Volpe National Transportation Systems CenterUnited States. Federal Aviation Administration. NextGen Human Factors Research and Engineering Division (ANG-C1)Volpe National Transportation Systems Center, Technical Reference CenterThis paper describes analyses of vertical and lateral deviations in the North Atlantic (NAT) Region. We focus on events attributed to unintentional pilot error. We studied NAT deviations since this region already uses some of the capabilities envisioned under Trajectory Based Operations (TBO), such as Controller-Pilot Datalink Communications (CPDLC) and half-degree waypoint coordinates for latitude and/or longitude. Half-degree waypoints could be used for dynamic routes under TBO; CPDLC may be used to communicate this information.82
