Abstract:

This report documents work performed by SRI International for the Federal Aviation Administration to study the potential cost-effectiveness of implementing Electronic Tabular Display Subsystems ETABS in the en route air traffic control system. ETABS is a device to electronically present flight data to air traffic controllers, and would automate certain control tasks. Cost comparisons are made for National Airspace System NAS Stage A system operations both with and without ETABS. Included for both operational systems are estimates of the present value of FAA expenditures during the fiscal years 1977 through 1999 for staffing, engineering and development, facilities and equipment, maintenance, and training costs relating to delay, accidents, and the like are not included. Staffing costs, which account for the major portion of the total expenditures examined, represent wage costs for Air Traffic Service controller and support personnel and for Airway Facility Service personnel. Controller staffing includes full performance level and developmental personnel, with allowances for advance recruitment needs. Computerized modeling techniques used to estimate staffing include the Relative Capacity Estimating Process RECEP Air Traffic Flow ATF network simulation, and Controller Advance Recruitment CAR routines. Results find that ETABS deployment would obtain cost savings relative to continuation of the current NAS Stage A system. ETABS cost avoidances are shown to result from various sensitivity analyses of the costs estimation procedures. Author
