TACAN distances difference map/ HSI

[VTJS17_Fire]

Hi,

 

if I start from Senaki (Blacksea map, DCS World open beta 1.5) and set the TACAN to 44X I got the signal from Kutaisi.

 

The HSI shows about 10 NM from Senaki (ground, parking 2) to Kutaisi TACAN. After that distance I'm direct above Kutaisi.

 

But: In the F10 map and mission editor, it reads 19,98 NM with the measurement tool. So, where is the bug? In the HSI or in the measurement tool?

 

And yes, I set imperial in my options.

 

 

Kind regards,

Fire

I can confirm this.

 

It seems that HSI distance is always half of the actual distance. In my case: Kobuleti - Kutaisi on map ~ 30 nm, on HSI 15 odd nm

I also noticed that something is weird about it. I think the aircraft actually displays kilometers instead of nautical miles (wrong by a factor of 1.8 ) or something like that.
