"custom"...you wish

well… this hurts, but… are 3rd party devs messing with us???
While i´m writing this my Just Flight BAE 146 (failure enabled, “real” probability) sits at hte terminal in nzqn, at full thust and brakes set, waiting for an engine failure for 8 minutes. Don´t get me started on “why would you even?”
Let´s discuss that. How much is there really in terms of systems depth? Because if (e,g,) Leonardo says “our plane can be flown using the actual fcom” i think they know how hard it is to actually come by a real md8x fcom, in order to proof that statement…
i KNOW it´s just a game, but why would one even state things like that ?

(sad) regards

Why do you think an engine would fail after 8 minutes? Am I missing something?

So you think IRL an engine fails every 8 minutes?

Are you saying applying takeoff power for slightly longer than allowed in the POH won’t immediately blow the plane up to pieces? Impossible!

Yes. Thats exacetly what i’m saying.

The Leonardo MD-80 does it, btw. Exceeding EGT is no Joke, no matter wich Kind of engine we Talk about…

I was actually discribing the scenario. Given “real” meaning “real” Theres no way a 1989’s engine without EEC could sustain that without overtemping. Then again maybe my expectations are a littke bit Off. Simmer’s disease. It’s still a great plane though

‘Overtemping’ and completely failing are two different things.

I have never flown a 146 so don’t know, but doubt very much that even a non-fadec controlled engine would implode after 8 minutes at full thrust.

i´m at 20 minutes now. take a look at the TGT and the N2 values…

i now raised the OAT to 60, now i´m at 999 TGT and 120% n2

I am curious: while I am sure doing this is detrimental to the lifetime of the engine and therefore highly undesirable in real life, do you have a credible documented source that quantifies the harm? Is it proven in real life that the engine will fail within a short time of minutes if abused like this? Quite frankly, given the normal operating lifetime of thousands of hours for turbine engines, that sound extremely unlikely, but perhaps you have information that proves this?

From the Avro RJ FCOM

It’s stated that No more than 685 is allowed for any longer than 15 SECONDS. I think one can safely assume that after 20 minutes @ 999 degrees the Thing would have literally melted!

Ans as far as i am aware the RJ even Had an FADEC

That’s an operating limitation for the Flight Crew, not a ‘the engine will fail if you go beyond this’ hard limit.

Thanks. However, I think that assuming an immediate engine failure is risky. It actually might just mean that it starts causing a serious reduction in lifetime, like from 10,000 hours to 500. To each his own, but I personally would not dismiss the developer for something like this.

But whatever

That wasn´t my intention…I like the product but i just started asking myself, if those so called “study level” planes with all their “custom” systems actually have that much going on in the background , or if it´s all just marketing hogwash…
The Leonardo MD-82 CAN be failed btw when exceeding the Engine limitations for more than 20 seconds…

I really did not want to come across as being argumentative: I am truly curious as to what would happen in real life. It just “feels” (and we all know how much THAT is worth! :laughing:) weird that you could destroy a turbine engine in minutes by abusing it like this. It is very clear that it is a Very Bad Thing to do. It would just be great to get a definitive (engine manufacturer-type statement?) perspective as to what the short term/immediate and long term consequences would be.

Well let me tell you where i´m coming from:
Not rated on the 146 nor on ANY civil airliner BUT thinking about how my Toyota 100 HP diesel engine might not take running at full power in 1st gear for more than 15 minutes well, i just ASSUMED that there might be something off…
Fun fact: nobody knows what actually might happen in this scenario. Not even real world ATPs and that ´s okay, because its just a desktop sim.
But i just don´t like being BS´d.
Justflight said: “Now theres accurate failures for the 146”. After 15 hrs. with random failures @ “high” i have not had a single one. I bought it because i read that it now comes with random failures… then again it only was 65 Euros…
I posted in their forum to at least give an insight as to ho these mechanics work… I´ve yet to recive an answer

You aren’t getting replies because your comparison is ridiculous. Your 100 hp toyota diesel engine is not designed or rated to aviation airworthiness standards and, seeing as you’re not rated for ANY sort of aviation, maybe you should defer to developers who worked with actual pilots and, at times, the actual manufacturers of the aircraft instead of thinking the BAe 146 has engines that are as fragile as that of a 100 hp toyota diesel.

EGT and N1 overlimits aren’t even guaranteed to be warning events. Straight from Airbus’ safety article regarding EGT overlimit events:

Your stunt probably will reduce your engine life and bring your random failure earlier than usual, but that might mean 200 hours instead of 1000 hours, not 25 minutes.
