ROLLOUT AND TURNOFF (ROTO) GUIDANCE AND INFORMATION DISPLAYS: EFFECT ON RUNWAY OCCUPANCY TIME IN SIMULATED LOW-VISIBILITY LANDINGS

This report examines a rollout and turnoff (ROTO) system for reducing the occupancy time for transport aircraft in low visibility weather. Simulator runs were made to evaluate the system that includes a head-up display (HUD) to show the pilot a graphical overlay of the runway along with guidance and steering information to a chosen exit. Fourteen pilots collectively flew a total of 560 rollout and turnoff runs using all eight runways at Hartsfield Atlanta International Airport. The runs consisted of 280 runs for each of 2 runway visual ranges. For each visual range, half the runs were conducted with the HUD information and half without. For the runs conducted with the HUD information, the runway occupancy times were lower and more consistent. The effect was more pronounced as visibility decreased.
