Well, another thread on flight models for those interested (for those not interested in FM discussions, just move beyond :smile: )

 

I recently tried Aerofly FS. If I remember correctly, in the past it has been praised by RW pilots on these forums, for giving a realistic sensation of flight.

 

Well, I tried the various aircrafts of Aerofly FS (with joystick sensitivity to max, that should give a realistic max control deflection), and the general sensation I get is that its flight models are more similar, I'd say significant more similar (in their feeling) to those of X-Plane rather than FSX.

 

Unfortunately there are no twins on Aerofly FS, but e.g. the C172 is not particularly stable on the roll axis, indeed the X-Plane C172 looks to me more stable than Aerofly FS's C172.

 

Does anybody else tried Aerofly FS comparing it to X-Plane and FSX?

I did, up until the latest beta which was available at Steam a couple of months ago and now went final.

 

It's a nice sim, and I second your opinion but, particlularly regarding the two gliders. both have stall chracteristics (specially the Discus) and overall handling not very realistic IMO.

The prop aircraft suffer from the same torque roll instead of slipstream yaw problem of most sims, although they're not plagued by the irritating persistent torque roll of XP's prop aircraft. The stall characteristics of the Cessna and Robin leave a bit to be desired - as you pointed out, way to much roll axis instabiltiy...

 

There is a good free add on ASH-31 - read about it here and get it here It performs a lot better than the default Disbus bM!

 

I like the winds and turbulence models, specially turbulence connected to orography. The thermal model is way simplistic, but better than the allways "straight-up" one in XP10...

Yes, 172s are very stable. I remember some quick roll imputs for the purpose of comparing to flight simulation. I'd quickly move the yoke to the left, and then let go. The plane would roll left, back to the right a bit past level, and then level out. That is quite different from my low wing (more fighter feel) RV, which just stays to the left for a bit of time, when letting go of the stick.

In at least one thing I have to take my hat off again for Aerofly FS... The torque roll physics!

 

Man, the Extra, the Pitts, all of the prop aircraft do show torque roll, and faint, if any, yaw due to slipstream, but it (the torque roll) ends soon after power is changed, just like some text books explain that, appart from some very powerful prop aircraft, it is supposed to be the case in RL.

 

Yesterday I made some extensive testing of Aerofly FS again. I confirm the correct modelling of negative speeds and corresponding control reversal, and also the fact that a good model can give you excellent / realistic performances. The free add-on ASH31 SLG performs a lot better than the default Discus bM, and the author explains what he did to achieve that performance.

 

The AeroflyFS "airfiles" are text-based and can be easily edited...
