The purpose of this report is to evaluate pilot capability to fly air traffic control offsets and vertical profiles for both two- and three-dimensional area navigation RNAV modes both with and without the use of a flight director. Flight pilot subjects participated in simulation tests conducted at the National aviation facilities Experimental Center. Performance was measured for two varibles total system crosstrack error TSCT and flight technical error FTE and assessment was made of pilot performance on horizontal tracking, vertical tracking, and turns. The major findings were 1 2-sigma and 2-RMS steady state tracking data for centerline and offset tracking were within or - 1.5 nautical miles of the course being flown, 2 summary data for centerline turns never exceeded a or - 2 nautical miles error range, 3 centerline tracking was less variable than offset tracking, 4 the use of 3D RNAV mode to arrive at a specified altitude at a specific location increased pilot workload along the route segment leading to that location, 5 lag times for pilot response to ATC RNAV clearances were found to be a function of the situation complexity, and 6 the calculated RSS statistic proved to be an overconservative estimator of TSCT errors.
