Here's some more platitudes, brought to you by rum punch next to the pool...
I thought a lot about the system I was a small part of during flight school, I wanted to make sense of it for my own reasons. Here are my thoughts.
NSS is not a number that says how good you CAN be. It's a trajectory. "How fast can you get high". But, there's undoubtedly a correlation to how fast someone learns and how much their capable of.
The "luck" of instructors and the whole conduct of a flight is like sandpaper. One pass and it would be very much luck on whether you got the hard ass, a real gnarly piece of grit who leaves a groove, or the Santa claus who barely takes anything, but let's a knot protrude. Enough passes and repetitions and it evens out.
To labor the analogy, there isn't just a mindless belt sander running things, there are skilled craftsmen watching the process. My NSS was nothing special, but I worked my ass off, made a few good catches and calls, and did my best. What I was good at, bad at, and able to learn better was recognized. I still believe my primary squadron Skipper tipped the scales to push me in the direction that would be good for me and the navy.
The process of flight school is dispassionate and can often feel like "the best you can hope for is apathy". IMO the reward won't be praise very often, but rather self actualization.
And on the flip side, would you rather be the guy who got "lucky" and everyone went easy on? Im no navy seal writing a book, but the hard days you have will make you better sooner and in the long run. I'd take that over being the guy who had it easy and got his world rocked later in the pipeline.
The part about taking notes in the debrief are solid, but i challenge any student to come up with notes for the brief. Tattle on yourself for what you aren't great at (2-3 items) come up with what you think will help and ask your IP what they think.
Don't leave it to them and the grade sheets to make you better.
