A good captain will encourage his first officer to question what the box is telling him by cross referencing the navaids.Unfortunately modern societies use of technology has led to a generation who trusts technology implicitly. I grew up in an analogue age and still use multiple sources to validate what the box is telling me.
Recently one of my FOs was caught out because of the way he had sequenced the box and hadn’t validated it against the ILS-DME or the VOR on the far end of the runway.The difference in track miles was twelve and it left us a bit high. An orbit sorted it out.
