When I read your original post and some of your responses Doug you sounded a lot like some of the people in my brain injury support group.
BRO! You get it! Glad to hear you're flying; that gives me much hope. Thank you for sharing.
I was very lucky. Mine was pretty minor in the greater scheme of things. I fell, banged my head on a rock, and was out for about 5 minutes. It took me about 6 months to get mostly back to normal; no loss of speech or motor skills. I wrote code at the time so the cognitive loss was...worrisome; nothing like looking at something you wrote last week and realizing it is total crap but when you wrote it you were 'in the zone' and doing great work. I'm also acutely aware that I'm no longer able to process as much information as quickly as I used to. When I'm driving and get into complex traffic, the radio goes off and nobody talks to me; I just can't handle anything more than driving. Flying is driving * 10...I equate it to trying to juggle 3 running chainsaws while balancing on a big rubber ball that's on a trampoline while trying to give the Gettysburg address while listening to important directions while people are throwing heavy rocks at you...
I had a neuro at about 6 months post-injury. With no pre-concussion baseline, the results were mostly above normal with a dip in my auditory recall that was outside of expected ranges (but still inside 'normal' limits). I'm having another in Dec with a guy who trained at the Shepherd Center just to see where I am today. Most days in regular world, it's not a big deal. The challenge is recognizing the days I'm not safe to fly since the world inside my head doesn't always tell me 'you're a mess, stay home today'. My wife was a special ed teacher so she's on board to assist.
So, when you take the issue with auditory processing (translates to missing radio traffic), couple that to not the greatest short term memory, age, bad eyes, and not the world's best fine motor skills you're left with a very nervous student. The good news is that I'm fully aware of my shortcomings and I am working to develop reliable processes to deal with each specific issue. I write things down and am learning to plan out the next 5 minutes so I'm not trying to figure out what to do at the instant I need to do it.
Regarding eyes, yes, wear progressive lenses. Peripheral vision is fuzzy. When I'm busy trying to land, peripheral is totally gone due to information overload. If I want to see outside the window, I'll have to turn my head and look. I think what I'll do is let me CFI know that I want to check out my side window and ask him to compensate for any pitch errors for a couple of landings just to see if I can correlate what's up front with what's on the side.
Regarding inhale/exhale...what are these 'hale' things of which you speak? Crap, you want me to do all the stuff associated with landing AND breath??? Right about the time the plane is dropping to hit the runway, I tense up and just hold my breath. I have managed to not have a death grip on the stick but, yeah, I need to relax and breath. I'll add that to my list of things to do. Good catch!
Thank you all.
