    Re: GPS jamming concerns

    This report is not a failure of the GPS system, on board or in the sky. It is a case of Human interface error. This has commonly been call pilot error but the issue is more complicated than that. In this case the crew entered west coordinate instead of east. It would be a simple thing to have the GPS unit ask for confirmation when a waypoint outside of the range of the aircraft is entered.  This would have been an improvement to  the system interface. And the kind of thing demanded of high reliability organizations. 

    In fact in the US if a standard departure procedure is not in the GPS data base it is illegal to use it. This is to prevent just this type of error.
