AV-8B Harrier Thread

Calm down guys, I'm not attacking or bashing anyone here, just asking a question.

Basic HUD is almost ready. Only thing left is the heading tape.

 

This is the basic NAV mode HUD. It provides the following information:

 

Indicated Air Speed (Knots),

Altitude (Barometric or Radar),

Angle Of Attack,

Mach number,

Aircraft Gs,

Ground Speed (Knots),

Max attained G,

Vertical Velocity (feet per minute),

Auxiliary heading reading (True or magnetic. Default is True).

Zeus,

 

Is the flight model the toughest challenge you guys had thus far, out of all of projects for DCSW and other sims? :)

[fastfreddie]

Which is totally uncalled for and not necessary. Some people just don't understand WIP and that frustrates me.

... and thats how we end up with devs that quit showing us WIP like VEAO. If you see a video thats going Beta in 2 weeks it would be one thing to mention it but otherwise quit complaining.

[joey45]

I think I accidentally opened the wrong can....

Looking great, can't wait.

I made a ramp a couple years back to test some planes, would be great to use it with this.

You are loosing your time, it's useless...you cant do any kind of contructive criticism in this forums without being bashed. I just made a gentle observation about a WIP project (so, on time before release) and thus, before its too late to do it (m2000) but of course, instead of even think about what I said (which I find quite reasonable) I just dont understand what wip is, Im bashing devs, Im the anticrist,etc.

[joey45]

Okey that's it... Let's not open this can of worms even more...

[Ells228]

Looking excellent, can't wait to fly this one!!

Always been a wish of mine to fly a Harrier in DCS :)

Lets not get out of line..we do like constructive criticism, the main reason we post "WiP's" (Work in Progress) pics, and always open to changes.

But what needs to be kept under consideration is that these are early renditions

Looking great guys! Cannot wait for the Harrier!

 

Also, who is going to be the first developer to do a quick inside look live stream at what goes into coding an FM in DCS? Now that would be cool and interesting I think, just a quick overview would be good, something not too heavy tho.

With a date!

I've heard from numerous devs how the FM is structured (ie every part of the plane gets its own flight model) but none of them have ever shown the actual code involved. I'd love to see a few dozen lines of the FM code from the Mirage, or any plane for that matter. (You can't do this in the game files because the FM's are compiled)

[al531246]

I believe some of the software / methods used to create the aircraft is behind closed doors, the dev must sign an NDA to use it. I don't know if any of that is used to create a FM but if it is you won't find any sneak peaks being released. Although I could be wrong, this is just the word on the street!

[Pocket Sized]

The exact methods used for coding an EFM are up to the developer. (Hence external flight model) This is why the quality and feel of EFM's varies so much.

It's Looking Good Guys Keep Up The Awesome Work

Quite sure DCS is pretty much an open canvas for 3rd party developers from what Ive heard, except for things like radio code and the like to tie into DCSW, other than that you can choose how to go about things. DCS must be worlds apart for RAZBAM that was limited to the FSX model, Except now much more work seeing that it's lot more accurate. Could only imagine the work involved that has gone into getting the Harrier into DCS compared to the other sim.

To be short, AFM is built from the ground up. We don't build behaviors to match desired performance. We build a physical model as correctly as possible and then check it against known performance characteristics. If the model is built correctly, it should match the performance characteristics closely by itself without requiring any "top-down" scripting to do so. Of course some miscalculations or oversimplifications or just plain errors happen along the way, so testing, tuning and adjusting is always necessary.

Hence the long understandable beta's at this level of simulation.

 

Anyway getting a little off topic here, just posted this if anyone's interested.

Good find David OC. :thumbup:

[CapableJet7]

But why the Night Version of Harrier and not the Plus II?

Everytime I read so many questions that have already been answered in this thread.

Very interesting, thanks!

Looks great! Can't wait to learn this!

[joey45]

I will like to apologise to ED and other 3rd party devs in advance for neglecting their modules when this gets released.

[comie1]

Hey Raven! You'd be surprised how straightforward it actually is. I've taken a ton of lessons from our first go around with the M-2000C which GREATLY accelerates the development process for the EFM. To add to it, there are numerous research reports on the AV-8 family of aircraft so I'm super happy there is much more data to be able to start with than with our first project.

 

The other thing that is great, is that the EFM interface is just a way for us to send forces, moments, inertias, and weights to the sim. Which are the most basic ingredients for modeling a moving object. What the means is we have full control over the entire way the aircraft moves without compromise. The great advantage comes with the easy of modeling thrust vectoring as well as the reaction control thrusters. We can just direct the force or moment where and how we want with no gimmicks.

 

----------------------------------

 

I also noticed some of you asked to see how an EFM is made. The best thing I can suggest is take a look at the F-16 example I made years ago when getting started:

 

https://forums.eagle.ru/showthread.php?t=95985

 

It's not the best example and shows a different approach than the one I took for the AV-8 and the M-2000C but the idea is the same.

 

I'll update the title post of that to provide a link to RagnarDa (the amazing FM developer of the Viggen) who took my original download and fixed up many of the errors in the code and added some features. That should give you a good idea how it's done.
