For each month, and the prior 11 months (i.e. use a 12 - month calculation), calculate the percent that oceanic air traffic compri ses of total domestic air traffic and multiply that percentage by 3. Multiply that modified percent figure by the average weighted hourly count derived in (H). This will yield the oceanic add - on count. (Example: The ocean traffic count equals 10% of the to tal domestic traffic count; the average weighted hourly count (H) = 500). The formula is: (.10 x 3 = .30 x 500 = 150) M. For each day and the prior 364 days (i.e. use a 365 - day count): 1. Divide the facility's airspace by 10,000 square miles. 2. Calculate the d ensity add - on (average weighted hourly count (H) /density (1. above) x 1.5). Example: 1. 103,440/10,000 = 10.344 2. 500/10.344 = 48.337 3. 48.337 x 1.5 = 72.5 or (73) N. For each day and the prior 364 days (i.e. use a 365 - day count): 1. Calculate the total flight t ime in minutes for all aircraft in the center's airspace for the average hour of the 1830 busiest hours; 2. Determine the average hourly sector operations (i.e. the total of all flights penetrating all sectors in the center for the average hour of the 1830 b usiest hours); 3. Divide the total flight time in minutes (1. above) by the average hourly sector operations (2. above) x 3 to obtain the airspace usage add - on. Example: 1. 10615 2. 1069 3. 10615 / 1069 x 3 = 29.8 (or 30) O. Each facility: 1. An en route facility is credited with having mountainous terrain if it has land depicted as "mountainous terrain" as specified in FAR 95 Subpart B and, has terrain above 10,000 feet MSL within the facility's designated airspace = 5%; 2. a) If it interacts with one (1) foreign count ry = 1%;
