Facility profile count (J) = 8.5 Modified average weighted hourly count (K) = 5 + 10.5 + 8.5 + 100 = 124 L. Calculate the TCI as described earlier under the section titled "Co mplexity Formula - Sustained Traffic Index." PART II – APPROACH CONTROL For each average hour of operation (i.e. the 1830 busiest hours divided by 1830): A. Each IFR/SVFR arrival, departure, or VFR practice instrument approach count at the primary airpor t is given a weight of 1.50. B. Each VFR arrival or departure count at the primary airport is given a weight of 1.00 C. The hourly counts for (A) and (B) are added together to obtain the combined arrival and departure count at the primary airport. D. This combin ed arrival and departure hourly count at the primary airport is then multiplied by a runway factor: 1. 1.15 if the airport has crossing runways. 2. 1.10 if the airport has converging runways. 3. 1.05 if the airport has a single runway, including parallel runways that are separated by 2500 feet or less. 4. 1.00 if the airport has parallel runways. (Note: If two or more configurations exist at one airport, the highest multiplier shall be used; if a runway is not in a commissioned status as defined in the Airport / F acilities Directory it should not be considered in determining runway configuration.) E. Each IFR/SVFR arrival, departure, or VFR practice instrument approach count at secondary airports fifteen (15) miles or less from the primary airport is given a weight o f 1.50. F. Each IFR/SVFR arrival, departure, or VFR practice instrument approach count at secondary airports more than fifteen (15) miles from the primary airport is given a weight of 1.25.
