The Senior Pilot
 

A very interesting article from the NZ CAA, very close to home for me.

PS Nothing to do with one of our esteemed Mods! :)

I'm still doing 300 hours a year instructional in my mid 70s and our examiner who is current on many types including a Cirrus has just turned 80.
As the article says, if you're current and can still see and hear, you're good to go.
As to the heart thing, the ECG is pretty much a waste of time, I'm told; vis the class 1 holding instructor in his 50s who died alongside the pilot he was checking out recently.

TOO

Just as a comment; the instructor in Colorado I used to fly with, was still instructing at around 92 when the FAA decided he should call it a day.

he only outlived his license by about 6 months in 2021.

See comments in this accident report just published.

I've recently decided it was time to call it a day at age 75, no known health issues but I could feel myself taking longer to compute my workload of information being thrown at me, therefore I felt I was getting behind the aircraft.
I will add, this was in the UK, prior to that most of my flying was when I was living in Florida before returning to the UK. If I was still in Florida I think I would still be flying for quite a few more years.
