Which of the following is true regarding fly-by and fly-over GPS waypoints?

Fly-over waypoints are designed to be passed directly without any course reversal. They serve as points that an aircraft must reach, and they can often be fundamental points for navigation. The flight path allows for a direct transition to the next leg of the route upon reaching the waypoint. This is particularly advantageous in efficiently navigating the airspace.

On the other hand, fly-by waypoints require the aircraft to turn and maneuver to the next leg after passing the waypoint; however, they do not involve a complete reversal of course. Therefore, while fly-by waypoints facilitate smooth transitions during flight, they do not compare to the direct approach provided by fly-over waypoints.

The other options pertain to different characteristics or uses of waypoints that aren't relevant to the core difference between fly-by and fly-over waypoints, solidifying the understanding that fly-over waypoints can indeed be passed directly.
