BS in BS out
I am astounded that this report has used derived data from questionable sources to come to the conclusions that it has in particular data from an aging private pilot group in the USA. That group is not monitored medically or practically in the manner professional pilots are.
There are several nations that have increased age limits and some with no age limit (Australia and New Zealand etc) yet data on the actual events of incapacitation and other incidents that may be age related has not been used.
The other curious factor is that there are established criteria for acceptable rates of systems failures used in the design of just about everything on an aircraft. It appears to me that the standards being applied here are way above those required for other systems on the aircraft particularly on multi crewed aircraft.
Age limits are just another form of discrimination ..... Medical Standards and Cognitive testing are not discriminatory and that's where we should be. If safety is really the issue those standards should be improved and apply to all pilots no matter their age.
