Did the PIFR paperwork beat your CIR renewal paperwork to Canberra? ATO never signed off on anything for me.
This is your friendly CASA FIO here.
Seeing as local cops can issue summonsessses through face book, could you please kindly head into your local field office to hand in your PIFR as we have had no response to requests to rectify your paperwork and we KNOW you will be reading this.
For PIFR addition to an existing CIR; just ask the ATO to fill out the extra form at your test. Every ATO I know will do it at no additional cost.
Single vs. Multi; all you need is one approach in a multi with an ATO and the whole shebang gets upgraded. PIFR and CIR.
PIFR vs CIR; CASA made it hard (esp in SE QLD) for schools to conduct the PIFR exams. (Each aid has to be examined separately, Avalon was in a "unique" position, until now.) Doing the the CIR means an IREX (bummer) but you get every FPA associated with each aid, whereas each individual FPA (NDB Holding, NDB IAL requires Vis Circling, Navigation using NDB) must be assessed with PIFR. Much easier to test and you have a higher standard (read as safer) with CIR, IMHO
