It does not affect the profile, but should you raise the DA to the original geometric value, on a flatter profile the point where slope-x-DA would be further from the runway. That, in turn, should (?) force you to recalculate the minimum RVR / OPS 1.430. Shyte what a can of worms.

While that's exactly what the quoted regulation says, you're seeing only the obstacle side of it, underfire.

I trust you the slope covers me over OCA/H until the LO temp limit and that you guys did your math well. The OPS side has, in addition, some minima as well. Such as the DA is never less than 250 ft on RNP-baroVNAV. That's where the old method was more readily understandable.

Anyways Dutchman95 thanks for coming here, I learned something through your question.
