This is done to evaluate Flight Simulator 2004 for a potential integration into HIL (Hardware In the Loop architecture) architecture used in developing embedded systems on UAVs.

After a general presentation of the simulator and the reasons which lead us to study it, we describe the experimental procedure based on the definition of real-time simulation and Monte Carlo Method.

Experiments conducted in different configurations allowed to isolate parameters that have a decisive impact on the real-time performances of the simulator.

I. I NTRODUCTIO N ardware I n the Loop (HIL) simulation is a tech nique used for the d evelop ment, te sting a nd valid ation o f embedded s ys tems.

It involves a device that fools the embedded system under te st t hat o perates in real time, with real inputs and outp uts 1, when in f act it w orks w ith a virtual environ ment.

These advantages have pro moted HI L simulation to the ran k o f a standard o f development i n industries with hi gh stress such a s aviatio n and aerospace industry 2.

To b uild a HIL simulator, we must first imple ment the real- time plant simulation which is a mathematical representation of all dynamics included in the p lant system 2.

This approach is commonly used because it helps to build lo w-cost HI L plat forms with a cozy computing po wer and storage resources.

Other HIL architectures use COT S-FS o nly for visualization, like the one built at the Georgia inst itute of Technolo gy (Atlanta, USA) where the y used FlightGear 5, 6.

T his is done in order to integrate FS2 004 into a HIL architecture that will serve in the develop ment of a fixed- wing UAVs e mbedded systems.

The originality of o ur work is that unlike X-Plane a nd FlightGear, FS2 004 is not used in academic publicatio ns that treat of HI L s imulation, bec ause it is initially Ma n In t he Loop ( MIL) COTS-FS 7.

Adding to tha t, Micro soft d id not reveal technical details ab out its dynamic mod eling 8.

This pushes us to characterize it th rough experi ments using APIs (Applications Programming Interfaces) certified by Microsoft.

A general p resentation and r easons t hat cheer us to st udy this simulato r are listed in sectio n 2.

Sec tion 3 is dedicated to the description o f exper imental confi gurations co nducted on FS200 4.

T hese experi ments are based on t he defi nition of real-time simulation 9, 10 and Monte Carlo Method 1 1.

II. MICROSOFT FL IGHT SIMULATOR Microsoft Flight Simulator (MSFS) is a software marketed by Micro soft sinc e 1 982; the date o f apparitio n of its first version SUBLOGI C made by B ruce Art wick 1 2.

Since the n, it had kno wn a b ig develop ment in its d ynamic and graphic modeling.

Indeed, the latest vers ions: Cent ury of Flight (FS2004) and Flight S imulator X (FSX) ap peared in 2003 and 2006 respectively, are considered more as an immersive virt ual e nvironment ded icated to pilo ts training rather than video games (Fig.

In fact, t he U. S.

Na vy a nd the Fl ight Safety Internatio nal Academy (US A) use it for pilots training 7.

We chose to integrate FS2004 into HIL arc hitecture for the following reason s: Refere nce 13 asserts that FS 2004 is real-time.

Ho wever, we want to co nfirm that, espe cially since t he simulato r ru ns on a multitasking op erating system (Windo ws XP).

A simulation i s said real-time if its frame time i s sufficie ntly small, and t he co mputation i n an y frame ne ver exceed s t he frame time 9, 10.
