This study evaluated the attitude information conveyance of a new aircraft attitude display concept. The new symbology format, called the THETA symbology, was developed by integrating the shape of the conventional ADI and the transparency of the HUD into a single format. This research addressed whether or not there was a significant performance advantage or decrement incurred by the symbology integration. The THETA symbology, ADI, and HUD were evaluated during an attitude maintenance task and an attitude recovery task. The results of the study suggest few differences between the THETA and ADI formats while performance and training time were better with both the THETA symbology and the ADI than with the HUD format. The findings of the study lend support to the hypothesis that an attitude display formed of the integration of ADI and HUD type symbology will demonstrate a performance benefit over a pure HUD format.
