A series of VOR-DME instrument landing approaches was flown in the Langley DC-9 Full-Workload Simulator to compare pilot performance, scan behavior, and workload when using a counter-drum-pointer altimeter (CDPA) and a digital altimeter (DA). six pilots executed two sets of instrument landing approaches, with a CDPA on one set and a DA on the other set. The DA consisted of five, seven-segment LED digits, 0.28 inch high. pilot scanning data were collected with an oculometer system. Thedoi:10.4271/841489 fatcat:7sdvf2gnlncsfcqoqe7ng2ibou
