Create a Traffic Pattern with Traffic GroupsCreate a Traffic Pattern with Traffic Groups
City Pairs
EGLL
ENGM
Traffic Groups:Each defines a set of City Pairs between which there is air traffic, i.e. representing traffic in a region
CFMU data has been used as a basis for Traffic Groups
Flow Rates
Traffic Group - Configuration (1)Traffic Group - Configuration (1)
Traffic Group Outbound Flow, i.e. 32 flights, during hour 9 of a day.
City PairsThe proportion of flights between EGLL and ENGM amongst all flights into or out of EGLL in the Traffic Group
Aircraft Types
Traffic Group - Configuration (2)Traffic Group - Configuration (2)
Callsigns
The proportion of SAS callsignsamongst the other callsigns in the Traffic Group
The proportion of Boeing 737-800samongst all other aircraft types in the Traffic Group

Flight DetailsSimulation Time
Once traffic sample has been generated flights can be viewed, showing their route and timings

Aircraft Locations
The overall traffic situation at a point in time can also be viewed
Same Pattern / Multiple SamplesSame Pattern / Multiple Samples
Set a Random Number Stream
Random number streams are used to generate different traffic samplesfrom the same Traffic Pattern Description
Multiple Random SamplesMultiple Random Samples
Random Stream = 1 Random Stream = 10
Both samples are from the same Traffic Pattern Description at the same Simulation Time butwere generated using different Random Streams
Other Scenarios - e.g. Larger Airspace AreaOther Scenarios - e.g. Larger Airspace Area
Simulation Area
Large areas of airspace can be defined
Other Scenarios - ExampleOther Scenarios - Example

And traffic generated for a selected simulation area
