DMG IWXXM-Monitoring

The IWXXM-Monitoring is part of the DMG-Monitoring Procedure. Detailed information on the whole procedure can be found in the EUR Doc 018, App. C.

When does the IWXXM-Monitoring take place?

The Warning Monitoring is part of the DMG-Monitoring which is performed each year from the 1^st until the 14^th February. Just like for the alphanumeric (TAC) OPMET data, the monitoring centres also collect information on the received IWXXM-messages. Based on this data different information can be retrieved.

The detailed specifications on monitoring IWXXM-messages can be found in EUR Doc 018, Appendix D, chapter D.3. The latest version of that document can be found on the ICAO-Paris Homepage (Path: EUR/NAT Documents / EUR Documents / EUR Documents / 018 - OPMET Handbook).

IWXXM-Monitoring Results

The following list shows the number of Location-/FIR-Indicators for which IWXXM-reports were received. It does not consider whether only NIL-reports were received.

Choose option	What to expect
IWXXM-Version	This request will list for each IWXXM-datatype how many distinct combinations of report and IWXXM-versions where monitored. Also NIL-messages are counted. Higher numbers compared to the general figures above are an indication that some reports are excahnged more than once with different IWXXM-versions. Also NIL-messages are counted.
Operational	This request will list all IWXXM-datatypes, how many distinct reports have been received and how many were defined as being an operational message, a test or an exercise. Also NIL-messages are counted. Higher numbers compared to the general figures above can be explained by the additional counting of the test/exercise messages.
Translated	This request provides an overview on how many reports are translated. NIL-messages are not considered which explains a lower number compared to the figures on received IWXXM-reports above.
Translation Failed	This request provides the number of all received reports of the different datatypes and how many of these included the inforamtion that the translation failed. Further investigation are necessary to identify the reason(s) for failing ideally providing feedback to the originator of the message and/or the tranlation centre.
Global Availability	This request provides the global availability per ICAO-region for all AOP-aerodromes. Reports which have been received only as NIL throughout the whole monitoring period are not counted as received
