Lefty,
Answer 2 seems correct.
Checking the usable runway length on the Jepp T/O Minimums, the diff at DRW is 429m Vs an average of 300-330 m for most others. which implies the gp intercept of the rw is further in.
On another thread Renurpp mentioned the 29 T-VASIS doesn't align with the 1000' touch down markers so this seems to validate this assumption (Yes I know...never assume anything
)
Maybe something to do with the Arrester cable position ???
