• The need: □Realistic air traffic scenarios containing conflicts and encounters for analysis of decisio support tools • The solution:□ Time shift real traffic scenarios □ Apply genetic algorithm to solve NP-complete problem
□ Identified reachable sets represent aircrafts capabilities □ Safe mode transitions can be determined □ Refined model provides greater situational awareness□ Verification of usability and accuracy through simulations □ Test flights
• Objective: To investigate the impact of transition airspace design on efficiency of flight operations that use the more efficient high altitude RNAV Jet routes (Q-routes)
• Slow to fast speed schemes were the hardest condition — 220kts at 25 000′ was the hardest speed reduction to achieve — Large variations from the profile increased crew workload
• NASA is sponsoring a multiple-area multi-year program for verification and validation of flight critical systems. • Objective — Provide advanced analytical, architectural, and testing capabilities to enable sound assurance of safety-critical properties
█ Proposed a CPS framework for aviation █ Enables informed use of cyber advances for aircraft and ATM █ Viewed future e-enabled aircraft and ATM systems as CPS instances █ Illustrated impact of CPS interactions on aviation performance █ Proposed an innovative CPS solution for aviation called group flight █ uses ADS-B and IP network links of two or more geo-proximate aircraft and combines them as a...
♦ The use of multicore in avionics requires new methods to enforce robust partitioning ○ ARINC 653 time partitioning is not applicable ○ Inter-partition true parallelism ○ Concurrent transactions management in the interconnect with few visibility on its behavior ○ Incremental certification objectives
□ The Terminal Area Precision Scheduling and Spacing system is robust for off-nominal missed-approach operations for up to 4 missed approaches in a 1-hour period
• Weather events can severely impact airspace system capacity • In response to weather, currently, TFM is used to balance air traffic demand with system capacity • Non-permeable weather modifies traffic patterns, which can make current sector design suboptimal • Apart from helping reduce workload imbalances due to higher traffic demand, DAC models can also be used to optimize airspace capacity as...
• Several promising concepts to support a human operator in closing the navigation loop find their origin in research performed close to and sometimes even over half a century ago • Some of them are conceptually superior to today's solutions but had to wait more than a quarter of a century for the required technology (in terms of cost, performance, size, weight and reliability) to become available...
□ Uncertainty in airport operations ▓ Can influence the airport performance ▓ Hard to plan aircraft movement accurately through deterministic optimization ▓ However, difficult to formulate or analyze its effects
• ANKA is a MALE class UAV • Designed to make the surveillance and target acquisition • Developed for day and night real-time intelligence • 24 hour endurance • 200 km maximum line of sight • 30,000 ft. maximum altitude • 10 m Fuselage Length and 17 m Wing Span • ATOLS
• Fundamental task of ATC • Ensuring that aircraft comply with instructed trajectory • Automated Conformance Monitor (ACM) — a proposed automation enhancement — compares aircraft trajectory to a published route — detects when aircraft deviates from assigned route — produces an alert to the controller
█ General needs in avionics • Increasing system flexibility • Reduction of system cost • Simplification of installation • Reduction of weight → less fuel consumption → lower operating costs
• Combined System for Harbor, Infrastructure and Littoral Domains (CSHIELD) project (2011–2013) • Dutch Society Innovation Agenda ‘Safety’ • Realize a concept and validation model of a small, potentially unmanned vessel for: • Patrol • Control • Information gathering • Anti-piracy • Securing of ships and maritime infrastructure, both at sea and in coastal and harbor areas • The design of the platform...
• SVS — Synthetic Vision System — a synthesized (rendered) image of a forward view of terrain/obstacles/runway from a database at the aircraft's present position & heading
Beaconing = broadcast of status information to vicinity — Applications in Aeronautics: — Automatic Dependent Surveillance Broadcast (ADS-B) — Collision avoidance — Neighborhood information broadcast for mobile ad-hoc networks
