Ok, so garmin aren’t quite correct on that claim, published data for Egns 08 has been 3.5 deg for a long time, but they used default 3 deg, but now lat only.
Perhaps it’ll be 3.5 soon, or it being offset might be the reason for lat only. Not that it matters much where a procedure already exists, but handy where none exists…IMHO
What do we think they mean by “published data”?
What do we think they mean by “published data”?
Most likely, the various published terrain and obstacle sources that provide the input to Garmin’s licensed obstacle and terrain databases.
I’m pretty sure it’s not that, otherwise places like Rochester and Sherburn would get a steeper slope, rather than the none they have at present.
