NAT Region Contingency Procedures
Having seen the following this week amongst the NA Track info, can anyone tell me what NOTAM CZQX A0621/06 is? I can't find reference to it anywhere else, or what it actually contains:
ATTENTION PILOTS. INFLIGHT CONTINGENCY PROCEDURES FOR THE
NORTH ATLANTIC REGION WILL CHANGE AS OF 0602160000. REFER TO
NOTAM CZQX A0621/06.
