Hello,Since my last post got deleted I'll try and repost using my full name this time.... My question... Will the NGX feature a persistant damage model? At the moment my most add-ons are Marcel Feldes Katana 4x, A2A Spitfire and B17 and IRIS F-14 and that is only because they include a maintenance hangar, persistant damage modelling (and calculated damage/failures according to usage) and in the case of the Tomcat, compressor stalls. Are failures in the NGX done in the way they are in the MD-11 and previous PMDG products (random, timed and set) or are there new features ot look forward to? If the NGX can include things like compressor stalls, turbine flame-puts (when facing downwind upon start) and a 'maintenance hangar' which makes you 'take care' of your plane, then you certainly have my vote.... Also hydraulic leaks and burst tires from hard landings would be nice....*EDIT*Also I noticed on the customization video that you can set the brakes package.... so, in the spirit of this post, are brake fires modelled and thermodynamic laws respected?Regards,MJ O'Donnell

There's a realistic mean-time-between-failure model for everything in the plane that can be enabled in addition to timed, random and instantaneous failures. The model is based on the real life NG maintenance data.As we've said before on the engine start issue, we're not doing the kinds of things you mentioned because quite frankly they don't happen on modern high bypass turbofans with EECs - we tried as hard as we could in a real level-D simulator to get engine start problems to happen by intentionally abusing it, doing stuff with the wind like that etc, and we couldn't do it. All our real world crews have never had issues during start either - the CFM56-7B is an incredibly reliable engine. You'd have to have a totally unrealistic amount of airflow through the back of the engine to do anything to it like what you're asking about here really. Keep in mind too that someone who is in charge of maintaining real fleets at a major airline is a member of our team - if he says this stuff doesn't happen to these engines, you can take it to the bank, even without the sim testing and stuff.Engine compressor stalls are actually something I've already asked the programming team about - no guarantees but it would be cool, I agree.There's no physical "hangar" or anything like that for doing maintenance in, sorry. A modern airliner is not like a simple GA plane or an old warbird where you change some fluids and check tire pressure and stuff like that - it's a huge team of people (an entire department of the company in fact) who do airliner maintenance at real airlines. Please don't take this the wrong way - it's not because we're incapable of programming stuff like this or don't want to, it's just that the kinds of things that are actually done in airliner maintenance don't really make any sense for the pilot to be sitting there pretending to do. We do have to draw the line somewhere with this product - it's already an incredibly deep simulation of the systems of the airplane - everyone will see when it's released.There is a fully consistent thermodynamic model not only for the brakes, but for the cabin air, the wing duct air, the engine EGT and so on. Here's a fun failure - overheat the brakes on landing and then take right back off again and retract the gear. You now have a realistic chance of the heat soak from the brakes causing a wheel well fire. Our failures are all dynamic like this - one can cascade and lead to others, which is definitely not a common feature in FS addons. This isn't a simple "on/off" system like many addons do at all.

Thanks Ryan and PMDG staff for taking the time to turn a boring Monday into a wealth of information... Oh and send some sunshine back to CA... HA HA HA Take Care

Ryan, not that I set out trying to break my virtual aircraft (I generally fly with failures off - boring, I know), but in the instance highlighted above, would we see anything like flames/smoke? Just wondering.

Glad to see that pilots will finally realize the consequences of their own negligence

You're telling me I can't blast my 737 down the glide-slope at 450 knots with flaps 30, then bounce the aircraft down the runway with the parking-brake burning a hole into the concrete, all before I do a full-thrust taxi back to the gate in -300c temperatures while expecting the fuel in the tanks not to freeze?What type of simulation is this! If PMDG simulates fidelity of this magnitude I can assure you I'll be sticking to the default 737 where I don't have to worry about having my aeronautical pride crushed.(Disclaimer: The above was tongue-in-cheek humor. I'm joking. :( Way to go team. )

So, I was wondering how you enable/disable failures with the NGX. I'm assuming it's through the FMC (since we've been told that everything is operated in that little box).But my real question is: Will you be able to choose in the FMC which kind of failure you want? Let's say that one day I want to practice tons of failures and fires. Then another day I want it to be as realistic as possible to real life. Flying from A to B and expecting it to fail on me (or hopefully not) as it would in real life. For instance. Engine failure being "reasonable probable" 1/1000 to 1/100,000 probability, which according to my ATPL book says is unlikely to occur often but may occur several times during the life of the engine. (JAA defined probability). Then again some might even want to not have it break at all, so I guess you could turn it all of too? Thanks a lot!

It's fully configurable yes... MENU->PMDG OPTIONS->FAILURES is how you get to it.

Will the brake overheating actuate the tire-popping like in the real jets? By popping I mean intentional tire deflation

:LMAO:Only 450 knots? When I'm in the default 73, I can do a continuous-decent-approach from FL900 and easily hit mach 1. I don't know why youre such a whimp. Don't you realize that your passengers have connecting flights?!

This kind of "wear and tear" failure sounds really cool. Question, though. Ok, after X hours something fails because it is at the end of the useful life. Ideally, I would then complete the flight using some alternate systems, and then get said thing fixed. How is the "fixing" modeled? Do I just go into the FMS menu and find the offending part /system and click something like "fix", and it goes away or "defer" if I want to live with it? Sort of like, if I'm in a flight in the MD-11 and encounter a random severe failure, and I deal with it, but don't really feel like landing immediately as would be normal SOP, so you just go into the drop down menu and "cancel" the failure and continue? So, here, I assume, part breaks, and I can "fix it" in the air or on the ground using the FMS?

We missed one picture:No, it's not the same one that Vin posted a few weeks ago.

And gives automatic Failures?Jerome A.

door failiures? that will be interesting to play with.

will the wear and tear be accumulated?I mean... if i continuously rape the engine during the flight this afternoon (Running it until it reaches the red line, for 7 hours), and i land the bird normally... tomorrow when i launch fsx again, the ng will be brand new again? or it will be more likely to fail, because of my continuous abuses, rapes and orgies flight after flight?
