§ Mr. BrakeTo ask the Secretary of State for the Environment, Transport and the Regions, pursuant to the answer of 21 January 1998,Official Report, column 549, on air misses, how many air misses took place in the United Kingdom in each of the last 10 years in categories (i) A (real risk of collision), (ii) B (possible risk of collision) and (iii) C (slight risk of collision). [30418]
§ Ms Glenda JacksonThe Civil Aviation Authority (CAA) has supplied the following breakdown of Air Proximity (Airprox) incidents in UK airspace in each of the last 10 years for which figures are available. The figures include both civil and military incidents. The totals differ from those provided in theOfficial Report, 21 January 1998, column 549, because the latter, which were taken from the CAA Annual Report and Accounts 1996–97 page 71, excluded military incidents. The definitions of categories have been adjusted to reflect the formal definitions used in Airprox reports. I have arranged for a copy of Aircraft Proximity Reports (Airprox C) Volume Twelve to be placed in the Library.
