intelligence, Strategy and Policy, Padhraic Kelleher, said: “We welcome the very pragmatic approach that EASA and the Commission have taken. This means that as we draw the UK’s implementation of SERA to a close the UK’s position and the needs of our airspace users have been fully taken into account.”
