| 2000 || {{w|Mobile phones on aircraft}} || A study by the [[w:Civil Aviation Authority (United Kingdom)|British Civil Aviation Authority]] finds that a mobile phone, when used near the cockpit or other avionics equipment location, will exceed safety levels for older equipment (compliant with 1984 standards). Such equipment is still in use, even in new aircraft. Therefore, the report concludes, the current policy, which restricts the use of mobile phones on all aircraft while the engines are running, should remain in force.<ref>{{cite web |title=Interference Levels In Aircraft at Radio Frequencies used by Portable Telephones |website=web.archive.org |accessdate=19 October 2019 |url=https://web.archive.org/web/20070616083454/http://www.caa.co.uk/docs/389/srg_acp_00021-01-030303.pdf}}</ref> || {{w|United Kingdom}}
