One example is Precision Runway Monitor (PRM). This is a high update radar system installed at ATL, which allows simultaneous instrument approaches to parallel runways as close as 3000 feet apart (Federal Aviation Administration, 2014). Noted by the FAA, another improvement in use at is Same Runway Departure Fanning that uses Equivalent Lateral Spacing Operations (ELSO). This improvement allows reduced separation between successive departures due to the availability of new Standard Instrument Departure (SID) procedures, which provide more precise guidance and control for departing aircraft. Lastly, ATL has developed four weather conditions, modeled due to distinct operational differences between Instrument and Low Instrument conditions. Visual, marginal, instrument, and low instrument conditions divided into departure and arrival priority modes are heavily used during unbalanced periods of activity on the field. Reference Figure 3 for a description and annual observations of each condition and Figure 4 for the expectation of hourly operations in each
