Thanks for that link, no sig. Very important research.
Here's a small excerpt from the Executive Summary, which I will probably carry in my kitbag (to show to anyone who thinks the cell phone ban is unjustified) :
- Compass froze or overshot actual magnetic bearing.
- Instability of indicators.
- Digital VOR navigation bearing display errors up to 5 degrees.
- VOR navigation To/From indicator reversal.
- VOR and ILS course deviation indicator errors with and without a failure flag.
- Reduced sensitivity of the ILS Localiser receiver.
- Background noise on audio outputs.
In the "Background" section, there was also a list of actual events which were reported and which prompted the research. These were:
- Distraction of the flight crew from their normal duties;
- Interrupted communications due to noise in the flight crew headphones;
- Increased work load for the flight crew and the possibility of invoking emergency drills;
- Reduced crew confidence in protection systems which may then be ignored during a genuine warning;
- Malfunctioning of multiple systems essential to safe flight.
