A guy i spoke to recently has a garmin III Pilot Handheld GPS that he takes and uses onboard when he's a passenger.we were debating whether this is allowed by airlines and if indeed it is safe as far as the aircraft's avionics,nav and radio equipment is concerned.it certainly doesn't interfere up front with anything up to a Kingair-sized a/c.
i'd be very interested to find out if the use of such an instrument in the cabin is permitted or not,and if not,why not?
It certainly sounds like a nifty bit of fun to track your flight as you fly from your seat,but is it safe,and if not,then why?
