Hello All. This post will be locked as its only intended for public statement. While many people are aware of the IXEG Development status, many others will not and so this post is intended to provide clarifying information. For a while now, IXEG development has sat relatively idle. The reasons for this are multiple and have been stated in other forums; however, two significant factors contributing to that idleness have since wained and IXEG are looking at how to best move forward with IXEG updates again. There are two areas we are looking at for updates, 3D cabin/doors/animations and the FMS. Regarding the FMS, IXEG are looking at transitioning to the XP1100 Navdata format, which is derived from the ARINC 424 standard. Moving to this dataset format would yield increased accuracy in the representation of procedures and more practical data with which to improve LNAV / VNAV / performance caclulations. If it turns out that porting our code to the new XP1100 format is too cumbersome in the short term, then we will seek to patch what we have now and transition at a later time. The important thing is that IXEG are moving again to improve the FMS. Regarding the 3D, this will be a bit more of a undertaking. The development tools IXEG used for 3D development are nearly fully deprecated and there has been a major transition to newer tools and methods. This necessitates IXEG reconfigure our source material to the new formats and we have a LOT of 3D material to translate. This means that the 3D updates will be longer in coming than the FMS updates. Once the 3D is ported to the new tools though, any updates we implement thereafter would come much quicker, simliar to what was done shortly after our release for those that recall. We apologize for the idle time and appreciate all our customers and any patience you've exercised. We are sincerely committed to making the most immersive and accurate simulation of this aircraft as we can and will continue to push towards that goal, no matter where its end may be. -Tom Kyler

Today we're proud to announce we have released the Beechcraft Sundowner version 2! Comparing it to our previous version of the Sundowner from 2009, this is a completely new product. It features things such as Reality XP GNS integration, Avitab, use of the particle system, completely new 3D model and textures, FMOD sounds, and more! Upgrade for previous owners If you were an owner of v1 of the Sundowner we are extending a special 35% discount to you. This discount offer will come to your e-mail, and is only valid for 30 days from today. A preview video is now available here: The product page is here: http://www.x-aviation.com/catalog/product_info.php/beechcraft-sundowner-c23-p-166

Sundowner v2 has now been released!

Neat little plane! Nice work team LES~

It works well in the current version of XP. As with all aircraft there are things that can be done to make them look and work better, but if you just want to enjoy a high quality flying experience with XP, then this is the model in my opinion. I would like to see the FMC fully functional as I find it can cause problems if adjusted in flight, particularly VNAV, but I usually work around those problems. Progress on updates is agonisingly slow unfortunately, but the developers are working on it and have advised that they will keep it going as XP is developed further. I know it is expensive, but you get what you pay for. I would recommend that you buy it sooner rather than later. Cheers

I would assume you are on windows. Go to windows defender settings and -add- a -folder- exemption for the entire /x-plane (make sure to add a /xplane folder not just file exemption) Problem is when you make a change inflight, scripts are loaded and updated real time until you commit the change via the EXEC button on the FMC, under that time the defender analyzes the scripts and cpu goes to 100% killing the sim performance.

Great! Going to try that! Thank you very much

So its been a while, time for another update. There was a pause after the rush of FMS work mentioned above. During this pause, I have finished up my NASA obligations...and demobilized from Houston back to San Antonio, where I live, and some much needed stability to my schedule. Last week, I dug back into the FMS code and started coding up the route editing features using the new XP1100 dataset. This is the backbone of the FMS future with regards to performance.....for VNAV calculations, performance progress and also holds. Its one of those things that I wanted to be real sure I was ready to dig into before doing so. This route editing coding will go on for a bit......'route editing' involves building the route data that the FMS will use during lnav and vnav tracking and so is critical to be flexible and correct. It is my belief that if carefully done now, the FMS will be functional and stable for many years to come, which is the most important thing. -TomK

Hello again. I'd like to give another update. During our investigation into updating our NavData to the XP1100 format, it became apparent that this must be the way to go for long-term future compatibility and more reliable route calculations, including holds, but would require a significant rewrite of the FMS base architecture to do so. So over the last 4 weeks, we have done exactly that. We now have the beginnings of a 2nd FMS running in parallel with... but independently of.... our original FMS. We are running 'newFMS' on CDU1 and 'oldFMS' on CDU2. We will NOT be simulating dual FMCs though. This old/new arrangement only exists so we can compare the new with the old while developing the new. It is much like building a new bridge alongside an old bridge...and when the new one is ready, we will remove the old. Much of the challenges we have faced with regards to drawing routes / vnav have been related to the limited nature of the navData format we have used since we began the project. Moving to a format which have been designed expressly for "navigation processing" will go a long way towards easing our algorithm development. The image below shows the two CDUs, both on the "IDENT" page, but clearly displaying differing data as they use differing algorithms/databases....and for those curious, the pilot CDU displays 'odd' formatting simply because we were testing our new display drawing code. We are very excited moving to this new XP1100 format. We have, in 4 weeks, accomplished what took us over 24 months to accomplish originally. Of course we have the benefit of experience, but the elegance and efficiency of the new navData format and architecture allow us to focus on the FMS functionality by orders of magnitude more than before. With the new infrastructure complete, we will begin working on the route editing. The current navData set only supports about 8 different waypoint types. Arcs are not supported, as is common in today's RNAV procedures, but the new format contains all path/terminator types typical in today's procedures. As usual, we thank you for any patience you have managed to muster as we work to improve the IXEG 733. P.S. Jan and myself will be at Flight Sim Expo in Orlando, FL/USA in a few weeks if anyone wants to talk shop. -Tom Kyler
