Is engine icing modeled in the NGX?

Hallo Jack,As soon as you will notice a weight, AOA or drag change you probably will also notice that a movement of the yoke won't result in the same action as without ice. This is not a reason of a frozen controll surface, no it is a reason because of changed airflow over the wing. When you are flying it is quiet uncommen that a controll surface will be affected by ice. May it would if you spend enought time in icing conditions, however you can't do that because you will have fallen out of the sky at such a point.This pic shows where the ice will grow, and where it probably won't:This is one of the reasons why only the front edge of the wing is covered by ice protection systems, because only there will be ice.The ice changes the airflow over the wing and so you will notice a change in your controll inputs and what the plane does probably before or at the same time as you notice that your weigth, drag and lift has changed. So if ice would be simulated also change of the controls should be simulated. However, I understand that you won't be able to simulate this in FSX.Jonathan

Thanks for your post Jonathan,What you are describing would effect the critical angle of attack, parasitic and induced drag, weight and static lift.Thanks for the informative post. Nice drawing.JB

Is engine icing modeled in the NGX?

With engine anti icing on no. With it off, I don't think so, or I haven't seen anything to indicate it is modeled.JB

I tried the Ice gauge out on the default cessna in severe icing and freezing rain. Accumulation rate was slow, but it did do what the author said it would do. I flew circles in the weather for about 5 minutes, enough time to get the gauge to turn red with AFSD indicating an "Ice Weight" of 20 lbs. I noticed a decrease in lift, requiring a higher angle of attack and an increase in drag. Kept the ice on the plane until I landed where the approach and landing needed quite a bit more throttle to stay on normal approach speed.Unfortunately, since the gauge seems like it has a fixed accumulation rate and doesn't increase rate for more surface area (larger aircraft) then I think to get to just 1% of the NGX's Empty weight would take a lifetime.Ohh well.JB

Is engine icing modeled in the NGX?

Read a little more carefully. The question was asked and the answer is no. Ryan is fully aware of what the limitations are and if he says it can't be modeled realistically, then it can't. If anyone knows what the limitations are it would be PMDG. They broke just about every rule, barrier and limitation in FSX in designing the NGX.

The J41 does simulate it visually but it doesn't affect the flight model - simulating what icing actually does to a large airplane is outside the scope of what FSX is capable of I'm afraid.A 737NG is not going to be seriously affected by icing in real life unless you fly headlong into a thunderstorm anyway. The antiice systems are very good (much better than the boots on a turboprop or other small plane).

Thanks for your reply Paul,Every Possible limitation?JB

I will switch to PSX when it is done

What's PSX?

Ryan could explain it better, maybe I didnt use the right words. But there was a thread on this a long time ago where they explained that they pretty much maxed out what could be done in the NGX before running up against a wall or barrier. I can't seem to find the post right now but im sure somebody has a link.

I see,Thanks for the insight :)JB

Outa curiosity, does anyone here know how to read and write code for an XML file? And if so, with the above mentioned Icing gauge, can that xml be edited to largely increase the "Ice Weight" acumulation rate to make it more suitable for larger aircraft?JB

I know about other, very highly advanced FSX addons have infact simulated engine icing. Surely it would be possible in the NGX as well

Not to the extent of visuals or gradual engine power loss, but I believe FSCaptain does it.

- The "Hazard Package" is included which will detect certain dangerous conditions and make the consequences realistic in ways that Flight Simulator failed to do. Specifically, wet or icy runways and taxiways are now slippery. Icing can flameout a jet engine. Thunderstorms can now invoke extreme turbulence. None of these will happen without warning from either Dispatch or your First Officer, or both. The runway conditions are invoked from the reported weather in your Weather Source and may or may not match the visuals in FS. Thunderstorms and engine icing are detected from present conditions and should match the visuals. A new section of the "Weather Options" dialog available from the Options for All Airlines in the Administrator will allow you to switch these danger enhancements on or off. They are ON by default.

Why can't you just accept the answer is No? This is just like the Weather Gauge thing. They told you it couldn't be realistically simulated so they are not gonna make one. So now they tell you the same thing about icing but your gonna debate it even when they told you no again? Even if they decided to try an simulate it, they probably couldnt do it anyway cause they at or near the texture and animations limit. Most importantly it would be unrealistic which is why the weather gauge is not there, and the texture and animations limit is probably the reason for the 2d throttle panel not being there, in addition to the performance issue.

Just a sidenote, I took a look at the icing gauge which was mentioned earlier. Found out it is in fact created by the same person who developed FSCaptain (which simulates engine icing).

Have you used FS Captain and if so, how's the simulated structural icing?Sent from my iPhone using TapatalkJB
