6.2.4 Aircraft Delay:
Delay is the increase in time required to operate “normal” non-delayed operations. Aircraft
delay exists because of local weather and operational conditions. Delay is measured in
minutes per aircraft and hours per year. The FAA's assumptions identified in
(AC150/5050- 5 , Airport Capacity and Delay ) are used to identify delay measures. It is
necessary to maintain the capacity of the airport greater than demand, to avoid delays.
The delay will be determined depending on the ratio of the forecasted annual operations to
annual service volume operations as shown in Table 6-3.Table 6 - 3Ratio of Annual Demand Operations to Service Operations.............................
