Oh ok, I am noticing a trend today with people that aren’t fedora enthusiast are wearing their brims horizontal straight like a air plane.I’m not sure what you are meaning. Gannon’s fedora brims are flanged and not flat. Most all fedoras have brims similar to your photo. Some have more flange, but all snap brim fedoras have some level of flange.
Traditionally, some brims have more/deeper flange. The Stetson Stratoliners are an example of this. Others have less flange such as the Stetson Open Road. Many hatters have a variety of flanges to offer customers a choice.
Here is the hat I’m wearing today. Viewed on the profile you can see the amount of flange it has:

The cupped “flange” gives the brim tension and allows it to be worn brim up all around, snapped down in the front (as in my photo) or snapped down front and back in the Outback/adventure style. Some hats are made with flat brims, but the only Gannons I’ve seen that didn’t have a flanged brim have been his westerns, and even most of those have a shallow flange.
One of the great things about commissioning a custom hat is you get to decide all the details.
