Thanks for link Taufic, Austin is my new friend :). stall features being optimized and quite a few things too. 

 

Clouds getting optimized

Thank you!

 

The developer blog is public. I like their openness. X-Plane is different!

What I like: "New view option: Lock to point. Lock onto any spot on the ground and you TRACK it! Nice for VFR pattern, etc.". It's a cool feature.

I'm wondering how these changes to the PT6 turboprop will affect v10 planes with those engines. The more accurate modeling sounds great, but will it affect normal flight operations in any major way for a plane built for XP10?

 

So far, I haven't noticed anything yet when flying a few v10 planes with those engines in the XP11 beta, but I usually start hot on the runway and don't spend much time fine-tuning prop pitch/fuel flow beyond just a basic cruise setting. Maybe the new modeling doesn't apply to planes saved in the v10 Planemaker.

 

The rotor improvements are interesting. Mast bump, yes! I just hope if Austin has been tweaking "settling with power" and VRS that he isn't making it kick in too aggressively.

I don't see your comments in the blog

 

Probably because its awaiting moderation.

Confirmed, awaiting moderation - I can't see them either :-)

I was surprised to hear him mention "objected oriented" programming. I just assumed this was a common approach in the gaming industry. It is at least for general application development.  Good news indeed!

In other words everything now is polymorphic, dynamically bound, and encapsulated :)

Who knows, everything may be statically bound :) Maybe we should see some of the snippets before we draw any conclusion.

Clouds FPS improvement during the 11.00 run. Good!

Great - clouds murder my fps at the moment

Read the link. All good stuff!  Nice to have a turbine aircraft handy, when programming reality.

Funny, looks like every single comment is someone requesting a different feature lol. Can't make everyone happy.

Some of the items mentioned by Austin have already been included in the latest beta(s), like the tyre model and the loss of effectivity of control surfaces in near stall AoA.

 

The Pt-6 modeling still presents the fuel flow bug from previous versions though.

 

Welcomed are the aditional types of icing effects on static and dynamic ports and the effects of accumulated ice on stall AoA.

 

In Ben's Blog I wrote about the weathervane effects and the possibility of adopting a Perpetual Calendar so that we can specify the full date for a flight, and possibly get correct daylight at any place and time :-) and... you know what more too....

 

But for me, what Austin wrote is at least indicative of his concern ( at last! ) to look into X-Plane's fight and systems modelling along the XP11 run, and some of the mentioned features will make it an even better alternative to other civil flightsims, and an even better choice for procedural training.

 

I will be following XP11 very close, every day :-) here at AVSIM and at Ben's blog, and strongly hope for the best ...

These are a welcome changes , though i have not tried to stall in the 172 and get her in a spin as yet. Quite a few of those things mentioned are a bit complicated to understand though. 

 

That stupid tyre screech still seems to be there . anyone ? 

 

Though i like the shock compression modeled now in the cessna quite cool.

 

Hopefully they get the rendering optimized now.

It is great that xplane is constantly being improved but this link highlights one of the weaknesses of xplane too. Because it is owned and directed by one man it means the direction it takes is entirely due to his interests at any given time.

 

That article is a prime example. He gets enthusiastic and talks about how he is fine tuning the turbine model due to spending more time in his aircraft. He enthuses about how he correctly tweaked the fuel flow on the cirrus and Columbia, again due to his ownership and experience in those aircraft. Great if those are what you want or like.

 

Unfortunately he gets distracted and enthusiastic about the minutiae of these things which on the one hand I think is great(I am a massive nerd when it come to technical details and accuracy) but on the other hand is really annoying when he writes a post about how he is improving the accuracy of the sim and how real it feels and yet ignores the fact that a 5kt cross wind will blow you off the runway....

It seems the basic dynamics are having to be solved by the community. Thanks Murmur!

 

I just wish he would sort the basics first before devoting his time to the icing on the cake.

Well, there is a huge difference between the start of X-Plane 10 and today.

In the past days developershad to tweak their aerodynamic models to somehow counter these effects. Today they simply override it.

Yes there is a huge difference between the start of 10 and the end, yet those simple bugs still exist. I just wish he would fix the basics which have existed all through the development of 10 and yet have been ignored.

He gets excited and runs off looking at specific details that interest him at a certain point in time and yet won't fix something that has been around for ages. It's frustrating! Like I said before, I love the advanced stuff but I want the simple stuff to work first.

I think we should all take up a collection, and buy Austin a vacation cabin up in the Pacific Northwest near an airstrip. Maybe northern Vancouver Island somewhere. Make it so the cabin is only available from November to January. 

 

Then we'd probably get that weathervaning issue solved.

 

Next step, a place available only summer, somewhere with a lot of thunderstorm activity and an airstrip, Maybe the Midwest or South Florida. Then we could hope for more accurate CB's and a full 3D weather model.
