This is a very specific question, but on my Blacksquare Bonazna, the VSR (vertical speed required) on the GNS530 is showing as blank, when it should be showing my descent speed required to hit my VNAV waypoint and I’m not sure why.
As you can see in the screenshot, in the lower GNS430 I have a 200’ target altitude set 4nm before ENKR. Everything has been entered successfully as the VSR is being calculated on the VNAV page. However the issue is present in the main page of the upper 530 where you can see the VSR field is blank (circled in red).
Any idea why this isn’t being shown correctly?
