Investigating Pilot Performance Using Mixed-Modality Simulated Data Link
Empirical studies of general aviation (GA) pilot performance are lacking, especially with respect to envisioned future requirements. Two research studies were conducted to evaluate human performance using new technologies. In the first study, ten participants completed the Modified Rhyme Test (MRT) …

Supporting Pilot Performance With an Integrated Flight Path Head -Up Display
… its head-down counterpart. In two experiments, performance with a HUD was compared to performance head-down, and pilots performed a series of simulated tasks in low and high visibility. The results indicate that while detection of events is generally enhanced by the HUD, tracking is influenced …

Multi-Method Approach to Understand Pilot Performance in a Sociotechnical Aviation System
This research examined human-machine performance in a General Aviation (GA) environment under dynamic conditions using a combination of field study and laboratory experimentation. Using this combination of methods, the functional system of pilots performing a landing approach (both instrument and …

The Use of Expert Pilot Performance Models to Facilitate Cockpit Visual Scan Training
… same 7-segment task as in Experiment I. Tracking performance and scan data were analyzed. The results suggest that whereas PTT without mental model development training (bottom-up PTT) provided limited benefits to flight performance, top-down mental model building appears to rapidly foster …

The Effect of Display Design on Pilot Performance in Controlled Flight into Terrain Scenarios
… enough for the General Aviation private pilot with minimal instrument training. This experiment attempted to examine how pilots of every experience level use and interpret the depiction of synthetic terrain to recognize and avoid potential CFIT situations. The outcome of CFIT was measured …

Active Noise Reduction Versus Passive Designs in Communication Headsets: Speech Intelligibility and Pilot Performance Effects in an Instrument Flight Simulation
… and potentially damaging sound environments to a pilot's hearing. Yet, another potentially more ominous result of this noise-intense environment is the masking of the radio communications. Radio communications must remain intelligible, as they are imperative to the safe and efficient functioning …
