Enhanced flight safety, efficiency and airspace capacity by reducing controller workload and minimising congestion on voice communication channels.
CPDLC provides an additional communication channel beside the regular VHF channels. It helps to reduce the workload of controllers thus increases capacity and the level of safety taking advantage of the clarity of text messages. Last but not least, increased capacity means increased efficiency as well.
The regular changes in air traffic demand ANSPs to stay flexible and adapt their procedures as necessary since optimal and effective procedures are essential for successful operations.
Providers have to meet new requirements such as reduction of fuel consumption, mitigation of emission and improved noise abatement. At the same time safety, regularity and efficiency of air traffic have also to be maintained.
The growth in air traffic brings more and more conflicts at the intersections of routes, departure and arrival procedures. Solving these situations involves increased amount of radio communication and increases the workload on the air traffic controllers thus reducing their capacity to deal with efficiency as well.
In many ATC sectors the congestion on voice communication radio channels has become by today a bit of a bottleneck limiting the available capacity of the airspace.
CPDLC provides an additional communication channel that reduces the occupancy on the regular VHF channels. It not only reduces the workload of controllers thus increases capacity and the level of safety itself but CPDLC has more to offer: It provides unambiguous means of communication by text messages that raise the level of safety even higher. On the other hand increased capacity means increased level of efficiency as well.
The HMI reproduction capability of our state-of-the-art Real-Time Simulation platform can serve as a test-bed for prototyping CPDLC HMI solutions.
Validation traffic scenarios are designed according to these attributes.
may also be used to assess preliminary results. We record all relevant parameters, such as total and specific numbers for distance and time travelled, fuel burnt, noise strain, entry rate and occupancy of different airspace sections, air and ground delays, utilisation of available capacities, number of conflicts. Customised statistics can also be created; even controllers’ workload factors can be estimated through Artificial Intelligence.
on our state-of-the-art simulation platform that reproduces the HMI of their “home” ATM system.
The results of this validation will be drawn from the same set of parameters that are recorded during the simulation together with specific “Human-in-the-Loop” parameters such as objective data for number and length of radio and telephone calls, number of co-ordination events, number of medium and short term conflict alerts, number of specific instructions performed through the HMI (direct clearance, turn, speed and level change, etc.). Also subjective workload assessment (ISA) data is gathered as well as subjective reflection on safety issues, hotspots, procedures, workload and situational awareness through questionnaires (NASA-TLX, SASHA-Q).
The simulation environment prepared for the validation can be utilised later on for the training of air traffic control personnel.
Following the implementation of the solution the real change of the relevant parameters can be evaluated from real-life recorded data through Fast-Time Simulation and the solution can be fine-tuned as necessary.
