[quote]On the 29th April 2004, a Super Puma L2 (helicopter) was returning from offshore. As it was on the approach to it’s destination airport, a passenger used his mobile ‘phone. This resulted in the loss of all flight and navigation information on both pilot’s Integrated Flight Display System screens lasting one second during this critical phase of flight.
The UK Civil Aviation Authority carried out tests on two parked aircraft to find out the potential dangers of mobile ‘phone use. It found evidence that they produced interference levels which could disrupt aircraft systems. Faults attributed to mobile ‘phones include false cockpit warnings, malfunctioning of aircraft systems, interference in pilot’s headsets – all distracting the crew from their primary task.[Quote}
There was a CAA report issued following this investigation. When I get time, I will get the reference number, and post it.
