Can anyone hazard a guess on this one? The plate is for the GPS 3 into 1B1, Columbia County, NY. The airport has a certified LPV approach to 500' with a mile vis. LNAV only MDA is 760-1, and is the same for Circling. What gets me is the LNAV/VNAV DA of 842-2 1/4 which is obviously higher than the LNAV only/Circling minima. Anyone know why?

^^^^^^ link to the plate...couldn't get a copy as an image. Also check out the circling mins of 1SM for cats A/B...doesnt really seem feasible.
This plate is valid from 15 November 2012 to 13 December 2012...just in case they change it in the next cycle.
