Impact of operational factors on risk considerations of airplanes at high speed exits

Abstract

This study develops a lateral deviation based framework for identifying potential veer off risks at different turn off speeds, locations and turn off configurations of high speed exits. With introduction of newer air navigation technologies and reductions in in-trail separation standards, Runway Occupancy Times (ROT) of landing airplanes will become a critical capacity determinant in the future. Hence, High speed exits can be located instead of conventional 90 degree exits in view of reducing the ROT. Most critical operational factors friction coefficient and turn off speed are identified and ranked based on veer off probabilities and elasticity findings of operational factors. The developed framework including elasticity findings is beneficial at decision making on high speed exit locations, exit configurations in addition to extreme operational conditions. In response to the emerging demand on air transport industry, existing airport facilities must be expanded. Yet, limitations in land acquisitions result exploration of capacity improvement options using existing resources.
