I see in my airline there are mainly 3 different techniques for descent.
the first 2 are to manipulate the primary FPL either by inserting the expect shortcut on the primary and full arrival on the secondary. This is done also during descent according to what happens.
or to put some tactical constraints in order to be ready for the shortcut.
some others simply go blue open des… In your airlines which is the preferred technique? Talking with friends in the orange one it seems also there they like a lot to use man des as much as possible….
