I disagree. I don't think it was ever really true, but it's definitely not true today.
If you change the statement to "The most proficient most recreational flyers will be
at the task of hand-flying without visual reference is on check ride day," I can agree. But while an essential skill, that compromises maybe 10% of what flying IFR is all about. (I used to say 20%). If they're so proficient, why all the discussions about taking baby steps after the checkride?
IMO, the "typical" pilot who passes the instrument checkride, even in the past, has a very limited skill set, almost zero real world experience (even if they trained in actual). They never did a visual approach, didn't have to figure out how to fly an ODP, barely knows what a SID or a STAR is, probably never got an enroute amendment on the CFII-packaged instrument cross country. Depending on where they trained, they may have accomplished 90% of their approaches without talking with ATC and are still mic-shy. The list can go on forever.
The flight portion of the checkride is three approaches they've done 50 times during training, a bit of "loss of primary flight instruments," and unusual attitude recoveries. If they're "lucky," the applicant will get a non-published hold. It may be a challenge, but it is a test of basic skills, not overall IFR competence. The toughest part may well be DPE-induced stage fright.
At least back then, the avionics themselves were simple which meant it was at least feasible for a typical applicant to push into the clouds soon after the checkride.
In 2025, let's add modern avionics. You don't have to go further than the questions already-certificated instrument pilots ask about how to use them, never mind my "GPS Tasks Pilots Don't Know How to Do." I'm sure I've told this one before: There are a few large flight schools which which travel to my home base for their students' checkrides. The trip is usually 2 applicants and an instructor in case something comes up. Iusually spend some time speaking with the instructors. One day, while one of their students was doing their instrument ride, I sat down with the instructor.
Me: Assuming your students pass the checkride today, are they prepared to file and fly IFR tomorrow?
They: Absolutely not.
Or are you saying that they really are the most competent they will ever be, so stay the heck out of the clouds and the system?
