During training I got my first crack at an LP approach last week in to RNAV08 at KDXR. I have a 430 with WAAS. As expected I didn’t get any vertical guidance. So today I and flying an approach into KSEG on the RNAV 35, it too also has an LP approach. But this time a glide slope popped up?!? I didn’t expect it and was not sure what to think about it. I was under impression that I should not get any vertical guidance on a LP approach. While I appreciated it I wasn’t sure I would be able to trust it. Thoughts?
