6 Transitional — GPS Oceanic
If, immediately before the commencement of this Order, the operator of an Australian aircraft held a GPS Oceanic approval, he or she must cease using the approval 2 years after the commencement of this Order, unless the approval sooner ceases to be in force because it lapses, is surrendered, is revoked or is replaced by an RNP 4 navigation authorisation.
Note An RNP 4 navigation authorisation, issued as appropriate on application under Subpart 91U of CASR 1998, may replace GPS Oceanic approval when the latter ceases to be in force.
