Supposedly they compensated for that. They have a "Limitations" section in which they discuss some potential pitfalls, including how most alzheimers deaths start after age 65. I will say, it doesn't inspire confidence when Figure 2 of your paper has an enormous typo on it ("Aircarft [sic] Pilots"). I'm not really convinced personally, especially as stuff like Aircarft[sic] pilots seems to be significantly above the average occupation's risk factor. But they also tend to live significantly longer (78 ish?). It seems to me that navigation is still a reasonable amount of a pilots workload -- just look at the effort to navigate the taxiways at a big airport for example. A bigger factor in my view would be quality of care -- an airline pilot probably makes significantly more than a taxi driver, and is more likely to have good medical care, in which someone is more attentive to their situation.
