Following Count Types may be available depending on the selected Where
criteria :
Entry counts are available for all possible Where entries.
Occupancy Type is only available for Airspace, Traffic Volume based on an
Airspace and Aircraft Operator.
In the case of Occupancy Type, the returned counts contains :
The different Traffic Types can be checked or unchecked :
Duration is only available when Occupancy
Type is selected:
Any combination of these Traffic Types may be requested.
At least one Traffic Type must be checked on issuing the query.
Select the Proposal radio button on
the button bar to include the proposed flights in the retrieved counts.
Otherwise the counts will be based on the normal flights only.
The Send button will send the query to
the CFMU system.
This window may be closed before any query is issued.
The Reset action common functionality
is implemented for this function. All query criteria except Normal/Proposal
selection are considered for activating the Reset action.
The window title contains the
following information :
The header box contains the selected query criteria :
A split bar separates the query fields from the query results. It includes on
the left, a small arrow button (Up/Down) to Hide/Show the query part.
The query part may be hidden automatically on displaying the query results,
depending on the user adjustable preference CHMI / ATFCM application /
Traffic / Traffic counts / Hide query on reply.
Underneath the split bar that separates the query fields from the query results
there are three data presentation buttons; they allow the user to select one of
the following display types:
The Graph display is shown initially.
When the user chooses to change the display type then the active window will
use the data previously retrieved.
When the query results are displayed, the focus is set on the Graph, the Table
or the Regulation list, depending on the selected type.
The first bar of the Graph, the first cell of the Table or the first line of
the list is then selected.
On the top of the graph, a
group of three toggle buttons allows to select the traffic type(s) to be
included in the graph :
Each button is activated when the corresponding Traffic type has been
successfully retrieved from the CFMU systems.
All retrieved Traffic types are displayed initially.
Each traffic type is rendered differently on the graph. From the first Traffic
Type displayed to the last, the brightness of the different colour used is
reduced. This is done to ease the recognition of each bar based on the Traffic
Type.
The graph contains a series of vertical bars representing the number of flights
according to the count Type requested.
Each vertical bar is composed of a series of stacked coloured blocs
representing the following flight sub-totals:
The above sequence is used by default from bottom to the top of the bar.
Some of these blocs might be absent if the corresponding sub-total is 0.
Dedicated user preferences may be adjusted for the piling up sequence (CHMI
/ ATFCM application / Traffic / Traffic counts / Count piling up order) and
the colour associated to each sub-total (i.e. CHMI / ATFCM application /
Traffic / Traffic counts / Suspended count colour).
The count value represents the number of
flights over the next 20 or 60 minutes for Entry counts or at the beginning of
each minute for Occupancy counts depending on the count Type selected
during query preparation.
The count value is shown every 20 or 60 minutes for Entry counts or every 1
minute for Occupancy counts depending on the initial choice made during the
query preparation.
The capacity value is drawn as line on the graph, if 60 minutes counts have
been requested.
To avoid confusion, hourly capacity is not shown on the graph when 20 minutes
counts are displayed.
The colour of the capacity line is identified by the user adjustable preference
CHMI / ATFCM application / General / Graph / Capacity colour.
Below the graph,
On the graph itself, a thin line shows the period when a regulation is active
and the corresponding flight rate. The colour of this line is identified by the
user adjustable preference CHMI / CHMI / ATFCM application / General / Graph
/ Regulation colour.
The vertical axis indicates the number of flights.
The horizontal axis indicates the time periods.
The tabular representation provides
:
Following break down is given for the count values :
These count categories are listed in following sequence :
A counter identifies the number of
Regulation entries.
The main listbox of the window shows the list of Regulations affecting the
selected count data.

are applicable.
Each detailed Regulation line contains :
The Normal / Proposal button may be
