Quote: MASH is quite right that you are suffering because most electronics have a microprocessor in them which has an oscilator and therefor potential to radiate and cause interference to navigation aids. My computer that I am typing on creates a huge interference on HF but it is not supposed to radiate. The lower powered devices like GPS have less radiation but then who is going to test and discriminate between all the devices a passenger might carry on board. Just like rules on dangerous cargo. Here in Oz the regulations do not speak to electronic devices only that you must do as the pilot says. The Authority leaves it to(and requires) the company to make appropriate regulations and enforce them. As there is of late a loosening of the regs about mobile phones I expect the rules on electronics to be loosened over time. (maybe). but yes all the electronics fitted to an aircraft are rigorously tested for interaction one with another. lastly I am surprised you could get a signal in the cabin of an aircraft with your GPS. For the record the number of proven instances of passenger's electronics affecting an aircraft over the last 25 years are very few across the entire world jet fleet. (single digits) olewill
Are laptops and electronic games not normally permitted on Oz aircraft then?
It does take a while to receive a signal presumably because of the speed of the aircraft but it does help in trying to identify ground features.
