Traffic Patterns. Aircraft approaching a runway for landing usually follow a standard landing pattern. Most runways are positioned so planes will take off and land into the wind. In most cases, the pattern is a rectangular box with the pilot making all turns to the left, as shown in Figure 3.1. Pilot: Millville traffic. Cherokee two zero niner zero whiskey, entering left downwind runway one zero, Millville. In a few cases, airports will use right traffic patterns. However, don’t assume all aircraft will always be flying in the standard pattern - it is not required, only recommended - so keep a visual look out to the sky just FAA Guide to Ground Vehicle Operations Non-Towered Airports FAA Guide to Ground Vehicle Operations Non-Towered Airports in case a pilot decides to fly a ‘straight in’ approach and doesn’t enter the standard traffic pattern. Similarly, if a pilot announces "short final", expect that aircraft’s landing to be imminent. Pilots announce their position on the Common Traffic Advisory Frequency (CTAF)/Unicom using the names of the segments of the traffic pattern: Upwind, Crosswind, Downwind, Base and Final. See Figure 3.1 Extra vigilance is essential at non-towered airports, or when the control tower is not operating. While there may be CTAF or UNICOM frequencies available, pilots are not required to communicate or announce their position in the traffic pattern or on the surface. As a result, a driver can be lulled into complacency because the airport is not very busy. Nevertheless, always remain alert for the unexpected, even when aircraft traffic levels are light. Another factor involves the runway angle or slope, which makes it difficult or impossible to see the entire length of the runway. As a result, an aircraft can suddenly appear on a runway when you are crossing. Generally, it is good practice to cross runways at their ends.

Traffic Patterns. Residential broadband traffic patterns varies considerably in terms of usage and application types [70][75]. The IEEE 802.16 [80] accepted the ON/OFF wireless traffic model [81] as reliable for simulations of wireless networks. The model adopts superposition of various Poisson distributions to produce a batch Markovian arrival process (BMAP). Recent research [75] on residential traffic pattern indicates varying traffic load at different times of the day for Res and SME. If we assume that the residential users in figure 1 request their traffic content from the internet, then we can effectively model the popularity of accessing particular broadband service using Bimodal Xxxx; session arrivals using exponential for short time-scales, time-of-day and time-zone using correlated behaviour; and finally session durations using heavy-tailed [82].
