If this aircraft has advanced avionics, then why does the captain have a handheld GPS ?

This bottom pic shows the advanced avionics of the aircraft

Maybe just for fun? Or calibrating it against the aircrafts instruments?

Isn't that done on the ground by mechanics ???

It is possible the plane uses GLONASS as well as GPS. Probably the handheld doesn't really affect the plane's avionics systems anyway.

So does that mean I could take a GPS aboard and use it ?

Could you, yes, should you; no! It probably won't interfere, but who knows if it is somehow shielded incorrectly or interferes through a defect of some kind. It isn't neccesarily that the devices normally would interfere, but they are not subject to the testing and certification of ones meant for aircraft. Many pre-GPS Soviet-era aircraft have ad-hoc GPS systems using handheld devices. Some can even correlate GPS and GLONASS (as an aside, doesn't GLONASS sound like something crude?)

GPS receivers are passive, and don't send out any signals above and beyond what might be expected from any battery-powered device (eg. cd player, MP3 players, etc.)



It only takes five years to go from rumor to standard operating procedure.
