Aircraft Wake Vortex State-of-the-Art & Research Needs, Kapitel 4.2 Airborne Systems

Kurzfassung

Airborne systems for wake vortex detection, prediction, warning, avoidance and impact alleviation are envisioned to enhance safety during all phases of flight. This specifically includes the cruise flight phase, during which relevant wake vortex encounters are reported regularly. In general, three basic embodiments of airborne wake vortex systems can be distinguished: - Wake encounter alerting with and without avoidance based on (probabilistic) wake vortex model predictions and enabled by advanced air-to-air data exchange - Wake encounter alerting with and without avoidance based on mid to long range forward-looking wake vortex sensors - Wake impact alleviation based on advanced flight control techniques enabled by short range forward-looking sensors and/or online wake characterization.
