This report evaluates, in simulation, the procedural implications of the Vortex Advisory System (VAS) on the Chicago O'Hare terminal air traffic control environment. It also attempts to demonstrate any cost benefits/capacity gains which may accrue using reduced VAS aircraft separation criteria on the final approach course based upon meteorological assurance of vortex dissipation. Utilizing the National Aviation Facilities Experimental Center (NAFEC) Digital Simulation Facility (DSF), a real-time simulation of the Chicago O'Hare International Airport airside operations was conducted between March 28 and June 24, 1977. There were 105 data runs of 1 hour and 20 minutes duration completed during this period. Test results indicate that (1) no procedural implications emerged which would deter the implementation of VAS at Chicago O'Hare Airport, and (2) arrival rate increases are sufficient to support previous cost/benefit analysis studies.
