The IREX is the problem
The theory training isn't the issue here- it's what CASA examines in the IREX that is the issue, and this is what drives the theory providers. I have been flying RNAVS for a few years on a private IR...and of course one can and would add them to a full IR, but.... the IREX ignores them.
Knowing how to interpret simple fixed card ADFs, if you have one and if there is still a useful NDB near you, is obviously a good thing and I am not complaining about having had to revisit the issue, but RNAVs are ubiquitous and are (IMHO) much safer, yet they are not presently required knowledge for the IREX. This is what I find so puzzling- just wondered if anyone here knows what the examination branch has in mind, as this surely has to change - soon!
Safe flying!
