It is true that most of the evidence about RMI from personal electronic devices (PED) carried on board is anecdotal, but most originates from flight crews who were able to eliminate random perturbations in navigation and communitions equipment by having a passenger turn off the offendiong device...The RTCA has special committee work on the subject and fairly extensive testing has been done...not all conclusive, but not yet (IMHO) able to dispell the "myth". And as for immunity of modern avionics and flight management and control systems to "high-powered radio transmitters"...does anyone remember reports of military aircraft (fly-by-wire) flight control problems occurring in the vicinity of the Radio Free Europe transmitter/antenna in Germany in the early eighties???? Better safe than scoff.....? ______________________________ Reply Separator _________________________________ Subject: Re: Can't use GPS on Alaska Airlines Author: firstname.lastname@example.org at smtpgate Date: 9/3/96 1:16 AM Robert Moore wrote: >(snip) > One of the worst airline midair accidents was caused by a passenger playing > his portable FM receiver during flight. (snip) Please identify the accident and the circumstances. It seems incomprehensible that aircraft avionics that MUST frequently fly over high-powered radio transmitters could be so suceptible to stray onboard RF. My understanding is that the restrictions on in-flight use of electronic devices is based entirely on unsubstantiated anecdotal evidence.
