[27JULY20] Development Updates



Hello everyone, It's been a very busy few weeks! Over the last few weeks, we've released a moderately sized update for PACX (as it is nearly to version 1.0), we fixed a small snag in the TFDi Design 717's navigation display, and of course, have been hard at work on the TFDi Design MD-11. I've included some new renders and information from a few of the developers on the project.


To start, I'll quote @Ricardo Ramos, the systems programmer for this project.


Electrical system development is progressing fast: buses, generators, relays, switches, loads and overall interconnection mesh were coded individually and now are being integrated to work together. Buses share loads and sources when interconnected. Transformer-rectifiers and inverters were created with efficiency coefficients so when a load is present in a DC bus, the corresponding AC bus will be loaded proportionally to the transformation ratio and efficiency. Generators also share loads when interconnected. The overhead indicators were already added. Buttons event handling are coming next. With all parts working together, the logic for switching relays in automatic mode will be created and integrated last.



@ozzman1997 has been doing some incredible work on the model as well. The exterior is nearing completion (still pending texturing, of course), but the cockpit has progressed immensely.




Finally, I've been working on the FMC/MCDU (and its associated sensors, computers, and systems). I don't have a screenshot to show this time, as the majority of my work has been behind the scenes. That said, here are some key points of what's been added to the system recently:

  • Triple, independent IRU simulations with simulated drift and realistic alignment behavior (for example, a fast align can be performed once the IRU has captured true north and has been previously aligned).
  • The GNS systems are implemented and have the appropriate amount of sensors and information channels to integrate in a realistic way.
  • The navigation database system has been optimized and brought into the MD-11 and is now being properly read by the FMC, including both primary and secondary databases.

The next step is beginning to code flight planning and MCDU operations. Unlike our previous aircraft, we intend to simulate all (except maintenance/third-party software) features of the MCDU, such as wind entry and RTA. Of course, we're still early on, but progress so far bodes well.


That's all for now and thanks for reading!

I know its still early on but when BETA is avilable how do i sign up for future reference? 



We will make our selection and roadmap for beta publicly known in advance, but we are way too to say anything definitive now. Thank you for the interest, however!

First of all, GREAT WORK! I love your 717, and for sure will buy the MD-11 🙂

One question, i hope it's oke to ask.

Any change that maybe the 717 and the MD-11 will come to the new Microsoft ''Flightsimulator''?

I understand if you cannot give an answer yet, but if you can, great!

Will you folks include auto-step climb features as found on later MD-11 Aircraft?

Assuming we're able to find real world reference for it, it will likely be on the radar.

Our intent is to support MSFS2020, assuming it is capable of supporting the product. Without more SDK information, we cannot make an informed, final statement on it.

Hey Turbofan, if you check out Honeywell's site they go into the Step Climb differences between their legacy and the new NG systems they have. The MD-11 uses the Honeywell Pegasus FMC (FMS / FCC) which is the legacy variant that used what they called "Optimum Step Climb". Perf Pg 3 is where the crew would set the step climb altitude amount on the legacy models.


An account has to be registered to see the documentation but this is Honeywell's actual FMC Documentation library for all of their FMC's
