Where can i get information what will be the best ALT to fly when im planning my flightplan like for example KATL TO KORL
Depends on definition of “best” alternate. If you’re just looking for one that has the required weather, check the following link:
The Java tool gives a graphic of the selected regions METARs, and you can narrow it down from there.
Altitude or alternate airport?
I thought he meant altitude at first Mark, but that’s so dependent on the type of aircraft that I then thought he meant alternate, but that’s rather aircraft specific as well.
Figured I’d wait and see if any more info was forthcoming.
