...still not clear!

I tend to agree with DFC's explanation. Now then. Where can we find appropriate regulation that clearly defines this. I have been through AC 120-29A several times, and yes it mentions that the baro VNAV can be used up to a temp. of -25C, but it does not clarify (I think), if the DA should be corrected for cold temperature.

The DA for PANC RNAV GPS 07R shows [ "DA(H) 660' (530') ]. To my understanding, terrain at the DA is still a concern, and even though you descend on a corrected VNAV path, the DA still should clear the terrain appropriately.
