Urban Air Mobility and drone operations are growing quickly, bringing new challenges for managing automated traffic at vertiports. As more aircraft approach these sites, efficient sequencing of arrivals becomes essential to maintain safety and meet operational limits. Key constraints include separation minima, route availability, pad capacity, and the energy limits of each vehicle. Most current systems use deterministic, rule-based algorithms. These approaches offer predictability and are easier to certify, but they can struggle when many aircraft compete for limited vertiport resources. Recent developments in Reinforcement Learning (RL) suggest that learning-based solutions might improve efficiency by finding better sequencing and control strategies. However, RL alone raises concerns about safety, transparency, and certification. Combining RL with rule-based safety logic in a hybrid system is a promising path: RL proposes actions, while a deterministic layer enforces operational rules as a safety filter. Role overview This master thesis internship centers on investigating a centralized hybrid arrival management concept for drone and UAM operations at vertiports. The work will use the BlueSky open-source air traffic simulation environment to explore these ideas. Research focus Explore how a centralized hybrid architecture that integrates reinforcement learning optimization with deterministic safety logic can be structured for vertiport arrival management.
