An unavoidable consequence of aircraft lift generation is the formation of wake vortices – counterrotating air whirls which travel behind aircraft and pose a hazard to follower aircraft. Especially during approach and landing a wake vortex encounter should be avoided, given the limited reaction possibilities for pilots at low altitudes. In order to avoid such encounters, landing aircraft need to follow separations to one another. On the other hand, many airports are reaching their capacity limits. In the future, aircraft separations should be dynamic i.e. increase when a hazard is detected and decrease when it is possible to do so, resulting in an increase of efficiency and safety at airports, and as a direct consequence delivering more sustainable airport operations.
It is suggested to utilize LiDAR (Light Detection and Ranging) instruments as part of real-time wake vortex detection software to determine wake vortex positions and circulation strengths. Current analytical algorithms for LiDAR scan processing are not fast enough for real-time application, given that they are only partly automated.
As a result, the Institute for Atmospheric Physics at DLR Oberpfaffenhofen has started to employ artificial intelligence in the form of Artificial Neural Networks (ANNs) for the evaluation of LiDAR measurements. A unique and large labeled data set from a measurement campaign at Vienna International Airport in 2019 is available for the training of these ANNs. First studies have been conducted to find a suitable ANN architecture and evaluate the suitability of ANNs for this task. The obtained characterization precision and processing speed with ANNs for image processing motivate to perform further research in this field, with the ultimate goal of preparing ANNs for the real-time wake vortex characterization at airports. To reach this target, the ANNs have to become more robust, accurate and traceable. In the medium-term this provides increased safety and in the long-term higher airport efficiency.
