With KdR KG on that one too. I NEVER use it. The number of times I have used anything like LNAV on arrival are few. Either 'on field' NDB and DME or Fix page on the field for 'spatial awareness', plus map showing where the elusive airfield is. On the 737 the runway centreline is displayed anyway.
Whenever I see F/Os (and Captains!) doing it they seem to be prone to losing the basics of 'wtf am I'. If I have
anything there I have the 'worst case' descent profile displayed in case I get an early turn in (yes please
)
