Absent a failure indication (or inappropriate FMGC programming) the aircraft will level off at FCU selected altitude. The current indications: altitude window flashing yellow when approaching within 750 feet of the FCU‑selected altitude and FMA change already indicate the aircraft will level off at the FCU set altitude.
ATC assigns a vector 90 degrees off the STAR. I input that heading and pull. The aircraft lateral mode immediately goes to HDG even though the aircraft is yet to be on that heading. In this case we make the assumption the aircraft will turn to the selected heading and roll out.
Why is there not a “HDG*” indication until the aircraft actually rolls out and “captures” that heading?
