Turbulence Control

The Turbulence GroupBox controls general atmospheric turbulence. The turbulence can vary from airport to airport, as defined by the weather areas in the Sortie File.

The Intensity ComboBox allows the selection of the strength of the turbulence from zero to 100%.

The Enable button begins or ends the selected turbulence immediately.

Note: If the Weather Mode is set to "Automatic" on the Weather Control Page, the Sortie File may enable or disable turbulence automatically. So, even though the turbulence parameters are set manually, they may change automatically by the Sortie File. If this behavior is not desired, it is necessary to set the Weather Mode control to "Manual".

Microburst Control

The Microburst Model controls the chosen microburst scenario. The named scenarios, such as "Denver", only refer to the wind profiles in those models; they do not reposition the simulated aircraft to that named airport. The available scenarios include:

1. Kennedy 1975


2. New Orleans Takeoff


3. Generic Headwind and Crosswind


4. Denver 1984 / Tucson 1977


5. JAWS Course


6. Dallas / Fort Worth (DFW)

The DFW microburst is special in that it may be repositioned to several points on the airport, as described below. The other microburst models are not repositionable, but rather occur at predetermined places on the airport.

The Intensity ComboBox allows the selection of the relative strength of the chosen microburst, from zero to 200% of the usual value.

The Microburst Position control sets the relative position of the microburst on the airport for the DFW microburst model only. There are five locations for the microburst on the landing end of the runway, and three possible locations for the microburst on the departure end of the runway.

The Microburst Enable button arms or deactivates the chosen microburst scenario. The scenario is triggered when the simulated aircraft reaches a specific point on the airport.

Note: The microburst scenario applies to any airport, and there is only one microburst scenario available at any time. In other words, the Sortie File does not set up individual microburst scenarios for individual airports.

Windshear Control

The Windshear GroupBox controls the parameters for windshear training scenarios.

The Windshear Model ComboBox allows the selection of the specific windshear model to be used in training. The named scenarios, such as "Kennedy", only refer to the wind profiles in those models; they do not reposition the simulated aircraft to that named airport. Possible selections are:

1. Generic windshear on takeoff - moderate intensity


2. Generic windshear on landing - moderate intensity


3. Generic windshear on takeoff - severe intensity


4. Generic windshear on landing - severe intensity


5. Tokyo windshear scenario - moderate intensity


6. Logan windshear scenario - moderate intensity


7. Philadelphia windshear scenario - severe intensity


8. Kennedy windshear scenario - severe intensity

The Intensity ComboBox is used to select the relative strength of the chosen windshear model. The normal model intensity is 100%. However, the intensity can be varied from zero to 200% of the normal value.

The Enable button, when depressed, allows the windshear scenario to begin when the aircraft reaches a predetermined point with respect to the active airport. Similarly, the windshear scenario can be cancelled by selecting this button again.

Note: The Windshear models are "global" models, in that they are not associated with a specific weather area, as loaded by the Sortie File. In other words, only one windshear scenario can be set up per Sortie File; not a separate scenario per sortie.
