Commercial planes don't do much with GPS. Flight systems are slaved to the Inertial Navigation System.

Another sibling post already talks about this.
Note that the only thing the plane can do is to warn.
- parsimo2010 7y agoThis isn't true any more. The vast majority of commercial flights navigate with GPS, and follow GPS waypoints with the AP. They are so accurate that international flights across the ocean apply SLOP (strategic lateral offset procedure) to the route so they don't run into each other.

- parsimo2010 7y agoCitation not needed. I'm a pilot. Inertial systems provide attitude and heading information, but is only a backup for navigation. INS cannot deliver the required navigational performance and is only used to cross-check GPS and to provide a backup in case GPS fails.
