This may be how this aircraft was designed but I noticed that the DIST readout on the HSI only works when a VOR or ILS frequency is dialed in and shows the distance to the VOR or ILS when in VLOC or GPS mode. It does not show the distance to the next flight plan waypoint when in GPS mode. Personally, I would prefer it to show the distance to the next waypoint based on GPS mode. Distance to next waypoint when set to GPS and distance to VOR, ILS when in VLOC.
