Foundational Terminal Operations HITL: Experimental Design Slides

The UAS (Unmanned Aircraft Systems) in the NAS (National Airspace System) project is conducting its first investigation of UAS operations in the terminal environment. A workshop is being held to get input from key stakeholders on the experimental design and scenario development occuring for this simulation, which intends to begin data collection in September 2017. These slides cover the proposed design and methodolgy for the experiment.

Effects of Type and Strength of Force Feedback on Movement Time in a Target Selection Task

Future cockpits will likely include new onboard technologies, such as cockpit displays of traffic information, to help support future flight deck roles and responsibilities. These new technologies may benefit from multimodal feedback to aid pilot information processing. The current study investigated the effects of multiple levels of force feedback on operator performance in an aviation task. Participants were presented with two different types of force feedback (gravitational and spring force feedback) for a discrete targeting task, with multiple levels of gain examined for each force feedback type. Approach time and time in target were recorded. Results suggested that the two highest levels of gravitational force significantly reduced approach times relative to the lowest level of gravitational force. Spring force level only affected time in target. Implications of these findings for the design of future cockpit displays will be discussed.
