Title of dissertation: Real Time Terminal Area Trajectory Planning For Runway Independent Aircraft Min Xue, Doctor of Philosophy 2006 Dissertation directed by: Assistant Professor Ella M. Atkins Department of Aerospace Engineering The increasing demand for commercial air transportation results in delays due to traffic queues that form bottlenecks along final approach and departure corridors. In...

This report examines a rollout and turnoff (ROTO) system for reducing the runway occupancy time for transport aircraft in low-visibility weather. Simulator runs were made to evaluate the system that includes a head-up display (HUD) to show the pilot a graphical overlay of the runway along with guidance and steering information to a chosen exit. Fourteen pilots (airline, corporate jet, and resea...

The development and application of most present-day systems and control theory were spurred on by the need to resolve aerospace problems. This is roughly the problem of analyzing and designing flight control systems for tactical missiles or aircraft. The control laws used in current tactical missile or aircraft are mainly based on classical control design techniques. These control laws were dev...

RATIONALE It was recently demonstrated that the priming stimulation effect (PSE) in the runway model of intracranial self-stimulation (ICSS) can be used as a model system to study the motivational effects of drugs. However, the characteristics of this novel experimental model have not been fully clarified. OBJECTIVE To elucidate the involvement of dopamine uptake inhibition in motivated behav...

Recent models of visual information processing suggest that visual attention can be focussed on either Head-Up Displays (HUD) or on the world beyond them, but not on both simultaneously. This hypothesis was tested in a part-task simulation in which subjects viewed a simulated approach to a runway with a HUD superimposed. An alphanumeric cue ("IFR" or "VFR") appeared on either the HUD or the run...

Abstract The runway and landing gear speed difference causes non-negligible friction at touchdown, generating vital heat to raise the tyre tread temperature. resulting material decomposition reduces thickness significantly impacts flight safety environment. Airline operators also need pay cost of frequent replacement. pre-rotation strategy has been proposed prevent high-speed touchdown. Therefo...

The aircraft anti-skid braking system (AABS) plays an important role in taking off, taxiing, and safe landing. In addition to the disturbances from complex runway environment, potential component faults, such as actuators can also reduce safety reliability of AABS. To meet increasing performance requirements AABS under fault disturbance conditions, a novel reconfiguration controller based on li...

The Runway Configuration Management problem governs what combinations of airport runways are in use at a given time for an airport or a collection of airports. Runway configurations (groupings of runways), operate under Runway Configuration Capacity Envelopes (RCCEs) which limit arrival and departure capacities. The RCCE identifies unique capacity constraints based on which runways are used for...

We analyzed a special-purpose dataset containing times at which flights crossed concentric circles at various distances from six major US airports in July 2001. We converted the circlecrossing information into effective speeds along four flight segments defined by the circles. Working with data in 15 minute intervals, we correlated the segment speeds with runway loading, defined as expected arr...

III Lincoln Laboratory has developed a prototype runway-status light system (RSLS), designed to prevent runway incursions and accidents. These status lights will tell aircraft pilots and surface-vehicle operators when runways are unsafe to enter or unsafe for departure. This status information will improve the situational awareness of pilots and vehicle operators, thereby reducing the number of...
