Flightcrew Thrust Control and Engine Display Concepts for the Subsonic Single Aft Engine (SUSAN) Transport Aircraft

NASA is developing a new hybrid-electric aircraft concept called the SUbsonic Single Aft eNgine (SUSAN) Electrofan. The SUSAN airplane is being designed as a 180-passenger commercial regional jet and is expected to fly in the 2040 time frame. The flight deck of the SUSAN airplane is expected to resemble a typical two flightcrew transport. Research issues include pilot control and the display elements needed for the hybrid-electric propulsion system. This paper describes a research study conducted in a high-fidelity simulator where 14 commercial pilots evaluated throttle controls and engine display concepts for a proposed SUSAN flight deck. The results showed that the number of throttle levers did not affect pilot’s situation awareness, workload, or speed control.

Single Throttle Design for the Subsonic Single Aft Engine (SUSAN) Transport Aircraft

NASA is conducting trade studies for a new hybrid-electric aircraft concept called the SUbsonic Single Aft eNgine (SUSAN) Electrofan. The SUSAN airplane is being designed as a 180-passenger commercial airplane and is expected to fly in the 2040 time frame. The flight deck of the SUSAN airplane is envisioned to resemble a typical two person flightcrew transport. Pilot control research issues include interfaces and display state elements needed for the 17 engine hybrid-electric propulsion system. A pilot study was conducted where one, two, and three throttle handles were the independent variable in a simulation experiment. The results from the study showed that the three throttle concepts were equivalent in terms of workload, situation awareness, and thrust control. However, the pilots rated the usability of the single throttle test case to be “good” compared to the rating of “excellent” for the two- and three-throttle cases. From these results, a follow-on pilot study is described to explore a redesigned single throttle concept with associated engine display concepts.
