NLR is a leading international research centre for aerospace. Bolstered by its multidisciplinary expertise and unrivalled research facilities, NLR provides innovative and integral solutions for the complex challenges in the aerospace sector. For more information visit: www.nlr.nl NLR's activities span the full spectrum of Research Development Test & Evaluation (RDT & E). Given NLR's specialist knowledge and facilities, companies turn to NLR for validation, verification, qualification, simulation and evaluation. NLR thereby bridges the gap between research and practical applications, while working for both government and industry at home and abroad. NLR stands for practical and innovative solutions, technical expertise and a long-term design vision. This allows NLR's cutting edge technology to find its way into successful aerospace programs of OEMs, including Airbus, Embraer and Pilatus. NLR contributes to (military) programs, such as ESA's IXV re-entry vehicle, the F-35, the Apache helicopter, and European programs, including SESAR and Clean Sky 2.Founded in 1919, and employing some 650 people, NLR achieved a turnover of 71 million euros in 2016, of which three-quarters derived from contract research, and the remaining from government funds.

EXECUTIVE SUMMARY
Problem areaLoss of control in-flight (LOC-I) accidents, caused by an upset followed by a failure of the pilot to control and recover the aircraft, remain the largest contribution to fatal aircraft accidents worldwide. A reduction of crew stress (e.g., caused by an unexpected event in a safety critical situation) and high workload will contribute to further reduction of LOC-I related incidents. Modern civil transport aircraft are currently equipped with a flight guidance system that allows the aircraft to be flown automatically for most part of the flight. Future requirements from a flightdeck system-safety point of view include a more integrated design of information systems available to the pilot, including displays and interactions, flight decision support systems (e.g., advisories during upset conditions, including automatic recovery), and the allocation of functions between the pilot and automatic systems during nominal and degraded flight conditions. This new "intelligent" flight deck should be able to sense onboard (flight control) system and environment-induced hazards in real time, and provide the necessary and timely actions to prevent or recover from an upset.
