Noise Abatement Fms with Tactile Interface

Periodic Reporting for period 2 - NAFTI (Noise Abatement Fms with Tactile Interface)

Reporting period: 2018-12-01 to 2020-05-31

In May 2015 and as part of Clean Sky (CS1), Airbus Helicopters (AH) demonstrated with a H175 helicopter a noise footprint reduction of up to 30 per cent by using lownoise helicopter Instrument Flight Rule (IFR) approaches to the heliport. This demonstration was based on the noise optimised flight paths for conventional helicopters. This was one of the Clean Sky (CS) initiative’s high-level goals.

Airbus Helicopters now aims at achieving similar noise reduction objectives for the RACER compound aircraft demonstrator as well as reducing the crew workload to enhance safety. It is expected that the RACER aircraft will support more flexibility for noise abatement flight procedures thanks to its traction propellers. However, more complex flight procedures require to maintain or reduce the workload. Reduced noise on approaches is benneficial to the surrounding environment.

The main NAFTI objective is to develop, manufacture, test and qualify up to safe for flight status a FMS with noise abatement functionality. NAFTI will enable the demonstration of the automated noise abatement flight procedures (i.e. quiet flight demo). The FMS will support all capabilities of the flight management and guidance system that is in use on AH products today plus an additional plug-in for specific complex low noise trajectories.

NAFTI will enable the RACER (and more generally other rotorcrafts) to operate in low visibility conditions of urban environments and busy airports. Therefore the FMS will contribute to the risk reduction for collisions with terrain, structures or other traffic by decreasing the time needed for heads-down FMS interactions and by increasing the situational awareness.

NAFTI’s will also demonstrate the potential for touch screen technology to provide a flexible platform to integrate other control panel functionalities with a more efficient user interface. Additionally, such integration will contribute to the reduction of cost and weight (and thus fuel consumption and emissions) and to the increase of RACER aircraft dispatchability (thanks to higher overall system reliability). Reduced weight ultimatley reduces fuel burn and as a result reduces the environmental impact & operational cost.
"Preliminary safety analysis completed.

Prototype 4""x5"" Touchscreen Control Units (TSCU) designed and manufactured. Preliminary environmental and EMI testing performed. TSCU validated for installation on the RACER aircraft. TSCU has demonstrated high performance processing, high performance graphical processing and large quantity of electrical interfaces including video in and out is possible within a small volume. The TSCU is an incredibly versatile unit. The TSCU has also maintained it's backwards compatibility with the CMA-9000 FMS incl. a 10% weight reduction.

Preliminary FMS HMI evaluation completed with Airbus Helicopters.

Control panel virtualization also demonstrated showing the potential to virtualize 5 or 6 center pedestal control panels thanks to the processing power, A653 partitioning and large quantity of TSCU physical Interfaces. This demonstrates a potential aircraft weight saving and cost of ownership reduction.

Dissemination activities started including Le Bourget airshow."

A unit weight reduction of 10% achieved also leading to overall aircraft weight reduction.
