HUD failure in mid-flight, what to do?

[ravenone]

Just eject from your aircraft or crash it and get a new one. You'll note that HUD works on new aircraft..

 

 

LOL... yeah.. and be forced to depend on ground speed and evasion techniques to keep the crew chief from initiating blunt force trauma procedures... directed at me of course...!?!

[David A Sell]

Hud failure is why steam gauges were invented..... I think ;-)

New feature in DCS A-10C: Yell at flight mechanics!

Lucky me, I managed to get one of these inexplicable HUD failures right after starting up the jet. Want to take a crack at explaining this one? Here's the track.

Ram question

 

To the guys having the HUD fail on them.

How much video ram does your card have?

I'm wondering if somehow you are running out of resources.

I have not suffered it yet and am running a geforce GTX460 with 1gig on board.

I just had my HUD quit on me for the second time in about 6 flight hours. The first time I had been hit once with a .50 from a tank, so I thought nothing of it. The second time I was not even hit once and the HUD died seemingly randomly.

 

What I also experience is the KIAS in the HUD and airspeed indicator remaining constant from a certain point on, last time it stayed at 231 KIAS for the rest of the flight until the landing. When I stopped on the runway it read the usual 50.

 

My card is a 9800 GTX with 512 memory.

This looks like CADC partial failure. You can check CADC status on CDU. Also CADC and MASTER CAUTION lights will be activated in case of total CADC failure.

Can confirm the HUD failure, but no idea why it occurred. It is interesting to note that on the STAT page it's indicating a problem with the EGI in your track. Actually I don't know if it's indicating a problem or not - but the EGI line is blank/missing from the display. See screenshot below. Might be unrelated, of course.

GTX 295 here, so I don't think video memory is the problem. The game continues to run normally with no other glitches or anything - it's just as if you've switched the IFFCC off. The game refuses to make the HUD the SOI as well, so it definitely seems to know about it.

Next time it happens I will check CADC status on CDU and see if that is the problem. Thanks!

Is there any backup sight/reticle in case of HUD failure?

I had this with your track, too.

I have an ATI 5750 with 1GB memory. So don't think its video memory.

 

I think we need the virtual groundcrew and engineers quick ! :D

Wouldn't it be awesome if ground maintenance service can also repair your damaged plane instead of just refueling/rearming? :) Would bring a whole new meaning to flying a damaged plane back to base.

[cctoide]

I think they already do that... not sure if it's in the A-10C beta yet, but in Black Shark if you landed on a FARP pad your helicopter would be repaired after a while (engines had to be off, IIRC).

at least you have your gun left and you can aim it by the traice... ough.

 

 

 

:D

I just had a random HUD failure on a routine Nav flight. I tried recycling the IFFCC which had no effect. I have two EVGA GTX 480 video cards with 1536MB each. Hope this helps.

It was mentioned earlier there is random failure built in the sim. If it's true how come everybody complaining about only the HUD but never about any other system? Or maybe this is the only failure which works in the current build?

[Zomba]

I had a "CADC NOT READY" warning come up on both MFD's. I was at 21,000ft doing a wide orbit around some old T-55's and practicing marking, SPI slaving and Maverick arming. I had forgotten to turn on Pitot Heat, which is the only cause I could think of. I had lost all barometric and airspeed sensing. I recycled all electronics, but no go. Silly me.

 

A real pain in the arse, but excellent fidelity.

Just hit the declutter button! I am sure there is a proper way to do it, but in a gunfight I just wanted it off the screen

 

I just finished taking on 4 BMP's in a gunfight in the middle of the street. Shot up all my electronics. Lost both MFCD's and most of my gauges. I had know way of telling altitude or speed. I still had my compass and I headed for the Runway. I still had hydraulics, so I kicked my flaps down and when they dropped I knew I was under 200 knots. Dropped the gear and plopped it down on the Runway! It was freegin' beautiful!

 

....just when I thought this Sim couldn't surprise me again, it slaps me in the Face! Better then SEX!!!

[Galwran]

You do the check to find out whatever you're testing is not broken, and if fails the check you'd ask the ground crew to replace it before taking off. But since simulating all that is probably not practical, just having the check procedure "repair" it would have a similar effect. Mostly it would encourage you to actually do all the proper ground checks as you'd have a real reason to do it, or you could choose not to do it and risk a small chance for failure.

 

 

 

Seconded.

 

I believe that his could even be implemented in a pretty simple way. Just add an algorithm to the error probality calculations so that the chance of failure in certain instruments is greater IF the buttons of the instrument haven't been used during the first 10 minutes of the mission. So basically you just log every button press (just like now?) and use their timestamps to do the calculations.

 

Example: lets say that that during flight a certain component has X% failure propability per minute. If the said component was tested in the beginning of the mission, the error probality might be something like 0,1X% per minute. You could choose the X factor in the mission editor.

In case of CADC failure you can still use old gauges - they will work without CADC. And you can switch barometric altimetr to pneu mode any time - it will be working without CADC.

You can use AOA indexer left of the HUD to control your speed while landing without airspeed information.

Hey Gonzo, awesome rig !! going for the warthog ?
