A report on the economic effects of air traffic congestion shows that both excessive operating costs, resulting from growth in block times, and aircraft utilization losses resulting from unproductive operating hours have contributed to the total cost of air traffic delays. Three principle items are identified in the computations. Ground waiting time, or out of time; the product of upproductive hours (time spent waiting in line to take off) multiplied by out-off cost per hour is the excess cost attributed to unproductive out-of-time. Airborne time was derived from equations that yielded the difference in minutes in flight time between early-morning Boeing 727 cargo flights and daytime passenger flights. The average difference in minutes in flight time between the early morning hours and congested times of day was computed and utilized in the derivation of unproductive airborne hours for each year. The computation of aircraft utilization loss is also detailed.
