Engine explodes on takeoff

[RazorTM]

My SU-25T engines frequently explode on takeoff with no explanation. Mostly happens at the Gudauta airfield, but I have had it happen on other airfields, too, but rarely, and I forgot to save the track files. This is killing me because it puts me a whole step back on the campaign every time :doh:

 

Two track files attached.

 

 

By the way, the nose wheel/tire is still insanely weak and blows if I even think of steering the plane beyond taxi speed...

What is your bird strike setting at?

 

If it is maxed out this will happen all the time, I'd say 30-35% of my take offs ended with an engine fire/bird strike when that setting was maxed.

I didn't even know there was such a setting :huh: Let me go check...

[RazorTM]

OK, there was a "Birds" slider set to maximum (1000). I set it to zero. So... I should hopefully no longer have this problem?

 

You'd think that the birds would actually be visible.......

[Devrim]

They're not visible animals. They exist as a posibility or chance in DCS. :D

I believe you will no longer encounter this problem.

Yup, at zero you won't, but I'd say keep it around 100/200 to keep things interesting. I have mine set at 500 just because I like to practice if I remember the emergency procedures. Even at 500 I only get an engine fire on take off about once every 25/30 takeoffs.

 

Like Devrim said, they are not visible, although in 2.0 they are visible above bodies of water but not sure if those are able to cause problems.

These are just a few seagulls, they have nothing to do with the birdstrike settings nor can they cause one.

Nope, I will keep the slider at zero. Now, if the birds are real, physical objects in the simulated world that I have a chance of seeing and avoiding, then I would turn the slider up a little bit for some "realism," but the setting as it is is just stupid.

that I have a chance of seeing and avoiding

 

That luxury you don't even have in reality. If you see a bird near your nose it's too late, you either missed it or one of your engines digestet one. ;)

 

The sliders standard setting seems to be at a reasonable level. Would be interesting to know the used probability at 100.

 

Real life values are around 5-10 damaged engines per 10.000 flights, in around 87% of the noticed bird strike cases nothing even happens to the engine.

Yes, I understand that, but when the bird is not visible/doesn't exist physically, you can't even take any action whatsoever to avoid it, i.e. delaying rotation/aborting/etc. I have a private pilot license and I work as a controller at an FAA control tower, so I'm well aware of birds.

[Sid6dot7]

When we have a better ATC, I could imagine a advisory note to you about a heightened strike probability and that actions are taken to get the flock away from the airport, so you can delay your takeoff/abort approach.

 

Visually representing this probability through flocks and single birds would certainly be difficult (especially swarm AI, network sync). But as said, in most cases the birds aren't seen anyway.

That is the realism part. You can't avoid a "bird strike"! Either there are birds in the flight path or not.

If they are, you are either lucky or you happen to have a bird strike... though I have to admit, i also set it to Zero, as well as "Random Failures" to off for convenience.

 

But the modeling is not "unrealistic". Usually pilots don't see the bird at all, unless it is a larger flock of birds. This usually would cause a shutdown of the airport/departure zone until the birds can be scared away.:D

I've avoided a bird strike before by delaying my rotation for an egret crossing above the runway at 50' AGL before. Not all bird strikes are unavoidable.

[Phantom_Mark]

I love this feature, I got it at 400, had a couple of strikes in maybe 100hrs flying.....the last time was heavy with the A10C, was just rotating when bang, stb engine went, training kicked in and recovered the aircraft no issues, but made me smile when wondering wtf just happened :D

[Devrim]

At the end of this discussion, I think we can demand a first-person DCS: Bird module. :P

 

Aah, I make bad jokes while drinking beer! :(

Exception to the rule... ;) I admit visual birds would be cool, but the challenge to "evade" bird strikes on a regular basis? That would be more "DCS bird strike simulator".

 

Most strikes I heard or read of, were virtually unavoidable. A flock of birds landing, or mostly single birds that pilots noticed split seconds before they ran through the engines... And mostly without major damage to the blades. :)

It's a good job we don't have simulated smells in the sim. Have you ever caught a whiff of what a seagull stinks like after it has splattered itself on or in a jet fighter?

 

Whoa.... hot fishy chicken! : /

engine fire

 

My bird slider is 0. However im still getting engines exploding on takeoff

[discwalker]

And your throttle is at IDLE position in the whole engine starting process?? Please make a TRACK if you still expreience the issue. Please with rightCTRL+ENTER: axes view in cockpit.
