[CORRECT AS IS] Slant range indications wrong

[Swift.]

The slant range given in the HUD and FLIR display shows distance over the ground instead of slant range.

 

In the track you can see the altitude at 25,000ft(4.1NM)+ and the slant range reduce to 0.0NM, indicating that it isn't actually measuring slant range.

I've played another F/A-18 sim that I can't mention specifically due to the rules here, but it's generally pretty accurate. It says only TACAN shows slant range - otherwise it's the horizontal distance, including to an A/G Target designation. Of course, if you have real-life info that says otherwise then I'm sure you're right.

Wags describes it as a Laser range, in this video. The laser will range slant range, not range over ground.

 

I would also caution against using other sims as evidence, as other sims have a tendency to be less accurate than DCS in a lot of things.

I'd imagine he's referring to the fact the range has been determined by laser (which is something that's not properly implemented yet). Correct, the laser will get slant range and use that to find where the Target is in 3D space (paired with left/right and up/down azimuth and altitude). That doesn't mean the avionics can't convert it to range over the ground for display to the pilot. But I guess we'll see what ED says based on their documentation.

 

In some cases you're right, but particularly in terms of avionics systems in the Hornet I wouldn't say DCS is the best a lot of times. (Again, for the Hornet.)
