The purpose of this paper is to report on a human factors evaluation of ground control station design concepts for interacting with an unmanned traffic management system. The data collected for this paper comes from recent field tests for NASA’s Unmanned Aircraft System (UAS) Traffic Management (UTM) project, and covers the following topics; worklo...

The purpose of this paper is to discuss a cognitive task analysis related to the task of the UTM manager with the goal of determining display requirements for that role. UTM is a project founded at NASA Ames which seeks to integrate and manage small UAS operations in the NAS. Specifically, the NASA UTM project goals are to enable safe and efficient...

A set of studies has been focused on identifying “markers” in aircraft data that are indicative of human factors issues. In this paper we discuss an experiment that investigated if human error is predictable from the error observed from the combined human-machine system. Sixteen pilots flew simulated instrument approaches under varying levels of wo...

This paper discusses the quality of a recommender system implemented in a simulation to assist with choosing a diversionary airport for distressed aircraft. In the third of the series of studies investigating the feasibility of ground-supported single pilot operations (SPO) a recommender system was used by 35 airline pilots as an aid for selecting...

Since the 1950s, the crew required to fly transport category aircraft has been reduced from five to two. NASA is currently exploring the feasibility of a further reduction to one pilot. In this study we examine the effects of separating the pilots on crew interaction. The results are consistent with earlier research on decision-making between remot...

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...

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 dyna...

The Next Generation Air Transportation System (NextGen) will revolutionize the air traffic management system in the United States. NextGen will involve human operators interacting with new technologies in a complex system, making human factors and human–computer interaction considerations a major concern. The present study reports data from a human...

In today's terminal operations, controller workload increases and throughput decreases when fixed standard terminal arrival routes (STARs) are impacted by storms. To circumvent this operational constraint, Krozel, Penny, Prete, and Mitchell (2004) proposed to use automation to dynamically adapt arrival and departure routing based on weather predict...

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 FANSequ...

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...

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-sepa...

A primary feature of the 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. FANS is presently the primary flight deck system in the US supporting TBO, but relatively few aircraft are FANSequipped. Thus any near-term implementation must prov...

This paper examines pilots' responses during a human-in-the-loop simulation to off-nominal conditions. During the simulation pilots used advanced flight deck tools to achieve automated spacing and merging assignments while in cruise, and prior to performing a continuous descent approach (CDA) into Louisville International Airport. The off-nominal c...

This paper reports on the performance and workload of pilots participating in a human-in-the-loop simulation of interval management operations during a continuous descent approach (CDA) into Louisville International Airport (SDF). The experiment examined variations in pilot roles and responsibilities in an implementation of interval management auto...

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 expos...

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. Three conflict avoidance management concepts were studied: pilot, controller...

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 o...

This paper introduces and describes a 3D Cockpit Situation Display (CSD) that includes the display of ownship and traffic, flight path intent, terrain and terrain alerting relative to current and proposed flight paths, conflict alerting and 3D weather. The primary function of the 3D CSD is to support the task of flight path management, although it...

Beach to assess the feasibility of flying ROVs in busy terminal environments with commercial traffic. Pilots with glass cockpit experience were recruited to fly one or two ROVs in simulated airspace over water reservoirs near DFW airport, with the major goal of avoiding the approach traffic. Results showed that pilots had a difficult time patrollin...

A distributed simulation of ROV operations was conducted by NASA Ames Flight Deck Display Research Laboratory (FDDRL) and the Center for Aeronautic Technologies (CSAAT) at California State University, Long Beach. The goals of this simulation were 1) to examine ROV operators' ability to maintain standard terminal separation from other aircraft and R...
