LAPARTS Report Summary

Project ID: 714917
Funded under: H2020-EU.

Periodic Reporting for period 1 - LAPARTS (LArge Passenger Aircraft Reliable Touch Screen.)

Reporting period: 2016-09-01 to 2018-02-28

Summary of the context and overall objectives of the project

The purpose of LAPARTS is to develop a Touch Screen Control Panel (TSCP) system that can host all functionalities currently hosted on the Overhead Control Panel (OCP). The OCP today consists of numerous electro-mechanical switches, buttons, knobs and annunciators connected with discrete wires to the aircraft systems. The current state of art of OCPs has several issues with ergonomic, economic and environmental implications.
The TSCP system will address these issues while hosting highly safety critical functions. The TSCP system will be compatible with up to catastrophic failure conditions and will secure the control chain from the touch sensor to the controlled system and back to the display.
In a first phase (ending Aug. 2019), TSCP prototypes will be integrated and evaluated in an enhanced cockpit simulator and potentially flight test platforms, targeting an evolution of the cockpit for existing aircraft. In a second and conditional phase (ending end of 2023), the TSCP will be integrated and evaluated in a disruptive cockpit simulator, targeting a revolution of the cockpit for deployment in future aircraft at the longer term. The TSCP will be developed following a user centered design methodology paying a lot of attention to human factors and end user interests. LAPARTS will adopt a sophisticated combination of projected capacitive and force sensing technologies in the touch screen in order to achieve the required safety levels while preserving user comfort.
LAPARTS will contribute to WP3.1 of the LPA IADP (tactile HMI), including weight reduction, manufacturing and usage cost reductions and recommendations towards the certification authorities. LAPARTS will also advance touch screen technology for use in turbulence conditions and safety critical applications.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

The following work has been realized during the first period of the project:
• The project plan has been established and is describing the WBS, the schedule, the management plan and the identified risks.
o The different work packages for this project are:
WP1 - Detailed project plan
WP2 - Definition of requirements
WP3 - Validation & verification plan
WP4 - System definition
WP5 - System validation
WP6 - System verification and operational evaluation
WP7 - Conditional system integration in disruptive cockpit demonstrator
WP8 - Low TRL technology maturation and de-risking
WP9 - Final report
WP10 - Management and Dissemination
• The System requirements have been defined. The Current A350 cockpit has been used as a use case and the requirements towards interfaces and functionalities have been formalized.
• The Human-Machine Interface concept has been defined. The list of functions to be realized has been established and several workshops and reviews with HMI experts and pilots have been realized to define the appropriate display configuration and interaction means. Focus has been put on reducing pilot workload and guarantee correct operation. The required safety features have also been identified. This activity resulted in defining the required widgets and various pages in order to support the overall control panel functions. Opportunities to implement context based features have also been identified.
• 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. The appropriate technology to implement force sensing feature on top of traditional Projective capacitive touchscreen has been defined.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

The main progress beyond state of the art is related to the support of catastrophic failure conditions:
• A touchscreen based overhead control panel system architecture supporting catastrophic failure conditions has been established.
• The required touchscreen technology and concept to compensate limitations existing with traditional touchscreen implementation has been defined and further derisked in order to support multi-touch functions and catastrophic failure conditions.
The expected impacts of this project are:
• A more efficient execution of flight, resulting in lower crew’s workload and improved safety.
• An easy and intuitive way to interact with the system through touchscreens
• A higher reliability and better maintainability
• A cost reduction of the overall control system
