Phrase Recognition Display and Transmission History

Phrase Recognition Display The Phrase Recognition Display area shows the most recent phrase recognised by the speech system. This feature is useful for determining the quality of the speech recognition. If desired for training purposes (such as to promote proper aural checking of readbacks), this area may be removed from the screen by changing the setting in the Setup Window.

Clicking on the down-arrow will display the previously-recognised phrases in time order. This may be useful when using the backstep function.

For some special exercises, this area is also used to convey performance information. For example, in Compromised Separation training, the Closest Point of Approach (CPoA) information is displayed here after each scenario.

    Radio Call Light

    Radio Call Light: Inactive

    The Radio Call Light provides an indication that a transmission is in progress, either by you, as the controller , or from an aircraft.

    If the call light is green, it is an indication that the frequency is not in use.

    Radio Call Light: PTT

    If the Call Light is yellow, your radio frequency is active. The button will display PTT for Press To Talk) when the controller is making a transmission. If the button is blank, or contains a decimal frequency number, this means that an aircraft is transmitting on that frequency.

    Range Display and Entry

    Range Display and Entry

    The Range Display and Entry textbox will show the current scale on the main radar display. This is the number of nautical miles (or kilometres for metric exercises) from the centre to the top of the display.

    A custom scale may be manually entered here. This must be between a lower and upper range limit which varies depending on the ATC sector under control. Typically, the allowable range is between 2 and 500 NM. If an range is entered outside these limits, then an error message will appear.

    Moving and Resizing the Map

    Commonly used functions in scrolling and resizing the radar screen are listed in the table below:

    Key

    Action

    Arrow Keys

    Offset map

    Page Up

    Decrease range

    Page Down

    Increase range

    Home or F9

    Restore default centre and range

    Shift-End or Shift-F10

    Store custom centre and range

    End or F10

    Restore custom centre and range

    The main simulator map is set to a default centre and range. To scroll to a new centre, the keyboard arrow keys may be used. The Page Up and Page Down keys are used to re-scale the map to a new range. Pressing Home or F9 will restore the map to the default centre and range. Pressing Shift-End or Shift-F10 will store the current centre and range as a custom setting. Pressing Endor F10 will revert to the custom centre and range. When the mouse is placed over the second radar screen, the use of the above keys will independently change the range and centre of the second radar screen. If the Mouse Zoom function is enabled, the centre and range of the map may be changed directly with a right click of the mouse

    Alignment

    The radar map is always aligned with either True or Magnetic North. The size of some large Enroute sectors with variable magnetic variation requires the radar map to be aligned to True North.

    In this version of the VV Simulator the magnetic variation is always zero, so this setting will not have an effect on the alignment of the simulator map.

    Map Colours

    Map colours are specific to each type of radar system. They may be changed in the Setup Window. After you have changed the colour palette, it may be stored as a personal setting. However every simulator update will require these settings to be re-recorded. It is recommended that the default colours be used.

    Aircraft Display

    Elements of Track and Label

    Aircraft on the main radar screen are presented in the form of a Radar Track with an associated data block or label. An aircraft’s display contains several elements:

  • The Radar Track or Symbol: In VV Enroute, this is presented as a round symbol, centred at the geographic location of the aircraft at the last radar sweep.
  • The Leader-Line: A line joining the radar track to the data block.
  • The Data Block (label): A block of text containing information pertaining to the aircraft.
  • History Dots: A set of markers showing previous positions of the aircraft. As the name suggests, these are records of where the aircraft was at the most recent radar sweeps.
  • Speed Probe: A line segment showing predicted future positions of an aircraft at one-minute intervals. The Speed Probes are an instantaneous indication of the aircraft’s direction and speed and are useful in predicting future conflicts and timing turn instructions.
  • Selection Indication: An indicator associated with the radar track showing that the aircraft has been selected for some action. In the VV system, the radar track is surrounded by a larger circle.
  • The elements of the radar track provide information to the controller about the direction of flight, level, speed and clearance information. Clicking on various parts of the label will allow changes to various aspects of flight data, or enable the controller to seek further information about the aircraft's disposition.

    Label Colours

    The colour of an aircraft’s display is determined by its control status. Aircraft that are under your control will generally have a different colour to those that are in a handover state (in out) or that are not yet under your control. Details are contained in the individual sector modules. For the VV system, controlled labels are green in colour, those that are handing-in or out are orange, and pending aircraft are blue. A particular aircraft display may be toggled between normal and a highlighted colour (quicklooked) by centre-clicking the radar track. Different elements of the label may also be presented in a different colour depending on the information presented to the controller. An example of this is the Cleared Level (CL/CFL) element which may be in highlighted color. Centre-clicking this element will toggle the highlight.

    Moving the Label

    It is important that the label be located so that information from it is not obscured by other labels. For this reason, controllers often adopt a technique of continually moving the labels as aircraft proceed. This also aids in maintaining situational awareness.

    The data block is rotated or relocated on the screen by right-clicking on the radar track symbol and dragging the label to the desired location while the right mouse button is depressed.

    Some systems use a process whereby label movement is completed in a two step process. The radar track symbol is right clicked to produce a frame. This is moved to the desired location and another right click will complete the process. The use of the mode is available by selecting Label Frame in the Setup Window.

    Some radar systems allow for automatic de-confliction of labels so that the system continually ensures that they do not overlap. Where available, this feature is selectable in the Setup Window.
