“…These form the basis for both prevention techniques and recovery procedures, which are then practiced on Flight Simulator Training Devices (FSTDs). Unfortunately, current technology only allows limited simulation of LOC in FSTDs, as extended flight envelope models are still being developed [22][23][24]. Finally, on-aircraft training is used to practice recovery from full upset conditions, including effects of startle and disorientation.…”

Loss of control is the largest contributor to the yearly aviation death toll, with energy mismanagement in low-energy conditions as one of its main causal factors. This has led to a large emphasis from both scientific and aviation safety communities on the prevention of aircraft upset conditions. Changes in aircraft configuration largely impact performance, and improved insight therein should allow pilots to better predict potentially dangerous situations, maintain suitable safety margins and more effectively react to unforeseen events. This paper presents the design and experimental evaluation of a Vertical Situation Display (VSD) with enhancements visualizing changes in the flight performance envelope. Sixteen pilots were tasked to fly approach and go-around scenarios with both a baseline and an ecological VSD, some of the scenarios containing flight control failures. Results show that the new display makes pilots maintain larger margins in velocity, thus spending less time below the advised minimum speed limit in final approach. However, these larger velocity margins also led to larger errors with respect to target velocities. Flight control failures were more often and more quickly discovered, and pilots reported feeling better able to predict dangerous situations. No significant differences in workload were recorded. These results conclude that the new VSD design enhances safety performance, but simultaneously raise the question whether the effect of enlarged safety margins is desirable if it causes a reduction in velocity tracking.

Aircraft loss of control is one of the largest contributors to fatal accidents in the aviation environment. The unprecedented change in aircraft dynamics due to loss of control onset and the associated structural constraints make loss of control prevention and/or recovery a challenging task. State-of-the-art autopilots are generally designed for nominal aircraft operations and disengage under off-nominal conditions, hence cannot be viewed as a safety solution during loss of control onsets. Herein lies the importance of providing training to pilots so as to equip themselves to rescue aircraft from loss of control events. Current pilot training methodologies have significant limitations when it comes to loss of control prevention and recovery strategies. In this context, a simulator for improved pilot training based on bifurcation and continuation techniques is presented in the paper. Augmenting these techniques with the current pilot training procedure can significantly improve the quality of training. This methodology can help pilots to distinguish various loss of control scenarios and aid them in taking appropriate recovery decisions intuitively. Meanwhile, a robust control-based loss of control handling module is also presented for developing non-intuitive strategies for loss of control prevention and recovery. This module can simulate adequate control profiles that the pilot can follow to get in and out of various loss of control scenarios. Moreover, it can be used as pilot activated recovery system in case of pilot disorientation and as a fully autonomous recovery system for much complex scenarios. The simulator is developed in MATLAB/SIMULINK platform and is shown to realize diverse loss of control events like spiral, spin, etc., and subsequent recovery from the same.
