The following work has been realized for the enhanced cockpit phase:
• The project plan has been established.
• The System requirements have been defined.
• The Human-Machine Interface concept has been defined.
• The preliminary safety analysis has been realized resulting in the definition of an architecture compliant with failure conditions up to catastrophic.
• Touchscreen technology to support multi-touch and catastrophic failure conditions has been further derisked.
• 2 main prototypes have been developed:
o The Force sensing prototype consists in a display equipment with dedicated PCAP touchscreen augmented by an adaptive force sensing module and hosting an application demonstrating the usage of such function.
o The HMI prototype consists in a system of 3 touchscreen displays positioned in overhead location and an advanced application realizing critical control functions using a smart page concept.
• The overall enhanced cockpit phase has been concluded by a Validation and Verification activity realized according the V&V plan.
o On a mockup representative of the A350 cockpit, the first demonstrator has allowed us to evaluate the ergonomics of touch screen displays to control systems to study the feasibility of the replacement of the overhead panel. The overall concept of this demonstrator has given very good results in terms of HMI and robustness.
o The second demonstrator provides the opportunity to evaluate the Force Sensing technology on a touch screen display to offer dissimilarity for critical commands and cope with safety objectives. The Force Sensing technology has given promising results from the performed tests.
• The results of these evaluations are used to identify the improvements to introduce during the disruptive cockpit phase.
The disruptive cockpit phase has been further developed:
• The project plan for disruptive cockpit has been defined.
• The V&V plan for disruptive cockpit has been defined.
• The Requirements and System definition for disruptive cockpit have been established.
• The 18,5" display prototype has been developed, assembled and integrated with A/C system.
• The application framework based on Arinc 661 part 2 and SIMPhony framework has been developed and integrated
• The safety analysis for the disruptive cockpit phase display has been realized.
• The 18,5" display with dissimilar touch technology and the new HMI have been successfully validated in a vibration environment bringing the technology to TRL5.
Dissemination
The following dissemination activities have been realized during the project
• A detailed presentation of LAPARTS project has been given during Aeropsace Tech week 2023 in Munich on 29/30 March 2023. Link to the video:

ScioTeq is exploiting the various results of the LAPARTS project as followed:
• Displays in overhead location is identifed as a potential new product item in our portfolio
• The safety critical system being defined during this project is being further applied in various ScioTeq projects
• The knowledge being built in dissimilar touchscreen solution is used in the design of all new ScioTeq products with touchscreen technology.
• The dissimilar touchscreen solution is being promoted as a new product item in our portfolio (DAL A touchscreen display)
• Arinc 661 part 2 is promoted as a new feature of our products.
