Suspected bug: MiG-29G HUD in km, HSI in miles

[N22YF]

The MiG-29G HUD displays distance to the next waypoint in kilometers, although the speed and altitude on the HUD are in knots and feet, respectively. However, the HSI waypoint distance indicator, which is labeled "KM", displays the distance in nautical miles. This is pretty confusing, and I suspect incorrect - the book Luftwaffe Fulcrums: The MiG 29 - From the East German People's Army to the Luftwaffe says that the indication of all instruments was changed to feet, miles, and knots as part of the upgrade from MiG-29A/UB to MiG-29G/GT when the MiG-29s transitioned from East German to Luftwaffe service. If that's true, many other cockpit indications in our MiG-29G should also be changed, but the waypoint distance is the most confusing since the HUD and HSI disagree and the HSI is mislabeled.

 

The radar range, target range, and target elevation are also given in kilometers, which is confusing because the units for these aren't indicated, so it's not apparent what they are. My understanding from that book is that these should be in Western units instead (which would be more intuitive since it would be congruous with the other HUD indications); if so, that should be changed, and ideally mentioned in the FC3 MiG-29 manual to avoid the ambiguity.

 

Here's a screenshot to illustrate - the HUD reads 18.5 (km) and the HSI reads 10 (nm):
