suggesting to add a lot of vibrations and smart effects to translate the forces and help users interprete the immersive experience, what otherwise is simple theory. i wanna see Austin buying a ticket to TelAviv, sit into that F4 and get the wildest ride of his life, while writing vibration and living forces code, the sound lady at the ready.

I always love to listen to (or read) Austin’s thoughts about X-Plane development. He can transmit his pasison very easily and makes the ride very entertaining. It’s really amazing how X-Plane moves from “tuning it to feel like real” to drop the naked aircraft in the world, notice the emergent behavior and fine tune the world.

The flight model and the weather engine are acting like a big neural network. Austin is throwing aircraft to them and train them to treat these aircraft realistically. This has the benefit of bringing more simplicity in 3rd party aircraft developers and also it propagates benefits to the entire fleet from every single fine tuning.

Congratulations on this amazing work and thank you for sharing the knowledge with us.

The drawing skills of that artist in the Air Force training video taught me more about AOA than any bird or bee ever could! 🙂

Great article!

So exited for XP12.

How does the stall work on the F-4? In XP11 it stalls if I pull up too much. Is that going to be more accurate in the new version of X-Plane?

In reply to Austin Meyer. The right tool for the job, eh? ;-)

Great development for sure….it’s great to know how accurate X-plane engine is becoming.
Thanks for sharing Ben

Bravo !! Real life is the test of a high fidelity simulation… if you put in the real numbers you get the right result, but only if your model is refined enough to capture nuances to this level of detail …. and it’s how the real world works … balancing all those tensions in real time !! Bravo again Sir !

For an encore , please do a squirrel suit !!!!! 🙂 j/k … can’t say how much i loved reading this !!

And this is why X-Plane is a real flight sim and that other popular one is a game. Great work! Looking forward to try the improved dynamics in X-Plane 12!

In reply to Michael Bonar. I code the flight model myself. Every single line of code referenced above was written by me, personally. My only help was constant interaction with the F-4 pilot with a constant flow of information on how the real F-4 flies. Other people at LR do other stuff in X-Plane. I exclusively do the flight model.

Really nice article! I learned so much! Can’t wait for XP12!

PS. Does Austin really code it all by himself? Or does he need to practice saying “we” more. 😉
