Great Update. Thanks PMDG..

Hi,

Nice, looking forward to checking my hardware for their Improved flight control handling/feel for all 737 types. One of my biggest gripes.

after this update, both the PMDG 737 and PMDG 777 are able to correctly and accurately fly every defined leg-type used in modern navigation.

Not quite.  I haven't tested the 737 yet, but this new navdata format and logic in the 777 is unable to parse an RF segment to a runway waypoint - you still need a pseudo waypoints 10ft prior to the rwy waypoint.  An extremely minor detail, but it is true.

LNAV auto-arming to provide lateral guidance for a go-around from a ground based approach (ILS/LOC)

The wording of this one is weird: why only on ground-based approaches?  When this option is enabled in the aircraft, it works on every approach type in the database.  It's normal to be flying an RNAV approach and see both a green active LNAV annunciation, and a white armed one.  Odd that they would limit this feature to a loc-based approach.

There is post by “LRBS” in another thread where he is flying the RNP-Y RNAV 29 approach at KEWR and he had both green active LNAV and white armed LNAV, so it appears that it is indeed implemented properly. He also showed the aircraft as being 0.42 nm off course to the outside of the turn to final. I will have to try that approach this weekend when I get home from a road trip and have a chance to download the 737 update. I have flown several RNP procedures in the 777 and have never seen it wander off like depicted in his screenshot.

Just posted my results in the forum and it primarily stayed within .01 nm through the procedure. There was one quick instance where it deviated to .04 for a second or two. Looking forward to seeing your results.

Notably while the ND was still displaying "ANP 0.06". Gee, I wonder what the "A" in "ANP" stands for...? 😉

Actual Navigation Performance for ANP and Required Navigation Performance for RNP.

Thanks, I knew that, hence the "Gee" and the winking smiley. I was taking a dig at the fact that the plane isn't "actually" achieving the "actual navigation performance".
