UA169 (VCE-EWR), aircraft or parts of it hit truck on I-95

I’ve seen that note on an approach as well. It wasn’t at BFI, but I’ve seen it.

This note is on quite a few approaches.

It's as simple as this...the electronic glideslope/glidepath will guide the aircraft to 1000 feet down the runway at a particular angle. The VGSI will indicate something different.

The VGSI may or may not have the same angle as the electronic guidance. They might both be 3.00 degrees, but if the VGSI is physically closer to the approach end (say, 600 feet instead of 1000 feet), the VGSI will guide the aircraft on a parallel and lower approach path.

In a few airports the VGSI is set up for a 3+ degree angle while electronic guidance gives a 3.00 degree angle.

Whenever I see this note, I specifically brief the point at which (or if) I will stop following electronic guidance and begin following the visual guidance because we know the two won't match up and the closer to the runway we get, the more pronounced the difference will become.

The AS guppy mind cannot comprehend

You … you people with your RAAS callouts as a text message on the ND. I can't hate that if only because its basically yet another angle to poke at Boeing for not putting an EICAS on the 737.

My favorite thing about RAAS is that we get some of the callouts (APPROACHING RUNWAY 34 RIGHT), some of them can be heard very quietly (on runway 16 left) and the rest you never hear (maybe they are super quiet and if the thing wasn’t so dang noisy in flight you’d actually hear the radalt countdown? Idk I’ve never noticed it on the JS either…)
