This study compared situation awareness across three flight deck decision aiding modes. Pilots resolved air traffic conflicts using a click and drag software tool. In the automated aiding condition, pilots executed all resolutions generated by the automation. In the interactive condition, automation suggested a maneuver, but pilots had the choice of(More)
The Federal Aviation Administration hopes to convert air traffic management to Trajectory Based Operations (TBO), under which aircraft flight plans are known to computer systems which aid in scheduling and separation. However, few aircraft flying today have equipment designed to support TBO. We conducted a human-in-the-loop simulation of TBO using current(More)
This study compared pilot situation awareness across three traffic management concepts that varied traffic separation responsibility between the pilots, air-traffic controllers, and an automation system. In Concept 1, the flight deck was equipped with conflict resolution tools that enable them to perform the tasks of weather avoidance and self-separation(More)
The number of crew members in commercial flights has decreased to two members, down from the five-member crew required 50 years ago. One question of interest is whether the crew should be reduced to one pilot. In order to determine the critical factors involved in safely transitioning to a single pilot, research must examine whether any performance deficits(More)
Managing the interval between arrival aircraft is a major part of the en route and TRACON controller’s job. In an effort to reduce controller workload and low altitude vectoring, algorithms have been developed to allow pilots to take responsibility for, achieve and maintain proper spacing. Additionally, algorithms have been developed to create dynamic(More)
In this study, pilots were asked to achieve a specific time in trail while flying an arrival into Louisville International airport. Weather shortly before the start of the descent added variability to the initial intervals. A spacing tool calculated airspeeds intended to achieve the desired time in trail at the final approach fix. Pilots were exposed to(More)
A primary feature of the Next Generation Air Transportation System (NextGen) is trajectory based operations (TBO). Under TBO, aircraft flight plans are known to computer systems on the ground that aid in scheduling and separation. The Future Air Navigation System (FANS) was developed to support TBO, but relatively few aircraft in the US are FANS-equipped.(More)
Pilot workload was examined during simulated flights requiring flight deck-based merging and spacing while avoiding weather. Pilots used flight deck tools to avoid convective weather and space behind a lead aircraft during an arrival into Louisville International airport. The study examined concepts placing conflict avoidance responsibility on different(More)
