The first officer goes from flaps 20 to 30 skipping over 25. Is this normal? It makes things a little harder with such a big config change on approach.

We modeled a real-world 747 operator's SOPs.

 

That's the way they do it.

 

They skip Flaps 25.

 

Best,

Thanks for claifying. This is my favorite of all your products that I own!
