An Evaluation of Personal Computer-Based Aviation Flight Instruction
… was found on introductory instrument flight maneuvers. There was a significant airplane flight time savings to final certification in the experimental group. In all cases, there was positive correlation between student's and instructor's attitudes towards the use of the PCATD, and it …

Autonomous altitude estimation of a miniature helicopter using a single onboard camera.
… (UAV) is extremely important when dealing with flight maneuvers like landing, steady flight, etc. Vision based techniques for solving this problem have been underutilized. In this thesis, we propose a new algorithm to estimate the altitude of a UAV from top-down aerial images taken from a single …

Acoustic theory of sonic boom propagation in an inhomogeneous atmosphere
… waves produced by an aircraft in supersonic flight through an atmosphere in which the speed of sound decreases linearly with altitude. The problem is first studied in terms of the geometry of the rays along which the shock wave travels away from its point of origin and into the surrounding …

Adaptive Control of Nonaffine Systems with Applications to Flight Control
Traditional flight control design is based on linearization of the equations of motion around a set of trim points and scheduling gains of linear (optimal) controllers around each of these points to meet performance specifications. For high angle of attack maneuvers and other aggressive flight …

Adaptive output-feedback control and applications to Very Flexible Aircraft
… (VFA) corresponds to an aerial platform whose flight dynamics critically depends on its flexible wing shape, and has been investigated as a potential solution to generate high-altitude low-endurance flights. The dominant presence of model uncertainties and potential actuator anomalies motivate …

Comparison of Voice and Text ATC Communications in the Cockpit for ESL Pilots
<p>Throughout the course of any flight, pilots and air traffic control (ATC) are in constant radio communication regarding the position and route of the aircraft. Effective pilot-ATC communication helps to increase safety by increasing the situation awareness of both the pilot and controller. In …

A three-dimensional turbine engine analysis compressor code (TEACC) for steady-state inlet distortion
… military aircraft are subjected to rapid flight maneuvers which place great operational demands on their compression system by producing highly distorted flow to the compressor. Inlet distortion generally reduces the engine compressor stability margin and may induce compressor surge at …

Trajectory optimization and data-driven modeling for robotic bat flapping flight
Planning flight trajectories is essential for practical application of flying systems. This topic has been well studied for fixed and rotary winged aerial vehicles, but far fewer works have explored it for flapping systems. Trajectory planning requires a model that is both accurate and …

Analysis of High Angle of Attack Maneuvers to Enhance Understanding of the Aerodynamics of Perching
… vastly unsteady aerodynamics, mimicking the flight maneuvers of natural flyers requires a deep understanding of the unsteady flow physics while also demanding the ability to expand the vehicle's flight envelope beyond normal conditions. Experimental and computational investigations are …
