Cell phones linked to flight interference Friday, June 1, 2001 ASSOCIATED PRESS in Wellington Mobile phones have been blamed for at least two incidents in which aircraft made sudden uncontrolled movements mid-flight, the Civil Aviation Authority reported on Friday. Both incidents were examples of possible electronic interference with aircraft electronic systems, the authority said in its latest newsletter. CAA News said tests in Britain had shown signals from mobile telephones inside aircraft could reflect from metallic structures, making them strong enough to exceed trigger levels for critical airplane systems. The authority said an aircraft preparing to land at Wellington airport last Christmas Eve unexpectedly turned right and climbed while approaching the airport. A passenger's mobile phone is believed to have been the cause. The uncontrolled movement came at 1,400 feet (420 metres) during a landing approach using the aircraft's instruments. The crew quickly corrected the aircraft. No fault was found with the plane and two following aircraft reported no problems with the instrument landing system. The possibility of ground interference was rejected. In another incident, an aircraft cruising on autopilot suddenly rolled 30 degrees after a mobile phone rang in a bag in the cockpit. The CAA did not release the name of the airlines or the type of aircraft involved. Mobile phone use on planes is banned in New Zealand and punishable with a fine of up to NZ$1,250 (US$525) for an individual and NZ$7,500 (US$3,100) for a company. Laws governing the use of electronic devices on aircraft are to be tightened later this year in response to growing fears about their effects on aircraft systems. technology.scmp.com
