Home computating power is not the real limiter for flight Sim.
Think that your FM does not hve to compute how your plane will behave to any kind of solicitation. Most of the Maths are done once for all B4 you release your FM.

For example if I want to simulate flight buffeting on low level flight at high speed I won't hve to actually calculate for each image projected on the screen how my ctrl surface will behave and than what wld be the amplitude of the plane then pilot head shaking !! An average non harmonic solicitation will do the trick

Good Phy and Math are essential to hve a nice FM. But an overall comprehension of what you hev to look too or generally speaking a comprehension of the flight phenomenas (and I didn't say "sciences") is of utmost importance.

Years ago Engineers where computing real FM with computers that had the power of a today pocket calculator. Nowadays a millions more power is used at every steps of the process by any one in the dev chain (thx to CAO requirements)... And we don't do better planes (F35/Typhoon/A400M etc...)

erm... it is actually. There is virtually no limit to the intricateness of a flight model, but it will need more and more computing power. You could build a CAD model of a Spitfire and simulate fatigue on each single screw if you wanted to, but it will need a lot of computing power.

I'm sorry but I don't think you have a full understanding of the topic man, or if you do, your explanation is ridden with generalisations.

Engineers don't calculate flight models, a flight model, even when accurate, is an approximation used for simulators. To design a plane you can render in CAD the surface and structure and calculate loads or aerodynamic coefficients, but you will still need to build and test prototypes.

Dear SternJ,

I am sry but you didn't took the train on time. See bellow post of Vip to understand that I was talking abt tweaking to simulate complicated probs.

Moreover it's over insupportable to hve to read on each of your post basically the "You don"t know as your are not this or that and blablabla"

Firsty I have reasonable confidence of my knowledge and I am always pls to learn/re-learn new things
Secondly I am debating here with all the people that are enjoying on this forum a new sim that is a step further toward our expectation regarding realism. I am not talking to you abt myself, you or my own lovely stern.

Pls open up and be alert and positive

no man, I'm really trying to be nice, but you were talking baloney.. and fair enough, it's not like we can know everything about everything, but if there's a topic you don't have a complete understanding of, just don't give statements like that, because people like me, who are driven by a particularly pedantic nature, won't like it.. it's for the sake of science really..
