| Beidou M3 & M4 Launch NOTAMS
Notices to Airman, NOTAMS, are routinely issued in advance of space launches or planned re-entries so that aircraft can avoid the impact zones. When over the ocean, equivalent warnings to shipping also appear.
They are often a useful source of information to confirm and enhance what is already known about an upcoming launch. NOTAMs issued in advance of launch of the launch of the Beidou MEO pair 2012 April are an example.
Three individual NOTAMS were issued (see below the map). They seem to be for the impact zones four liquid-propellant boost motors, the core of the first stage and the second stage. Missing is something for the nose cone but it may be that China considers it not to be a significant event and it may be expected to happen over the sea.
NOTAMS for Chinese launches tend to have start times a few minutes before the actual lift off so this set hints launch between 20:35 and 20:40 UTC.
