+asterix 150 "MADAP Plan Server - Flight Data Message"
+edition 3.0
+date 2004-08-20
+preamble
+    The main purpose of I150 messages is to distribute Flight Plan data to clients. However, other data
+    items can be sent using I150 as well. I150 messages can be divided into the following sub-categories:
+
+    - Flight Plan (Short & Complete)
+    - Start/End of cycle
+    - Correlation/De-correlation
+    - Conflict Alert
+

+            Note:
+                The Destination ID is irrelevant in CAT150 messages since the flight plan messages are sent to all 10 centres.
+                Hence, the centre identifier is set to broadcast.
