To take up on the Jepp v AIP issue:
NFR, it may be correct to state that the AIP is the 'senior' document, but the reality is that a significant proportion of the IFR pilots are Jepp holders and are familiar with Jepp referencing and formatting.
They also do not carry a Manual of Air Traffic Services (the 'most senior' document?). They have a legal "AIP" in their Jepps.
AirNorth and NJS/Airlink/Coastwatch ops require their crews to use Jepps. I think this is the same at Hardy, not sure of the GA IFR ops, most of Pearl and the Westwind boys & girls have Jepps in their navbags, I suspect all international visitors and QF are running with Jepps too.
It would have been much more PRACTICAL and USER FRIENDLY communication if the notam had said "Enroute Supplementary Australia ch 1-7 to 9 1-11 to 13 RADIO FAILURE PROCEDURES" and perhaps included a Jeppesen equivalent reference.
Surely even in a cash-strapped RAAF ATC wing, a copy of Jepps in the cheapest binders could be arranged?
