I'll take an instrument student into actual on lesson one. We won't spend that time working on approaches, instead I will get a block of airspace from atc for us to maneuver in and we'll work on the same thing I would have had the student do under the hood in vmc.
The end of the lesson of course ends in an approach that I walk them through but the focus of the lesson is building the core instrument flying skills needed in that block of airspace.
And that's what we did. We weren't even expecting the fog but it completely changed my mindset about what and why we were working on the rating and what the end goal and accomplishments were for.
I had way too damn much sim time where everything is safe and the world can be reset.
An approach to minimums on night number one (knowing that we had a reasonable "out" and VMC all around) still gave me a completely new perspective on what the hell I was doing it all for.
And frankly, I feel damned lucky to have stumbled into an instructor who wasn't afraid to fly whatever weather was thrown at us and teach how to assess it and make decisions about it.
Not everyone gets so lucky as to have a fog bank roll in over the airport at night on day one. I wouldn't trade that night for the world. It makes the hood time, for lack of a better way to explain it, seem meaningful later, once you've seen it. It also gives an anchor of importance to it all.
Which frankly, is why I'm now out of currency and don't plan on being back in currency until I have the correct amount of time and focus to both need it and to do it right. I don't belong inside a cloud again until I've had one hell of an IPC and beat some things back into habits again. And it might take years of hard IPCs to make all those habits permanent.
My advice is, if you can't get any real weather time during your training, fly to where you can and do it. And later, go find more and stay sharp. If you're not staying sharp, just stop until you can.
Or just go visit Jesse in December. Ha. He's on my permanent "I'm buying beverages" list. Something he taught me or showed me (like all good instructors) will eventually save my life, of that I have zero doubt. May not be this year, may not be next year, but it will happen. There's other instructors on that permanent beverage list, too. And a couple of them have saved my ass with their voices in my head over the years.
