Any of these events may contribute to excessive noise. Without understanding a cause and effect relationship between these events and the noise created, it may be difficult to reduce noise around an airport. Answers to these and many other similar questions are often based on a combination of many factors.

Airport Operations may be an underlying cause of noise problems, as operations on the ground may force a pilot to alter his approach in a manner which may violate noise reduction edicts. Another factor to consider is airport weather conditions. These conditions may include: Wind speed, directions, gusting; Wind shear alert; Visibility; Precipitation; Snow; Runway conditions, standing water, ice, and the like; Cloud ceiling; Temperature; and Dew point. In the Prior Art, all of this data was not available.

Correlating aircraft flight tracks, noise data, and other related aircraft, airport, and environmental data, would require difficult and time-consuming manual labor. Making the connection between conditions on the ground, for example, and a noise event may have proved difficult. Prior Art noise monitoring systems could do little other than determine which aircraft are in violation of noise rules—without determining the underlying causes of the noise violations.

What remains a requirement in the art, therefore, is a system which can acquire and store all types of aircraft, airport, and environmental data, as well as aircraft tracking and noise data, and allow a user to correlate or filter such data to discover trends between different data scenarios. And thus a requirement remains in the art for a system that not only tracks aircraft flight, departure, and arrival patterns, but also a system which can provide information as to why such patterns occur.

Therefore, answers may be available to the question noted above. The Aircraft performed a go-around until both ceiling and visibility requirements were met. Otherwise the aircraft would have re-directed to another airport. The answers to these questions may allow airport operators, planners, pilots, and airline operators to better manage airport, airline, and airplane operations so as to reduce instances of noise violations and better manage airport operations.

Having ongoing automated access to data on airport operations, airport weather, ATC instructions, and aircraft equipage allows airport management to understand why certain operations are happening and causing complaints, not just to observe the effects.

Other systems provide only the flight track, noise event and complaint data, and a manual recording of various ATC frequencies. Therefore other approaches do not offer any type of automated correlation of operational information with noise and flight track data. For example, using this unique fusion process it is possible to run the following query combinations as illustrated in FIG.

The resultant data may be compared to periods when there was not ongoing construction to determine whether certain construction were causing noise complaints. If this was the case the airport may look to see, for example, if Air Traffic Control ATC had changed arrival procedures to runway 23L as a result of the construction. In the example of FIG. Aircraft flight track data, as well as noise data may be acquired using any one of the number of techniques disclosed in the co-pending and issued Patents to Rannoch Corporation cited above.

These other sources may provide data in a number of formats, either electronically, or they may be manually entered. Examples of such data sources are described as follows. The present invention is not limited to these data sources, but may also include other data sources within the spirit and scope of the present invention.

ATIS comprises recorded information, which is broadcast continuously over designated frequencies. The air traffic control tower prepares this information to provide arriving and departing traffic information pertaining to active runways, weather conditions and notices to airmen NOTAMS.

This will also be cummulative with the scale applied if the scaleDelta option is greater than 0. Float Yes scaleDelta This attribute will add a random variation in scale to each model placed along the vector path. The default value is 0, which is no random variation, and any value greater than 0 will be used to apply a random variation in size to each model using the given value as a magnitude for the variation.

This variation will be cumulative with the scale setting. Float Yes rotation With this attribute you can change the way the model rotation will be handled by the simulation. It can be one of the following strings: "Follow edge": The models will be orientated relative to the direction of the vector path it follows "Same": All the models will be orientated in the same, single direction, which can be edited using the Model Headings parameter below.

String Yes avoidDiscontinuity This attribute can be set to "TRUE" to have the scenery editor try and ensure that the models used match up correctly at the corners of the vector path.
