I had a strongly held belief that GTN Visual approaches were 3° or nothing, but yesterday into EDAZ 07 I got 3.5°.
Has anyone else seen such a thing?
This is interesting for a different reason: EDAZ bans VFR straight in approaches.

Why? The Garmin functionality with the visual approaches is independent of VFR regulations. It is just a help for pilots to get a glide path where they think it would help.

As far as I know Garmin calculates with a 3 miles final and the glide path is set according to terrain there. But without any guarantee of terrain clearance it is no IR procedure.
For myself, I do use the feature only to set the final course for a vfr approach instead of using the OBS feature. It’s faster and the needle points to the final course direction immediately.

You are right of course, the database does not take local regulations into account. I just sounded like he possibly flew the straight in visual to 07, which sounds very unlikely.

EDAZ has a 3.5° PAPI. I would guess that’s the reason.
Interesting, EGNS used to have a 3 deg. Garmin visual on 08, latest Airac now only gives lateral due terrain.
ILS is 3.5 deg
There are plenty of places with 3.5° or more PAPIs, but a 3° slope. eg Biggin 03 and many others, but I have never seen a Visual approach with more than 3°.

I don’t believe that a database is used as such. I think it’s calculated on the fly from runway orientation and the terrain/obstacle database.

Quite, the filthy lice infested boids don’t like it. But I am always reassured that the world’s Police is out there looking after me.
Maybe Garmin are looking to tie their visual approaches up with the ils/papi etc slope, now they have been in existence for a while?
Wouldn’t it be loverly?
I have asked Garmin and await their answer.
But this is on 3.51, not 3.62, so it’s not like it’s a recent change.
I asked Garmin about this a few weeks ago following customer questions and received the following:
