Yes Mach E. I do only fly privately these days but I was only giving my experience of Part 61. From my perspective, I can't see any real issues with it, but I gotta ask why the change? What was the problem with the "old" way?
I have always flown my renewals in the aeroplane and a typical flight was and RNAV appr, and ILS and an NDB appr (if I wanted the latter - which I never use anyway).
Under Part 61 I need to fly a 3D appr, a 2D appr and ensure I have covered a CDI indicator and an azimuth indicator in those if I want to use them.
Am I a better pilot because of Part 61 - No!
Am I a safer pilot because of Part 61 - No!
Not that I can see anyway - but hey, I know I only operate near the bottom of the piloting dung heap!

PS:....and if someone knows the implication of Part 61 on PIFR privilages - please enlighten me cause I haven't figured that out yet!
