Unique Runway Markings, Wellington Airport

DC-8 jets were introduced to Wellington Airport in 1972, with a 180m runway extension - to 1936m (approx. 6352ft) in total. This was still rather short for a DC-8, and special runway markings were introduced unique to Wellington.
Google Maps/Earth (I get them via gc.kls2.com) will show the actual markings, but in brief they are four sets of HORIZONTAL lines on the runway.
My questions are, what do they mean, and thus what purpose do they actually serve?

Sounds like you got a better reply from the Wings Over Cambridge Forum...  Silly
Sorry I can't help you although it does sound interesting.

I can't remember exactly but I just checked (admittedly out of date) IFG and it made no mention of those markings. Perhaps they represent a point where there is no longer sufficient runway length remaining for large aircraft? ie commence a missed-approach/go around.

I am still looking through them, so haven't found anything firm yet but have a look at the following AIP.

Have a look at Page 9, number 5. Those are the markers at 460m, because that's 1500 feet.Wellington Aerodrome

TDZ
LGT
LEN

high intensity white wingbars 460m from threshold O/R


This is what page 9 number 5 says.

Translated is (I guess some people will know these Abbreviations off the top of their head, but I am still learning them all.):
TDZ=?
LGT=Light or Lighting
LEN-Length

O/R = On Request

TDZ is touchdown zone.

I'd be interested in knowing the meaning behind these markings as well...never seen them before.

They are touch down zone limitation markers, must touch down before that mark, die mainly to the winds experienced at that airport.

If they are Touch Down Limitation, this does not affect GA Aircraft. Where touching down one the 2000 foot markers (500 feet past this zone) to minimise time on the runway, as nearly all GA aircraft vacate to the Western Apron, via Whiskey 1 & 2.

I love that video! One of my all-time favorites. I can't imagine the kind of ride the pax in that QF 767 and the DHC-8 at the very end were enduring.

Not sure, understand they have some local GA procedures. I would see no reason why not to land further down in a light aircraft when it is obvious you dont need anywhere near the full length.
