Research in pilot scanning behavior

A NASA-developed oculometer, which measures pilot scanning behavior, is described in terms of design and operating parameters. Results are presented of tests conducted in a terminal configured vehicle (TVC) aft cockpit simulator, involving pilots making simulated instrument approaches. Attention is given to the amount of time the pilots spend scanning the SFD and EADI CRT displays, and to differences resulting from both the physical location of the CRTs (within a 30 x 30 x 30 cm space), and from their intrinsic characteristics.
