Pilotage errors in area navigation were measured both in flight and in a flight simulation laboratory. Experimental procedures were designed to test instrument pilots under relatively demanding flight situations representative of IFR terminal area and final approach operations. Experimental display variables include linear versus angular steering error indications, steering error scale factor, and integrated versus separated presentations of heading and course deviation. Although the data are preliminary, steering error magnitudes were generally consistent with those assumed in Advisory Circular AC 90-45 provided an appropriate scale factor is used. Relatively frequent procedural blunders occurred in the operation of currently typical RNAV controls. Pilot performances in the simulator were comparable to those observed under similar task conditions in flight, thereby supporting the use of the simulator in more systematic studies of display, control, and procedural variables in area navigation.
