► three variants of coordination-based conflict resolution algorithm - 1 centralized/serial and 2 distributed variants ► millisecond solve times for real-time application for multiple aircraft ► robust distributed system for practical conflict avoidance
● RPAS are not as disruptive technology as they seem to be - “Fly-by-wireless” and “Fly-by-wire” architectures are very similar ● Trajectory-based Operations: - Enablers of the future ATM deployed by SESAR and NextGen - Discussed and experimented with manned aircraft for 25+ years • Lots of results and lessons learned - Can be easily adapted and facilitate RPAS insertion into ATS: • Specific procedures,...
● NextGen and SESAR offer an unique (“technological”) opportunity ● The approach to security and a security capability is not addressed due to political and operational priorities ● GAMMA addresses this void offering “dual use” / complementary solutions to SESAR ● GAMMA developed a Security Situation Management Concept of Operations that allows for • a modular / iterative implementation and build...
□ Multicore only feasible path forward to improve processor performance □ Separation ◻ Provides safety and security by isolating independent functions and providing well-defined and characterized channels for interaction between those functions ◻ Reduces likelihood of covert side channels (security breach) as well as reducing chances of unanticipated consequences or failures (safety violation). □...
New RPAS mathematical modeling • Propeller model based on fluids mechanics and rotor electric circuit analysis; • Load model based on Pendulum-Spring. • Using quaternions we can control the aircraft behavior in critical conditions (no singularities - Gimbal Lock). • Initial simulation results.
TAS-I is working on these two evolution paths according to own roadmap tools and test-beds for aeronautical SoL services for manned and remotely piloted aircraft
• Time and Energy managed operations (TEMO) as a solution for environmentally friendly procedures in high-density TMAs • Importance of wind and real atmosphere accurate modeling to achieve very demanding time accuracies. • Smooth (continuous and twice differentiable) functions required in most numerical methodologies • WEMSgen successfully tested in human-in-the-loop real-time simulations • Flight...
• PBN to xLS simulations in 5 different aircraft types with lateral errors (−0,15NM – 0,15NM) and non-standard temp. (ISA-37 - ISA+35) • End point of RF connected directly to Final Approach Point (FAP) worked fine under the following conditions: • Standard glideslope of 3° • G/S is intercepted from a vertical path with shallower slope (e.g. 2°) • FAP at minimum 5NM from threshold (2NM required for...
● Extended routes were successfully used with the TSS tool suite and the DSAS tool and appropriate procedures were developed ● Extended routes reduced time in departure queue for 757s without impacting arrivals or departures ● Operations were judged as safe ● The number of clearances and workload increased for all controllers, but to a moderate and acceptable level - Increased workload in extended...
● Single pilots test / multi crew test ● McRuer's Law and McRuer's Crossover law ● Test scenarios/procedure ● Altitude drop ● Design of the test scenario ● Test subjects ● Data ● Interpretation and pilot model determination ● Best fits / Tool: determine bad design of the scenario ● Aim: determine the level of pilot's training
● Assess the tradeoffs between automation visibility and increased pilot workload and task times ● Assess the impact of aggregate information automation systems
■ OpenSky provides a scalable, open, and collaborative architecture for air traffic research. ■ Communications security is an important problem in modern aviation. ■ Our research using OpenSky proposes and analyses attack detection using several different approaches. ■ Security and privacy has been OpenSky's main theme but the data is used for many other applications now. ■ Check out http://opensky-network...
