I was not intimating that doing an RNAV without approval in anyway contributed to this accident but it certainly opens up a legal can of worms.
A bit like the PX Boeing fleet office giving tasid approval to conduct Autolands in POM below the CAT 1 minima in preference to diverting.
As we all know conducting LVO operations involves far more than just aircraft capability. Not withstanding the POM ILS is only CAT 1.
All in the name of getting the job done.
And yes I agree time will tell.
