investigating Systems shutdown during the flight

[petic537]

Hi, this happened to me many times... maybe 5 times:

 

During the flight helicopter systems shutdown randomly for a while. HUD, gyros, ADI, generators, transformers, rectifiers, autopilot, hydraulics, engine gauges were down. After cca 15 seconds systems go up again by itself.

 

I was not pressing any buttons or switches in the cockpit at that time.

 

It happened to me during flight after cold and dark start and also after start in the air.

Any chance you have Game Mode enabled?

[petic537]

No. I do not have Game flight mode or Game avionics mode enabled.

Next time it happens, please save the trk file and post it so someone can have a look.

Had the same, think it was due to being aggressive when applying the collective and the main rotor/engine rpm dropping and causing the generators to drop out (just like they will in the Mi-8 but there we get "generator failure" from the RI-65).

 

I quickly adjusted my flying style, so it hasn't been a problem since.

Ye, looks like when you applied full collective few seconds later everything cuts out.

I have attached TRK file. It is below screenshots.

 

It contains full startup, wobbling in the air and close to end you should see the issue.

my question is: why dont we get RI-65 voice message like in Mi-8?

Whoops, my mistake, sorry I did not notice it beneath the screenshots.

I believe its a known issue? if its the same thing

i see, thank you

Perhaps voice/systems are WIP (it seems strange to need 115v for the EGT gauges, etc.).

Well, TRK file shows it little different then it really was. I was cca 10 meters above ground when it happened. In TRK file it looks like I hit the ground and then it happened.

 

But anyway I had the same issue when I was flying 300 meters above ground level.

I watched your track file about 4 times. I saw when you where hovering about 10 meters, then full collective all system cut, and you crashed on the runway?

Well... yes. That is how it was.

Track does not play back correctly for me. It sounds like applying full collective is causing low RPM and generator failure.

[wowbagger]

It's your throttle setting, I believe. You can you check that you have your throttle fully opened please?

Yes. it was probably because full collective and low RPM. Then generators were not delivering needed power. It happend to me again when rotor was at 72% RPM and engines at cca 90 %.

 

So it was because of my bad flight maneuvers... So it is not a bug. It is a feature.

 

Thank you all for help!!

This had this few times also , this is online play . System will go off line until more throttle is applied . Then sights come back on and regain control .

Not sure if it mean we are pushing the Hind too hard.

Reduce collective to bring them back online.  I'm guessing voltages dipped too much.
