Simplified Hazard Area Prediction Method - SHAPe

Kurzfassung

Wake encounter severity criteria are of great importance for any wake vortex related severity assessment. A simplified hazard area approach is developed employing validated simulation models. By applying one simple criterion, the roll control ratio, safe and undisturbed flight operations can be ensured. A limit value for manually flown (not controller augmented) aircraft for the approach flight phase is derived from piloted trials. As the required aircraft data for this severity assessment is not necessarily readily available for all aircraft of interest, there is a need to obtain this input data. With the Simplified Hazard Area Prediction Method (SHAPe), the required aircraft data is provided for a given maximum takeoff weight (MTOW) as the only input parameter required. Hence the SHAPe method can be universally applied for a safety assessment of wake vortex separation concepts and wake vortex advisory systems for improved air traffic management.
