Hi FlightDetent,
Is there a way to pull out the overflow lines without clearing the system?
If you think of reading ECAM like trying to read a newspaper through a letter box, then you'll have a better idea how to manage it.
If the number of blue action lines in a procedure (or amber lines on Status page) exceeds the space allowed, then it will show a green overflow arrow. When you've read the bottom line of the page ask "Clear Overflow?" or "Next Page?" and one press of the clear button will take you to page 2 of the same procedure (Status).
