Runway incursions

I believe you have misinterpreted that article. In my opinion, what
it is referring to as incidents that are now being tracked as Category
C and D runway incursions were still occurring on runways. It's just
that they were considered low-risk, so they were previously
"categorized" as surface incidences instead of runway incursions. I
don't believe it is stating that incidents occurring on other parts
of the airport are now going to be categorized as runway incursions.


Bingo. The definition of runway incursion was changed about a year ago.
Under the former definition an unauthorized operation on a runway at a
towered airport where there was no risk of collision or loss of separation,
while still a surface incident, was not a runway incursion. Now it is. At
no time has an unauthorized operation on a taxiway been considered a runway
incursion.
