Aerodynamic model

[paulw10]

I’ve heard it said from some real pilots that the acceleration and deceleration rates are noticeably slower than in the real world. Is this true, and can it be made closer? I’m keen to have an experience as close as possible to real world.

Which module do you mean by that? I'm quite sure, not all modules are wrong. On what data do those real pilots rely? Just a feeling? I don't think ED will change their modules based on that.

Real pilots? ... that doesn't says much, they could be Piper pilots for all we know. DCs developers consult with SME (subject matter experts) that really know each specific aircraft, so I trust them more than what an unnamed pilot may say.

If real pilots have hard numbers I would believe it. If it's a feeling I would disregard. Not because they wouldn't know, but because their experience is in a completely different environment. One in which an acceleration or deceleration is actually felt in the pants. Something that is missing in our fixed-base sims.

This came up in another recent thread...  IIRC the OP was an airline or civil pilot and also had friends in the Armée de l’Air.

 

The gist was that at low levels, speeds in DCS felt about half what they do in RL, eg, downwind leg in the pattern or low level tactical flying.

 

there was a fair bit of the normal “DCS numbers are right, anything else is heresy” type comments - but there seemed to be a few applicable observations regarding sense or perception of speed:

- terrain detail and object density are much higher IRL, and give higher sense of speed close to the ground

- sound, vibration and movement senses all feed our speed perception and are either absent or in isolation in a sim. Nobody could mistake a take off or landing from an airliner cabin, even without visual clues

I’m not in any way saying DCS is wrong. I think some ex F/A-18 crews have sometimes mentioned in online teaching articles that the aircraft seems to lose and gain energy a bit slower than expected. I’ve been researching BVR and ACM techniques and come across it. Might just be rose tinted spectacles though. Maybe they can’t really remember how it really flew. But I’m interested to know that the flight model is close to the real thing. Don’t think I’ll get to try it for real, so I’ve no reference point to judge for myself.

You can read any of the hundreds of threads around here discussing performance and behavior of the various aircraft, typically people will drag out performance charts and compare them to ingame results. You can also perform those same sort of tests yourself, if you really want to. It's time consuming but not terribly difficult if you want to give it a crack.

 

 Otherwise, there's always somebody going to complain and many of them will appeal to authority they may or may not have while leveraging facts and beliefs that may or may not be true. If you want to know, read the threads. Search is somewhere along the top of your screen.

 

 Generally the ingame aircraft are plus or minus a few percent in any given envelope. One of the more openly debated is the A-10 which does indeed appear to be underpowered although this seems more related to a quirk with ambient temperature rather than the plane itself.

 

  As far as ''close as possible'', they make an effort to do so. That said, it's still a video game, not real life and countless compromises are made both in simulation and in aircraft systems. It is not 100% accurate and never will be. Keep your expectations appropriate.

In regards to the A10, there was a longstanding issue with drag that was resolved with the release of the A10C II (also resolved for A10A and A10C as they share the same flight model). I assume this was the issue you were referring to.

  That was about the pylons, wasn't it? I thought somebody had determined there was an engine power issue related to ambient temperature and they performed as expected if it was set to very cold temps?

 

  I dunno, I don't fly A-10s so don't keep up on the them so much, just what I remembered o7
