737 Vertical Profile with Extended Centreline
What does the vertical profile on the EHSI actually show when you have an extended centreline displayed?
eg) You're downwind (or base) 5 miles abeam the centrefix. Does the profile assume you are at the centefix heading the right way? Or, does it allow for the track miles required to turn and cover the 5 miles + between you and the centrefix?
