This is actually a question for Blastoid (following on from the Virgin TCAS RA thread). As I said on page six of that thread (re: MIL aircraft requesting block levels in Class E):
That's an interesting point, capitan. I was under the same impression, because I distinctly recall in the training package that block levels were banned to ALL aircraft, however, I noted in MATS yesterday that block levels are now banned to CIVIL aircraft only.
Then I noticed your post down the track that said no block levels (including for military aircraft). The new MATS says:
Block level clearances
6.1.2.19 Block level clearances shall not be issued to:
a. civil aircraft in Class E airspace; or
b. aircraft to which the Mach Number techniques is applied.
so I'm just wondering whether you guys have got some local procedure/arrangement? What about around the rest of Oz?
