Reducing high workload levels are a major challenge to enable single pilot operations. Where the pilot is currently supported with many automated systems, the role of mission planner is relatively unsupported, i.e., the flight crew is required to integrate and combine information from various sources to extract the implications on the missions’ high-level goals to determine if the mission can still be completed safely and successfully. An operational alerting display is developed to provide the pilot with a clear overview of the current and future operational flight constraints. This enables the pilot to determine if the initial plan is valid under the existing conditions. The display is not limited to system malfunctions, but combines the full spectrum of operational constraints, e.g., weather and airport operations. The display concept was tested on usability with a commercial pilot to provide a preliminary performance indication on the effectiveness of the concept.
