Suspended Flight List

Function presentation

This function lists all suspended flights based on the Traffic Demand for a combination of several query criteria.
The main query criteria includes a period and a reference location with related sub-criteria.
In addition, there are two optional criteria : an Aircraft Operator and a most penalizing FMP.

The flights are selected on :

Opening the window

From the Application / ATFCM menu, select the option Flights / Suspended Flight List.

A new empty Suspended Flight List window will be opened with the following defaults :


Current UTC time used is corrected with the Time adjustment user preference (CHMI / ATFCM application / General / Dates and times / Time adjustment).
Following non-modifiable query data elements are not displayed:
The system property Query over midnight which authorises to query over two days, may possibly limit this time calculation process to the start of the day (00:00) (CHMI / ATFCM application / General / Dates and times / Query over midnight).
When Traffic Volume is selected, the Flow control is proposed empty. The drop-down list is filled in with the most recent IDs you have queried before with success.
When Aerodrome or Aerodrome Set is selected, the related category controls (Cat) are proposed. Global button comes preselected.
When Point is selected, the Maximum (MAX) and Minimum (MNM) Flight Level (FL) controls are proposed. They are initialised with the extreme values (990 for MAX and 000 for MNM).
The FMP input box is proposed empty. The drop-down list is filled in with the most recent IDs you have queried before with success.
When Where is not set to Aircraft Operator, the secondary AO input box is proposed empty. The drop-down list is filled in with the most recent IDs you have queried before with success.
All these Where query elements may be associated to the ID of an Aircraft Operator, except when the main query criterion is already an Aircraft Operator .
On initial display, the focus is set on the first mandatory query control with no default value: the Is input control.
A contextual Suspended Flight List may be directly requested from a Flight List display if authorised via the FLS button at the top left of the list of flights. In such a case, the query criteria come pre-filled based on the window where the request was initiated.
The observed period is never forced by the calling function. The default values are always proposed as described here above (Traffic date, WEF, UNT).
When requested from a Flight List, the Suspended Flight List will trigger on immediately the Period Shifting state.

Preparing to query

The traffic Observed period may be adjusted as follows :


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 Where drop-down list provides the user with following selection:
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).
When Traffic Volume is selected, a Flow may be entered or selected from the list of previously queried IDs proposed in the drop-down list.
When Aerodrome or Aerodrome Set is selected, the related category (Cat) must be checked (Global, Departure or Arrival).
When Point is selected, the Maximum (MAX) and Minimum (MNM) Flight Levels (FL) may be overwritten to reduce or enlarge selected altitude range.
A valid integer value (maximum of 3 digits) entered in the Maximum (MAX) box, will be rounded as follow:
A valid integer value (maximum of 3 digits) entered in the Minimum (MNM) box, will be rounded as follow:
All these Where query elements may be associated to the ID of a most penalising FMP, where the selected flights must have the most penalising Regulation from a given FMP.
All these Where query elements may be associated to the ID of an Aircraft Operator, except when the main query criterion is already an Aircraft Operator .
Changing the Where value could change the settings of the other query criteria except the period.
The Send button will send the query to the CFMU system.
If an Aircraft Operator code is part of the selection criteria, the query period will be limited to the value of the system property CHMI / ATFCM application / Flights / Flight list / Maximum elapse for AO list.
Otherwise, the period will be limited to the value of the system property CHMI / ATFCM application / Flights / Flight list / Maximum elapse.
This window may be closed before any query is issued.
The Reset action common functionality is implemented for this function. All query criteria are considered for activating the Reset action.

Displaying the query results

The title contains the time stamp when the information was retrieved from the CFMU system.
The optional >> sign indicates that the Period Shifting mechanism will be applied on refresh.
The optional keyword (Poll) between parenthesis indicates that the Polling function is active for this window.
The header box of the window contains the different query data elements used to retrieve the displayed flight data :


At the top of the Flight List, a counter indicates the number of suspended flights retrieved.
This counter may be affected by filtering (fff / rrr Flights where fff is the filtered number and rrr is the retrieved number).
On query results display, the focus is set on the list of Suspended Flights after selecting the first flight in the list.
For each flight the Flight List display contains following columns:
The flight might be suspended for the following reason :
The initial display sort sequence for the Suspended Flight List is Descending order on the E/CTOT column.
The Flight List allows only single selection.
The Invalidate function works for this window, if the user preference CHMI / ATFCM application / General / Dates and times / Activate invalidate functionality is checked.

User interactions

This window allows to modify a previous query selection and to issue a new request.
On query modification, the Reset action is enabled.
To display / hide the query part, click respectively the Down / Up arrow on the left underneath the split bar.
To update the display, click on the Send button on the button bar or select the Action / Send menu option. This will issue exactly the same query to obtain an up to date list.
The Previous / Next period function may be used to issue the same query but for the previous or the next period in time.
The Polling function may be activated to start automatic refresh processing on this window.
The Period Shifting function may be activated to start automatic period shifting on subsequent refresh of this window.
The Invalidate function may be activated for this window. Just check or uncheck the user preference CHMI / ATFCM application / General / Dates and times / Activate invalidate functionality.
To display a sub-selection of the retrieved data, click on the Filter button on the button bar or select the Action / Filter menu option and adjust the desired filtering criteria.
To modify the Sort sequence of the flights, click on column headers corresponding to your desired sort criteria.
To print the Suspended Flight list, first retrieve, sort and filter the data in the window. When ready, click on the Print button or select the File / Print menu option.
To export the displayed details, click on the Export button or select the Action / Export menu option.
Increasing / reducing the window height or width will impact the size of the main Flight list control.

Contextual actions

When a line is selected in the list, the right mouse button pops up a contextual menu.
This popup menu lists the possible actions for the selected Flight and may contain the following options:
