I hear you on that. I’ve gone through two retinal detachments and after having them repaired, developed cataracts in both eyes. LASIK several years before this happened didn’t help. I had a whale of a time getting my first-class medical renewed and had to get a SODA to do so.
I would assume that each aircraft would have a config file somewhere similar to the one you mentioned in your post. Have you found this not to be the case?
