CRAM Display

Function presentation

This display gives the Conditional Route Availability Message (CRAM) details for a selected date.
Data retrieved by this query are extracted from the ATM Messages Exchange (AME) database.

Opening the window

From the Application / ATFCM menu, select the option ATM Messages / CRAM.

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

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).

On initial display, the focus is set on the only query control: the Date input control.

Preparing to query

The Date may be adjusted to one of the proposed values. Common ATFCM Tactical / Pre-Tactical dates behaviour is implemented.
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.

Displaying the query results

The title contains the time stamp when the information was retrieved from the CFMU system.
The header box contains the selected query criteria : the observed Date.
On query results display, the focus is set on the CRAM detail list after selecting the first line in the list. After this, the focus moves back to the observed date, then to the Availability / Closure button and finally on the FIR selection combo box.
Just below the header box, a text describes the validity period of the CRAM.
This validity period is defined by a Valid From and a To date and time (format HH:MM DD/MM/YYYY).
The next detail line displays the Status of the CRAM with the date and time when it was changed to that status. (format DD-HH:MM)
Possible status for the CRAM :

Init : when one or more Draft AUPs have been received but no Release yet.
Draft : when released AUPs have been received or after the published lead time before the release of the CRAM.
Released : when the CRAM is released

A combo box contains all the FIRs related to the different route portions listed in the displayed CRAM.
This combo box allows sub-selection on all or one specific FIR.
For each Route, the detailed group of lines contains :

The Air Route identifier.
The Route portion identified by the FROM and TO significant Point ID.
The different FIRs related to this Route portion.
The Minimum and the Maximum flight levels (UNL stands for unlimited FL).
The applicable time period (From-Until HH:MM).
In front of each detailed level/period line, a symbol indicates the status of the item.

Possible symbols in front of the detail lines are:

"*" indicates a draft item. It means that the CADF assistant cannot edit the route portion. The data was transmitted using the "draft" AUP and is not stored in the CRAM tables.
">" flag indicates a released item. The CADF assistant can edit the route portion. The data was transmitted using the 'released' AUP and stored in the CRAM tables.
" " (blank) indicates an edited item. It means that the CADF assistant has edited the route portion. The data is stored in the CRAM tables.

The sorting for the route in the CRAM will be as described below :

the first criterion is by ascending order of the first pure alphabetic part of the identifier (first group of letters from which the prefix (first character equal to 'K' , 'U' or 'S') has been removed e.g. AB123 comes after A123, B123 comes after AB123)
the second criterion is by ascending order of the first pure numeric part of the identifier of the route (first group of ciphers following the above group of letters e.g. A123 comes after A44)
the third criterion is by ascending order of the possible third alphanumeric part of the identifier of the route (first group of letters and ciphers following the above group of ciphers) (e.g.UL613 comes before UL613D)
the last criterion is to present the route with a prefix (by ascending order of prefix equal to 'K' , 'S' or 'U') just before the route without prefix (e.g. UA44 comes before A44)

Two exclusive Radio buttons allow to display :

The Conditional Route (CDR) type 2 Availability.
Or the ATS Route and CDR type 1 Closure.
