Airborne use of GPS Watches
Apologies, I can't think of another thread on which to ask this question. I have bought a Seiko Ariston watch whose timekeeping is controlled and adjusted by the reception of time signals from GPS satellites. The watch instructions provide for the turning off of the reception mode, in an aircraft 'where the reception may influence the operation of other electronic devices in an aircraft.' Is this really a consideration? I find it hard to believe that a small GPS receiver could cause a problem, particularly as some airlines are considering allowing the use of mobile phones on board. Should I be turning this function off in flight?
