The intent of this study is to provide the helicopter operators a presentation of the airflow over the flight deck prior to the approach Phase Of Flight (POF). This capability has the potential to influence the decision making associated with the approach. Turbulent airflow visualization designs were created focusing on user centered design principles and usability heuristics. The designs were presented to experienced helicopter pilots and subjectively evaluated by the same pilots. Based on the evaluation results, a dynamic three dimensional (3D) design was selected for development of a Shear-Stress Transport (SST) turbulence model using the Simplifed Frigate Shape 2 (SFSll) geometry. The 3D model was created for further testing in a simulator.
The findings show interest exists within the helicopter pilot community for a capability to have identified where hazardous airflow is located over the flight deck and a more in-depth awareness of what the airflow is doing is desired.
