Departure and Regulation Delays

Function presentation

This function displays the Delays figures for a Departure Aerodrome or a Regulation associated to a selected date and time period.

Opening the window

From the Application / ATFCM menu, select the option Traffic / Delays.
Immediate shortcut to bypass menu selection : <Ctrl> + <Shift> + <F8>.

A new empty Delays window will be opened with the following defaults :

Traffic Date : current or last queried traffic date is proposed (relative to current UTC date) depending on selected user preference (CHMI / ATFCM application / General / Dates and times / Default date proposed for query).
WEF time : proposed based on the Default query period assignment using your user adjustable preferences.
UNT time : proposed based on the displayed WEF and the Default query period assignment.
Where : last element used with this query This selection is based on the system property CHMI / ATFCM application / Traffic / Traffic delays / Last Used Reference Location Type.
Is : based on the "Where" selection, the drop-down box will propose the most recent query data elements you have queried before with success.

The Where parameter can be :

Regulation,
Departure Aerodrome.

On initial display, the focus is set on the first mandatory query control with no default value: the Is input control.

Preparing to query

The observed period may be adjusted as follow :

The traffic Date may be adjusted to one of the proposed values. Common ATFCM Tactical / Pre-Tactical dates behaviour is implemented.
The proposed default WEF and UNT times may be overwritten.
Any valid time value from 00:00 to 23:59 included may be entered in the WEF and/or the UNT entry boxes. This input must respect the HH:MM format.
Drop-down list may be used to select pre-formatted time on a 20 minutes step base.

The period resulting from the input will be validated taking into account the system property CHMI / ATFCM application / General / Dates and times / Query over midnight.
If query over two days is not authorised, the WEF time must be smaller than the UNT time, except if both times are set to 00:00, which corresponds to a full day query.
The Default query period assignment will be used.
The Where parameter may be adjusted to one of the following values :

Regulation.
Departure Aerodrome.

The identifier corresponding to the selected Where shall be keyed in the associated Is entry box or selected from the drop-down list (when a previous query was successful).
Select the Proposal radio button on the button bar to include the proposed flights in the delays figures. Otherwise the figures 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.

Displaying the query results

Common Display

The window title contains the following information :

The selected Departure Aerodrome or Regulation identifier.
The time stamp when the information was retrieved from the CFMU system.
The optional keyword (Prop) indicates that the displayed data are including the flight "Proposals".
The optional keyword (Poll) indicates that the Polling function is active for this window.
The optional >> sign indicates that the covered time period will shift on refresh.

The header box contains the selected query criteria :

The observed period (Traffic date, WEF and UNT times).
The main Where selection criteria (Departure Aerodrome or Regulation).
The identifier associated to the selected Where.

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.
Underneath the split bar that separates the Query fields from the query results there are two data presentation buttons; they allow the user to select one of the following display types:

Graph : bar chart representation of the delay figures.
Table : tabular presentation of the different delay figures.

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 or the Table, depending on the selected type.
The first bar of the Graph or the first cell of the Table is then selected.

Graph display

Underneath the splitter bar and when the graph is displayed, a drop-down menu is available from which the user can choose to display another category of delay figures.
These categories are either the amount of delay in minutes for :

Delayed Traffic average delay
Delayed Traffic maximum delay
Delayed Traffic total delay

or the number of flights that are impacted.

CASA Regulated Traffic Demand
Delayed Traffic Load

The counts are made every 20 minutes. The value associated is always an hourly value (e.g. 12 flights delayed between 11h20 and 12h20).
Each bar on the graph represents an hourly count for a time slice of the selected delay category.
The colour of the delay bars is identified by the user adjustable preference CHMI / ATFCM application / General / Graph / Bar default colour.
The vertical axis indicates either the number of flights per hour or the number of minutes per hour.
The horizontal axis indicates the time periods.

Table display

The tabular representation provides :

The different time slices covered by the delays query.
The Traffic Delay values for the different categories.

These delay values are either in minutes for :

Delayed Traffic average delay (av. delay).
Delayed Traffic maximum delay (Maximum delay).
Delayed Traffic total delay (Total delay).

Or in number of impacted flights for :

CASA Regulated Traffic Demand (Reg. Traf. Dem.).
Delayed Traffic Load (Delayed Traf.).
