RNAV appraoches - decent path below the glidepath

[matpietsch]

With the RNAV apporoaches the decent path of the plane is consitently to low. Every time I see four red PAPIs.

Which RNAV approach are you flying?

Check out these. They are all ORBX so I can’t rule out that ORBX placed their PAPIs wrong. However, with other planes I got 2 red /2 white. I will test further on other airports.

  KBZN RNAV Y RWY 12
  KSUN RNAV Y RWY 31

It's hard to say if this is KA-specific. What other aircraft works fine?
Here are two screenshots taken at KVPS - with KA and default Maule. Both experience the same issue - while on path, both papis are red. Getting white/red at ~500ft in both cases.

I have also noticed the VGS will bring you in low and short of the runway on RNAV approaches. I think this has to do with a couple of issues with Navigraph data the least of which is no FAS DB for SBAS enabled approaches. One of the software engineers will have to provide more information on the current status.

For now, I'd recommend sticking with LNAV minimums only.
