no speed indicator

hi. sometimes when I play DCS black shark 2 there is no speed indicator in the top left of the HUD.

how do I fix this (to see the speed in the top left of the HUD) ?

many thanks.

be faster

if you are too slow, you will get the line in the middle of the HUD

and there's always the speed indicator on your SHKVAL

HUD is indicated airspeed and needs ram air to work. Shkval is calculated airspeed.

What does ram air mean?

RAM = Airpressure buildup in the pitot tube by forward airspeed (ramificated air)

If the forward airspeed is to low the hud switches to low speed mode ie Hover..

Or, your INS hasn't aligned yet because you've started up too fast or forgot to turn it on.

The INS needs some time to get ticking, once it does though, your speed will show in the HUD and you know the INS is aligned and ready.

Thank you Looney.

I have wondered about this as well for a long time (too minor issue and too lazy for me to ask myself, thank you m1tp2king for doing it).

The ram air explanation doesn't fit, since I can fly above 200km/h GS without a reading on the HUD a while after startup, and when it finally appear (it always does eventually) I can go down to almost hover speed and still have it.

I can't remember if I have checked the IAS any time when this happens, but I assume it's driven by ram air + ambient pressure exclusively, without the INS being involved.

Should show up after 3 Minutes after Startup in Nav Mode

Or sometimes, uncage the skhval, then cage it again to reset the HUD flight mode, and it makes the airspeed back, sometimes.

Or just watch the IAS dial???

IAS is just that, it doesn't show you ground speed.

But so doesn't the HUD either for what I understand. Or am I wrong?

My experience is that the HUD correlates more with the IAS than the GS on the ABRIS.

Or just watch the IAS dial???

But steam gauges are ugly!

IAS is also useless under 50 km/h. You need to look at either the speed on the HUD, which is from your INU, or the ground speed on the Abris, which is from the Glonass satellites.

Use the reset button on left panel, where you have that set of 4 buttons for the skhval
