An easy-to-use and secure logger is available that records the pilots cross-country flight, including the waypoints of the set task, such that the tracklog can be analyzed to show successful completion of the flight and the associated completion time.

X-Plane provides a logging capability (details to follow).
sim_logger provides this capability for FSX.
