Alerting and conflict resolution. Additional research is needed with regard to the appropriate way of alerting pilots, the identification of a resolution manoeuvre and the necessary guidance for such a manoeuvre in case of airborne wake vortex system activation. • Human-Machine Interface and Human Factors of wake vortex alerting as well as conflict resolution. What is the best way (Human-Machine Interface and Human Factors) to warn the pilot and suggest a conflict resolution (visually and/or aurally)? It must be analysed how visual/aural warnings could be optimised to give the pilot the best situational awareness. • Concept and algorithm for the creation of avoidance trajectories taking into account terrain (TAWS), other traffic (TCAS) and own aircraft capabilities. Identification of an evasion trajectory for conflict resolution has to be optimised regarding computational effort (computation time) and deviation from the planned flight path. An optimised concept/algorithm for evasion trajectory generation needs to be developed which takes into account terrain (TAWS), other traffic (TCAS) and own aircraft capabilities. The benefits and feasibility to perform evasive manoeuvres in 3-D need to be evaluated (i.e. not only lateral or vertical evasion). Finally research is necessary to confirm whether a tactical approach (i.e., no change in flight plan) is generally sufficient for the avoidance manoeuvre.
