Why don't you tell him some guy on the internet posted verifiable
documentation that proved him wrong? Wouldn't that be more beneficial?
Then he might stop providing CFIs with incorrect information and they
wouldn't be passing it on to their students or posting it on the internet.


Enter a taxiway or other "protected area" at a towered airport without
clearance, it's an incursion.


It's a runway incursion only if that other "protected area" is designated
for the landing and take-off of aircraft, aka a runway. Do you understand
that?



I've seen it happen, confirmed that it
was reported, and discussed it with the FAA after their Runway
Incursion seminar.


It's likely you misunderstood what you saw and heard.



I don't care what you read on the internet.


No? You wrote, "So, if you have something in an official context that you'd
like to share, do so." I did exactly that, and now you say you don't care.
I'm hurt!



Readers are free to form their own opinions and choose their own
safety practices.


Yes, your memories versus verifiable, definitive FAA documents. I know
which way that will go.



I'm just telling people what happened.


As best you can.
