A multidisciplinary team of academics, flight safety experts, pilots, flight simulation engineers and human factors specialists adapted the Boeing 737 Next Gen simulator Airfox UPRT at AMST, Ranshofen, Austria to be capable to `inject' a variable wake vortex encounter (WVE) in cruise flight and measure the effect on a type-rated operating crew. As part of the EU SAFEMODE project (2019-2022), this was used to carry out a validation study for the use of new Air Traffic Control (ATC) cruise wake alerting procedures. Developed at DMU, the flight simulation model for the extended flight envelope allowed continuation of flight simulations in case of onset of high angles of attack and stall conditions following WVE. Along with facilitating the validation of new ATC procedures, the flight data also provided insights into pilot upset prevention and recovery training (UPRT) in the era of recurrent academic and flight training for upset prevention and recovery.
