Short Biography

Max Friedrich received his Master of Science in psychology in 2015 from the Technische Universität Braunschweig, Germany. Since September 2015 he has been conducting his PhD as a scientist at the Institute of Flight Guidance of the German Aerospace Center (DLR). His research focusses on human-machine interface design concepts for supervisory control of multiple unmanned aircraft systems from one ground control station. In 2018 he conducted a semester abroad at NASA Langley Research Center as a visiting researcher.

The RESPONDRONE project develops and evaluates a multi-UAS platform to accelerate situation assessment and ease decision making during natural disasters. In order to assure that the multi-UAS platform meets the needs of the end-users, first response organizations are part of the project and closely involved in the design, development and evaluation of the platform. As one of the first steps in the project, a mock-up of the multi-UAS platform’s user interface was developed, which consists of two displays, one being a display for an on-site command center and the other a mobile application for the first response units in the field. Both displays were initially evaluated by eight subject matter experts in an online study and received good to excellent ratings regarding usefulness, usability and ease of use of the systems. The results are currently being incorporated into the displays and further evaluations are planned with the improved mock-ups.

The envisioned introduction of autonomous Small Unmanned Aircraft Systems (sUAS) into low-altitude urban airspace necessitates high levels of system safety. Despite increased system autonomy, humans will most likely remain an essential component in assuring safety. This paper derives, applies, and evaluates a display design concept that aims to support safety risk monitoring of multiple sUAS by a human operator. The concept comprises of five design principles. The core idea of the concept is to limit display complexity despite increasing the number of sUAS monitored by primarily visualizing highly abstracted information while hiding detailed information of lower abstraction, unless specifically requested by the human operator. States of highly abstracted functions are visualized by function-specific icons that change hue in accordance to specified system states. Simultaneously, the design concept aims to support the human operator in identifying off-nominal situations by implementing design properties that guide visual attention. The display was evaluated in a study with seven subject matter experts. Although preliminary, the results clearly favor the proposed display design concept. The advantages of the proposed design concept are demonstrated, and the next steps for further exploring the proposed display design concept are outlined.

Methods from cognitive work analysis were applied to investigate impacts of transitioning from conventional to remote aircraft control on function allocation and information accessibility. An abstraction hierarchy for an Airbus A320 was constructed, followed by an analysis of work functions and function allocation between pilot flying, pilot monitoring, and automation during approach and landing phases. Next, it was analyzed how removing the pilots from the flight deck to a remote location might affect the accessibility of important information that conventional pilots use for decision-making. The results revealed function specific information remote pilots have limited access to, which however seem to be important for decision making (such as visual cues from the environment). Furthermore, based on a supervisory control concept, a function reallocation between one pilot and automation was developed. The analyses contribute to deriving information requirements for remote pilot stations designed for remote single pilot operations in controlled airspace.
