Overnight/yesterday there were a raft of Head Office NOTAMs advising of various closures and operating restrictions due to Airservices. Restrictions ranged from "relevant approval from operating authority" and "access authority" required to "limited SIS provided" and "expect delay for clearance" alongside "pilots considering operating IFR in class G airspace shall contact Airservices by telephone" and "prior to operating in the TRA, pilots must obtain a briefing on contingency procedures from Airservices".
Sometimes TIBA procedures are in force, sometimes not. Times vary from 40 minute periods to 6 hours stretches. Amongst others, Darwin, Gold Coast, Cairns, Ballina and Brisbane Centre were affected. A "helpful" contingency map address is put in the NOTAMs to alleviate any fears /s
www.airservicesaustralia.com/notammaps/index.asp One NOTAM listed no fewer than 75 air routes affected by the outage.
I'm not sure what pilots are supposed to make of this fruit salad of airspace and procedures. I wonder if airlines can expect a reduction in enroute and navigation charges seeing as limited to no services are being provided.
