Title: VNAV treat At or Above constraint as At
Post by Angel of Attack on May 15th, 2021 at 8:34am
I'm on 0302 and P3Dv4.5HF3

Set an approach to ROAH RNAV18L, there is an altitude constraint on KUKUL as 2000A, and about 10nm down the range, there is another constraint at RYCOM as 1200

Normally you only need about 2~3nm to descend from 2000-1200, so the VNAV should arcoss KUKUL well above 2000feet (about 4000' for that distance), but in this approach, it's right on 2000, as if it's an "At 2000" constraint.

Saved are just 2 mile before KUKUL.

BTW overall the VNAV PATH descend are working great, much better than 757 for now!
