RE: Cell phones ?
In the UK the regulatory body for most clubs shows reccomends that no cell phones be operated on or near the flight line or pits.
I was part of an ad hoc group who tried to show that this was not a problem and we did not find any evidence that it could happen during our experiments. However there is a body of evidence that shows that if you are operating with the aerial retracted, say in the pits, and a cell phone rings within a few feet it can and does cause a major glitch on some rare occaisions. I have personally witnessed such a glitch. Of course it could be something else but the timing was suspicious.
SYNTHESISED TRANSMITTERS AND MOBILE TELEPHONES
Following the crash of an expensive gas turbine model helicopter, the investigation into the cause revealed that the synthesised transmitter being used to control the helicopter was interfered with by a nearby mobile telephone. In this case it was a Multiplex transmitter but it is possible the same could occur with other synthesised transmitters.
The transmitter manufacturer’s instructions were scrutinised and found to contain a warning that mobile telephones were not to be used within the direct vicinity of the transmitter and subsequent trials revealed that the incident was repeatable with that transmitter. The UKRCC will be carrying out further investigations to determine the extent of the problem and will be advising in the future.
The BMFA already recommends that mobile telephones are not taken into the pits or flying area for other reasons but be aware that mobile telephones could interfere with synthesised transmitters.
