The C+ has a different type of detector to the older models so possibly the amp is also different. However, whatever component is affected, all that matters to the pilot is that the C+ "Smoke Det Baggage" caption can be spuriously triggered by a mobile phone. There is no fire extinguisher in the bay so it can be a serious issue. One theory is that it the phenomenon may have been missed during initial certification because UK phones are on a different freq. band to the USA ones.
By coincidence, my newspaper today tells of an airliner hurriedly diverted into a minor airport, from where it could not take off again, due to a spurious baggage bay warning. I believe they suspect BEES are the culprits in this case though!
