Longitudinal Separation Analysis of the Central East Pacific Track System.
Abstract
This report represents an evaluation of aircraft mach number spacing and inertial navigation systems (INS) as regards their impact on longitudinal separation and collision risk in the Central East Pacific (CEP). A nomograph was produced for predicting maximum expected changes in longitudinal separation of aircraft flying with mach number spacing on long-distance transoceanic flights. Results indicate that a statistically significant difference in maintaining longitudinal separation exists between those aircraft employing mach number spacing techniques and those not using the techniques, and likewise between aircraft with more sophisticated air data systems than those without. Collision risk from loss of longitudinal separation was found to be at an acceptable level, both in the old and current CEP systems. (Author)
