Estimation of Runway Throughput with Reduced Wake Separation, Runway Optimization, and Runway Occupancy Time Consideration
This thesis estimates potential runway throughput gains using a reduced wake separation based on the 123 most prevalent aircraft in the United States fleet. The analysis considers Runway Occupancy Time (ROT) constraint factors and existing geometric design factors. This research extracts the …

Benefits of Additional Runway Crossings on Parallel Runway Operations
… the increasing traffic. Among these problems, runway crossings are a considerable source of ground traffic inefficiency and risk. Building end-around taxiways are the only strategy to avoid crossings, but these are not always feasible, and therefore airport planners must find alternatives. This …

The influence of runway occupancy time and wake vortex separation requirements on runway throughput
Air traffic growth in the U.S. has led to runway capacity constraints in the air transportation network. There has been limited new construction of runways due to land availability. One approach to increase capacity of existing runways is to reduce inter-arrival separations during the final …

An analysis of runway capacity
… interpreted. The system modeled includes the runway and its associated approach and departure path airspace, including a holding stack. As an example of how the simulator may be used: and its results interpreted, a regression analysis was performed on the simulator output in order to arrive at …

Runway Exit Speed Estimation Models
Increasing air traffic in the U.S.A has led to runway capacity limitations at the airports. Increasing the capacity of the existing runways involves reducing the runway occupancy time of an aircraft landing on a runway. The location of runway exits plays an important role in minimizing the runway …

Maximising runway capacity by mid-term prediction of runway configuration and aircraft sequencing using machine learning
Maximising runway capacity is one of the essential measures to meet the growing traffic demand. Runway capacity maximisation is an open challenge in the literature due to a complex and non-linear interplay of many factors which are stochastic in nature such as wind, weather, and arrival and …

Examination of Runway Occupancy Times for General Aviation Aircraft
… One metric able to measure usage is through runway occupancy time. This study looks at the impact on runway occupancy times from two independent factors. The first factor is the difference between Instrument Flight Rules (IFR) aircraft and Visual Flight Rules (VFR) aircraft. The second factor …
