Successful CDO Simulation Trials at AIR Lab
1 May 2024
AIR Lab successfully completed Continuous Descent Operations simulation trials, a major milestone in sustainable aviation research.
During late April 2024, AIR Lab conducted simulation trials for Continuous Descent Operations (CDO) using the T-SIM simulator. Two controller groups participated, each consisting of two Area Control Centers and one Approach control unit. Coaches from CAAS provided guidance, while ATM specialists managed the three-day event, including observations, simulator setup, templates, and performance metrics.
Objectives
The main objective was to evaluate and refine CDO procedures through realistic simulations, gather feedback on the latest developments, and build controller confidence in the CDO Advisory Tools. The initiative aimed to identify improvement opportunities for real-world implementation.
How the Trials Were Run
Trials were conducted using direct and flight level clearance commands across three template versions:
- No CDO
- CDO 2023
- CDO 2024
This combination produced nine exercises per controller group.
Results
The trials showed reduced controller workload during CDO sessions compared to non-CDO operations. The 2024 CDO version demonstrated improved descent level accuracy relative to the 2023 version. Controller questionnaires reflected positive feedback on the 2024 features and performance, indicating strong potential for successful operational implementation.
Insights from these trials will guide procedural refinements in upcoming development cycles, supporting more efficient and sustainable air traffic management.
