DCS: A-7E Development Update 2021

DCS: A-7E Development Update 2021

G'day Pilots,

Today we've got a small development update for you from the A-7E. Apologies that we've been quiet lately; we've had a few setbacks these last few months that have slowed us down slightly, but work has never stopped completely and progress continues to be made. Aside from that, we've also been polishing and tidying up our next (non DCS) module for release; more info on that to come soon.

Previously I've discussed our development plan for the A-7E and our intended phases of development. We can now happily report that we are elbow-deep into Phase 2, and making excellent progress so far. With the Flight Model making progress in leaps and bounds, we'll soon be turning our attention to avionics and systems development and integrating these with the previously developed core systems.

Today we'd like to ask your thoughts and feedback: In what condition do you prefer to see the cockpit in DCS? Dirty, worn and aged? Immaculate, fresh from the factory? Or somewhere in between? 




As you can see, 3D Art has continued to progress steadily, with some focus returning once again to the cockpit. Alex has been very busy experimenting with materials & photogrammetry, building texture sets, and painstakingly recreating panel and rivet lines. Work has begun on gauge and analogue avionics modelling, including some initial experimental lighting tests. These are all of course very much WIP and subject to change substantially throughout development.

Below are some WIP images including a photogrammetry test, texture demos and lighting tests.



Flight Model

We're very excited to say that our Phase 1 test EFM has been discarded, and we are now well underway building our first iteration of our full-fidelity A7E Flight Model. Our current model is exponentially more complex than our previous test build, and is built from real world wind-tunnel force, moment and derivative data for the A-7E. 

The FM so far is built from a combination of Stability & Control derivative tables (taken from real world data) and force/moment lookup tables to accurately capture the unique aerodynamic properties of the A7, including it's interesting spin and stall tendencies. Whilst the available data is comprehensive and suitable for a detailed simulation, we will be going the extra mile and investing heavily in Aerodynamics simulations & CFD software in order to extrapolate additional data, validate current data and validate additional parameters of our FM. In this way we can create a comprehensive aerodynamic database for the A-7E, cross-checking and validating data as we do so via CFD simulation and other means.

All this of course is a significant amount of work, and we expect work on the FM to be ongoing for many more months yet as we continue to develop the aircraft systems. With that said, we're extremely pleased with the current progress of the FM. So far we have met our development timeline targets and are confident we can produce an excellent FM.



Whilst todays update isn't quite as detailed as some of our others, we hope this bit of information is enough to help appease your appetite for A-7 news! 


Thank you all and have a great day,
FlyingIron Simulations

    I’m looking forward to the A-7E for DCS. For the cockpit weathering I would like 2 options, 1 for new and one for in-between.

    Hi the A-7E will be a welcome and interesting addition to DCS World. One thing that never gets mentioned is the potential of an in cockpit VR pilot model. It’s a some have some don’t mismatch in DCS right now. I am a VR user and once you use a module with an in cockpit pilot it becomes hard to use and enjoy a module without it. It is a feature that ED have tended to incorporate in most circumstances and if not already featured certainly planned for their modules. For some 3rd parties they have taken the time to include it and it’s a very well done and appreciated feature. For other 3rd party developers it doesn’t seem to be a priority or planned.
    I would like to know if you plan to add this to your module. Personally it would mean a lot to me and I know speaking to many in the forums I am not alone. Regards.

    Ideally synced to the age of the airframe . Ie early version are more pristine… say an 7e from the first year it was used … but maybe one towards the end of service would be a bit more worn. I don’t know if interior schemes are a thing like they are for exteriors…but if nothing else a bit clearer than the heat blur f14. Some of those labels are almost indecipherable.

    For the cockpit wearing, I would say that somewhere in between,so we can see your amazing work!!. That tail looks amazing.

  • Patrick Mussotte

    For the cockpit it would great to see some wear but not too much because sometimes it’s difficult to read the labels , IMO. Keep up the great work, for me this is a day one purchase, the SLUF rocks!
