Integrated Modular Avionics (IMA) platform and modules, hosting many functions that have been historically in functionally and physically separated systems, are being installed on new and modified aircrafts. EUROCAE ED-124 and RTCA DO-297 recognizes an incremental acceptance process for obtaining credit toward approval and certification by finding that an IMA modules, hosted applications, on/or off-aircraft IMA system comply with specific requirements. FAA TSO-C153 was released in May 2002 and has been accepted as main guidelines to authorize IMA hardware modules. To meet the demands of increasing application and certification of IMA platform and modules, EASA and CAAC have successfully released technical standard orders in 2016, respectively ETSO-2C153 for IMA platform and modules and CTSO-C153 for IMA Hardware modules.

Process based Assurance (or Development Assurance, DA), is one possible means for show compliance in Aircraft, System, Software and Hardware area. DA behaves different in ways and technologies when used in different area. That takes challenges for both applicants and certification authorities to demonstrate and evaluate compliance to Civil Aircraft Regulations. Both FAA/EASA and CAAC now try to propose some principles for DA involvement, and maybe take changes in futures certification activations.

Virtual flight testing and certification (VFTC) technology has a proven track record of successful validations and applications for a number of aircraft types and design projects. The goal of VFTC is to predict branching dynamics of the 'pilot/automaton - aircraft - operating environment' system and evaluate the system's safety performance in complex (multifactor, off-nominal, critical, hazardous, anomalous) or unknown flight situations - before an aircraft is built/flown. The technology's exploratory power is due to the synergy of high-fidelity mathematical modeling, fast-time simulation, situational control, artificial intelligence, knowledge mining and mapping, and some other techniques. VFTC is thought to become a 'bridge' between a vast library of potentially unsafe complex/unknown flight situations (baseline scenarios exacerbated by the presence of several risk factors) and latest achievements in computing and information technology.

The 3D electromagnetic (EM) simulation is a well-accepted design and development method for many applications. Microwave and RF engineers are using EM simulations since the 70th of the 20th century. But that’s different for EMC engineers. Still today testing is the preferred method. Often testing and simulation are even considered as competitive. But both methods have pros and cons and it’s advisable to benefit from both. International authorities as FAA and EASA set basic requirements for safe aircraft operation in harsh EM environments as HIRF and lightning. To demonstrate compliance aircraft testing is used which is expensive, time-consuming and only possible when mock-ups are available. It’s important to note that solving design issues late in the development phase of an aircraft can become very expensive. But today it’s also possible to use digital mock-ups in computer simulation and visualization.

Reducing CO2 emission is the key global issue to maintain human sustainability. At the automotive sector, further engine evolution is required. Internal combustion engines still have several losses such as cooling and exhaust losses and so leave much room for improving fuel economy. Mazda has been working on further fuel economy improvement by focusing on seven main control factors. This presentation provides the future steps to close to the ideal internal combustion engines in terms of the thermal efficiency. As an example of control factors, the heat transfer to combustion chamber walls is focused and some applications are shown by CAE and experimental analysis.

Transport is and will continue to be largely powered by petroleum-based liquid fuels. Alternatives start from a low base and are mostly relevant to passenger cars generally powered by spark-ignition (SI) engines using gasoline. The expected increase in global demand for transport energy will be significantly skewed towards diesel and jet fuel rather than gasoline. Abnormal combustion such as knock and preignition will become more likely as SI engines seek higher efficiency and gasoline antiknock quality will become more important. Such changes in fuel demand will pose big challenges to the refining industry and will likely lead to a surplus of low octane gasoline components. In efficient SI engines, for a given RON (Research Octane Number), a fuel of lower MON (Motor Octane Number) has better antiknock quality.
