Altitude Mission - how do you keep the KA-50 flying?

[Rant6]

I have finally had enough practice seat time to try my first mission, and so I have flown the "Altitude" mission several times. At the same point each time I get an EKRAN warning about ice buildup, and so I turn on the rotor anti-ice switch, but shortly thereafter the engines die and I crash. During one attempt I turned on the rotor anti-ice system BEFORE I got the warning, but I got the warning anyway. (Apparently systems failures are scripted into the mission?) It seems like, as soon as I select Waypoint 3, the engines die and the KA-50 falls to the ground. I have not been able to prevent the engines from dieing, nor have I been able to restart them while I am falling. I wonder if I should reduce altitude, but then I will be outside of the mission parameters, and I may not have enough altitue to get to the LZ. Can someone give me some tips to get through this? Thanks.

Welcome to the forum,

 

you might want to use the search feature as there are lots of posts concerning this mission. System failures can be scripted, but are not in this case.

 

Hint: The engines have their own icing protection for a reason. ;) Rotor anti ice only heats the rotor.

I think i know which mission that is, as i posted a question about it some time ago. Do you have to try and climb over some mountains? The answer i got was that in order to achieve a good climb rate and not push the engines to their full, was to ensure i had a forward velocity of about 130KM/h, which is optimal.

 

Here is my thread, see what you think

Thanks guys for the responses. I did try the search, but apparently I need to work with it a bit because the results did not seem to be relevant (searched for "altitude mission"). It looks like, in the mission, that the engine anti-ice is already on (switches are up), but I may be mistaken. During one attempt I did flip the engine anti-ice/dust protect switch. The switch went to dust, and the engines immediately died. I was thinking that this is a 2-position switch, but perhaps I'm wrong. I'll check the manual.

[Frakin Toasters]

The switch you are referring to is a three-position switch, one for dust, one for ice, and the centre for off.

 

I guess you'd be stuck if you were in a blizzard and also in the sahara

Nope, anti ice activates anti dust as well IIRC.

[Frakin Toasters]

Then why does the switch have three positions? I was just flying dude, it has three.

Yes it has three positions. Anti ice/dust, off and anti dust So you can activate anti dust on it's own. ;)

That's an interesting assertion, Sobek. Any links or information why you believe that's the case?

 

Intuitively, ice and dust are two very different things and one would expect the protection systems to be different - filters/separators for dust and heat for ice. Plus, the switch labeling suggests two different functions in each mode and the anti-dust light does not come on when the anti-ice system is activated. If both systems come on in one "mode" or the other, either the designers left out any indication, or the sim has a bug!

 

If you have a link or something that shows that both functions are active when you select anti-ice, could you (or anyone else) post it here? I'd be very interested to read about how/why that's done!

[sobek]

I'm referring to alphaonesix who mentioned this, if i'm not mistaken. Can't find the post right now. Anyway, both systems use compressor bleed air, it seems. For the exact mechanism of anti ice and to why both are turned on with anti ice, you would have to ask a technician like ao6 or airtito.

 

Edit: Look at this post, the thread is interesting to learn about the dust protection system.

Here's a thread I found when searching for "Altitude mission" in thread titles, rather than entire posts:

In any case, Altitude does not include any scripted failures. Your engines are dieing either because you are pushing them too hard in the climb (yellow lights are on for too long - too much RPM for too long) and/or because of engine icing (engine de-icing switch is not activated).

 

Hope it all works for you and have fun at 12K feet. :)
