Have ASA spoken to CASA about getting rid of VORs and NDBs?
To quote CAAP 179a
'4. If a TSO-C129 or C129a receiver is used at any time, or a C145a or C146 receiver is used during a period when FDE is not predicted to be available, an alternate visual approach or instrument approach based on NDB or VOR must be planned.'
Looks like the end of 129's for IFR use and very bad luck if you arrive with a 146 needing an approach when there is a RAiM outage.
There seems to be a lot more 146 fault detection outages than for 129's. Then a 146 becomes a 129 anyway.
Also,
'Automation Induced Complacency
The highly automated nature of navigational calculations using GNSS provides significant benefits including increased reliability, accuracy, proficiency and system monitoring ability. However, it can be difficult to stay alert and detect gross errors when monitoring automatic equipment. The operators’ continuing experience of highly accurate positioning information from GNSS can lead to the assumption of infallibility promoting a complacent attitude resulting in decreased crosschecking of the system.'
Well, that's alright now then... Let's just get rid of VORs and NDBs because we dont now need anything to crosscheck against anyway....
