2016 CBA Tentati ve Agreement Page 165 of 217 G. Each VFR arrival or VFR departure count at secondary airports or V FR overflight is given a weight of 1.00. H. Each IFR/SVFR overflight count is given a weight of 1.25. I. The hourly counts for all operations (D) through (H) are added together to obtain the average weighted hourly count. J. For each day and the prior 364 days ( i.e., use a 365 - day count), calculate the percent that military air traffic comprises of total air traffic. Divide that percent figure by four, and then multiply by the average weighted hourly count derived in (I). This will yield the military add - on count (J). (Example: The military traffic count equals 20% of the total traffic count; the average weighted hourly count (I) = 100). The formula is: (.2 / 4 = .05 x 100 = 5) Note: The military mix calculations shall be based on automated capabilities; however , where automated capabilities are not available the most recent yearly APO/OPSNET data shall be used. K. For each day and the prior 364 days (i.e., use a 365 - day count) calculate: 1. The percent of total Approach Control traffic that is: a. air carrier and mili tary traffic combined b. general aviation traffic c. air taxi traffic Note: The aircraft mix calculations shall be based on automated capabilities; however, where automated capabilities are not available the most recent yearly APO/OPSNET data shall be used. 2. Determine which of the two (i.e. air carrier and military traffic combined or general aviation traffic) constitutes a lower percentage of the total traffic. 3. Add the air taxi traffic to the lower of the two, (i.e. air carrier and military traffic combined or general aviation traffic). 4. After adding the air taxi traffic to either the air carrier and military traffic combined or general aviation traffic, calculate the percent traffic mix of the two categories of traffic (i.e., the one including air taxi and t he one excluding air taxi). 5. Take the lower percentage of the two figures derived in (4) above and divide it by four, then multiply by the average weighted hourly count derived in (I). This will yield the traffic mix add - on count. Example: 1. air carrier an d military traffic combined = 58% 2. general aviation traffic = 32%
