Comprehensive Approach to Pilot Disorientation Countermeasures
Published in Michael A. Vidulich, Pamela S. Tsang, Improving Aviation Performance through Applying Engineering Psychology, 2019
Extreme flight maneuvers usually combine some basic aerobatic maneuvers such as an aileron roll, where the aircraft is rolled 360 degrees around its longitudinal axis (stimulating primarily the posterior semicircular canals), and loop, which is a 360-degree turn in the vertical plane (stimulating primarily the anterior semicircular canals). The Cuban Eight is a maneuver that combines portions of the loop and roll. The entry requires a high G pull (> +3 Gz) until the aircraft approaches vertical, as the aircraft reaches the inverted position, a half roll flown as a point roll (zero G) is commenced to avoid barreling off the reference point. Other extreme flight maneuvers such as the Immelmann turn and Split-S maneuver all require pitch maneuvers with high G pull up followed by roll maneuvers that would stimulate primarily the anterior and posterior canals respectively. For example, the Immelmann turn requires an ascending high G pull half-loop (stimulating primarily the anterior semicircular canals) that finishes with a half-roll out (stimulating primarily the posterior semicircular canals), resulting in level flight in the exact opposite direction at a higher altitude. Similarly, the Split-S maneuver, also called a reversed Immelmann turn, requires rolling inverted (stimulating primarily the posterior semicircular canals) and finishes with a descending loop (anterior semicircular canals stimulation) to wings level at a lower altitude.

The Type-6 Primary Trainer is an aircraft designed and built in China, with a nose wheel and two seats, meant to conduct simulated flight training for flight cadets or other flight enthusiasts as a basic trainer. This simulator can simulate a variety of flight subjects, e.g., traffic pattern flight, daylight instrument flight, night instrument flight, formation flight, aerobatic flight, etc. This study was performed using the simulator of the Type-6 Primary Trainer. Due to limitations in the training time, the traffic pattern flight was chosen for the main training subject. This refers to the aircraft flying around the airport according to the scheduled flight route and strictly maintaining the specified altitude and speed. It is the foundation of all flight activities. Procedures of traffic pattern flight include taxiing along the runway, takeoff, lift-off and climbing, level flight, landing, etc.
Unmanned aerial vehicles using machine learning for autonomous flight; state-of-the-art
Published in Advanced Robotics, 2019
Punjani and Abbeel [66] introduced Rectified Linear Unit (ReLU) Network Model for aerobatic maneuver of the helicopter, providing details about parameter initialization and optimization methods. The aerobatic helicopter is known as difficult to both model and control due to its complex maneuvers, and it has only been successfully flown under autonomous control using apprenticeship learning, which leverages expert demonstrations to efficiently learn good controllers for tasks being demonstrated by an expert [67]. They utilized real-world data collected by an expert pilot from the Stanford Autonomous Helicopter Project. They demonstrated that the ReLU Network Model improved RMS acceleration prediction by 58% over prior state-of-the-art for dynamics modeling of the aerobatic helicopter even though this model didn't enable autonomous control of the helicopter through aerobatic maneuvers.
High G flight: physiological effects and countermeasures
Published in Ergonomics, 2018
In this book the author, a highly experienced aeromedical scientist and qualified fast jet pilot, aims for the first time to bring together the scientific literature on human exposure to high G environments. It is somewhat surprising that this has not been done, but as the author points out, the importance of high G is usually limited to the demands of combat fast jets, civilian aerobatic aircraft and spacecraft. From this perspective, the book is a very useful addition for human factors specialists working in these domains; breaking the key theoretical and practical elements in to clear and insightful sections that can be applied in practice, as is the books aim.
