Listening to the media pretend to understand how a 777 works hurts my ears.
All this talk about programming, or pre-programing a turn is based on what?
I can use the FIX page to install a LAT/LONG or a Published Intersection and then use heading select to steer to that point. I can also just use MCP heading select to simply steer, no FMC input required.
Did this flight use CPDLC/ADS, FANS 1/A? Did the flight's FMC downlink a changed route via ACAARS (and if so why don't they look at the last waypoint in that downlink)? If CPDLC was used, there is the ability to uplink a new route, and if the crew accepted and executed an upload the aircraft would fly that route (on AP).
Just curious how sure they are of a pilot installed/uplinked a FMC flight plan vs. a heading select course on AP.
PS. To the media cursing this thread for info, please stop embarrassing yourselves.
