The other day (during a particularly uneventful flight) I was looking at the flight plan and in particular the TC and TD entries. It made me wonder what rates of climb and rates of descent the FMC uses to calculate such flight plan entries. Does anyone know? I had a quick skim through the manual but did not spot anything referencing this, or did I miss it? A quick calculation for the step climb changes yielded a rate of climb of 700 but not sure how accurate this is. Regards Stuart

Hiya Sorry not to have replied sooner but I have been a little busy and not able to get near my pc for FSX purposes for a while. I was getting this on every start up, so having read your post I just backed-up all my aircraft files and completely re-installed Linda. That seems to have solved the problem. Not sure how or why but some corruption must have crept in somewhere. Thanks and Regards Stuart

Hey Folks Can anyone help me track this error down, see pic? For months and months and months been using Linda no problem, suddenly this happens on start up of FSX. No, I have not added anything recently or made any other changes in the past few months. However, I did get a "fatal error" a few trips ago, which required a restart of FSX. I have pasted across a "new copy" of the linda.exe file to the modules folder, still the problem persists. Any help would be gratefully apprteciated. Regards Stuart

OK

I am afraid that in all the years I have used this particular aircraft I have not had this particular problem. But then again its the only one I fly in FSX. That is not to say that on occassions I have had problems (usually nothing to do with PMDG as such) and the only solution to a particular issue has sometimes been a complete un-install and re-install. If you can get through to the support (I know more frustration for you in this instance) I have always found them to be human and nice, helpful people. Now, one of the problems I did have was with FS2 Crew and for whatever reason the install of the FS2 Crew had not gone right. I could not get any panels to work and unfortunately the only solution was a complete re-install of both PMDG and FS2 Crew. Regards Stuart

Thanks for taking the time to provide the answers, much appreciated. It would appear I have sort of being doing the planning right but not quite the execution. From now onwards I will make sure the first cruize level programmed is equal to the opt shown on the init page and then program remainder step climbs at 2K intervals until planned altitude. Once again many thanks. Regards Stuart

Does anyone know if there Is a "relationship" between programmed step climbs and the opt/max flight levels presented by the FMC? The reason I ask is as follows: I program a number of cruize levels at "init" phase and hold at each flight level by using altitude, as I think is described in the manual. However, I notice that (according to the flight plan) the FMC keeps on wanting to push the flight level higher than the flight level shown as OPT in the performance page of the FMS. Any input would be gratefully appreciated, even if it is to point out to me I have being doing it wrong all these years. Regards Stuart

Perhaps I am doing something wrong but I use ASE. I follow the suggestions HIFI offer for setting it up plus the adjustments available from having a registered version of FSUIPC. I still get "turbulance" but have not so far experienced the issues mentioned here, despite many years of using the MD11. Regards Stuart

You may find better answers by posting elsewhere but I am pretty sure you will find that the FMC always looks back into the database information held within the PMDG main folder. I discovered this when I "dabled" a bit with making up some approach fixes for an airport once. You may find that in order to add airports you need to manually "add" salient information to relevant data files held in the Navdata folder. Like I say, I believe this will need to be done manually first and you run the risk of it being "overwritten" the next time the database is updated, i.e. an Airac Cycle. I should imagine that to do this would be "risky" as bad data input would possibly corrupt matters. Like I say, you may find better answers elsewhere. Regards Stuart

I was not really understanding what was behind the comments made above about TML. However, I did find this explanation here which may be helpful to others like me Regards Stuart

Nope but I am unsure why it would not work unless of course MS has completed shifted all the goal posts again............ Wait a minute this is MS we are talking about, so actually quite a good question. Seriously though MS state that W8 is "backward compatable" - my terminology - for legacy software used on the new system so not sure why using FSX in DX10 mode would not work on a W8x64 system. Regards Stuart

In a word, no. I no longer use default for my AI even though it is an option available to me in "my traffic". However, if you use default planes for AI then you cannot disable them. Regards Stuart

Using ADE to investigate the airports without lights as showing on my "clean install" system, it would appear that some of the original "stock" airports do not always have lights "coded" for a particular runway. Not sure why when the prototypical airport has them. Anyway, making a small change using ADE and then revisiting the Airport "fixes" the issue. Just thought I would mention this as it supports Paul's findings and airport design. As regards payware, I thought I read somewhere that making 3d objects "work" as runway lights is an issue for some reason. See if I can find the post. Regards Stuart

I would recommend taking the plunge Dr V, I did (despite a few reservations) and have no regrets. Regardless of what others may say on other forums about DX10, the few simple steps and fixes posted here (and elsewhere) I think improve the visual and enjoyment factor many fold. Asfor the lights issue, I still have the default scenery in my fsx installation and note (like others) that the approach lights, strobe effects and VASI lights at some airports do not work and yet at others work just fine. And it is not as if all the lights I mention do not work, seems some do some don't. Does the AddonConverterX software fix this? Or is it more of a design issue in the original scenery file for a particular airport? I for one will not let it detract from my fun, after all that is the whole point is it not. To have fun and enjoy the experience. Regards Stuart

So, for whatever reason the Achilles’ heel of using DX10 still seems to be the lights. I for one appear to have noticeably “lost” strobing, approach and VASI lights at most of the airports I visit. True, sometimes the VASI lights do appear “intermittently”. But (to all intense and purposes) it is as if the gremlin of John Lythgow’s Twighlight Zone nightmare has been teaming up with the folks who worked in the control tower of the first Airplane movie. Has anyone come across a “fix” for this yet, I mean apart from don’t use DX10? Forbidden fruit and all that.......... Regards Stuart

Thanks Paul Kind Regards Stuart

OK just about to jump into the DX10 melee but have a question regarding which version of the "How to" document to use. I visitied this thread a short while back and downloaded the pdf. It shows "rev4 Sept 2012" on the first page. Upon revisiting this thread today, I noticed a new sticky pinned to the top of the forum dated 5th October. Am I correct in assuming that the pdf downloaded from that sticky today is a later more up to date version than the one I have already? Only it does not have any revision information. Many thanks in advance for the clarification and kind regards Stuart

Many thanks Jim, much appreciated. I understand how I can get the icon on my desktop, just wanted to make sure the different installation between the two PCs was not going to cause me issues or problems later on. I did wonder if I had missed the options, so I unistalled and re-installed making sure the desktop options box was ticked. But to no avail. Same result. Not to worry but again many thanks for taking the time to respond. KInd Regards Stuart

Hi Not sure what your installation is but this come sometimes happen with conflicting scenery files. I am no expert but I have had this happen to me and caused the issue you report. There is a bit of software called something like "fsx airport scanner (FAS)" that helps in detecting these conflicts. As always, have a read on the good old www and I am sure you will find out about this issue and what to do about it. Kind Regards Stuart

Hey to one and all A long term user of FSX but I am looking to establish a wide view installation across two PCs. However, before I have even got that far I have come across something really curious. As mentioned I now have two PC's, both of which have recently had (clean) installations of windows 7 (Home Premium) No other software has been installed at present, execpt that of things like adobe reader. To all intense and purposes both installations are a mirror of one another at this time Following well established processes, I have just installed FSX (Deluxe/Accel) on both machines in exactly the same way. Entered the keys as required and activated. Made sure that relevent boxes were checked. It would seem that both installations are identical (checked with vice versa pro) AND YET............ ... On one PC the desktop "shortcut" program icon has been installed AND on the other it has not. .... On the PC without the desktop "shortcut" program icon, one has been installed in the "games" folder. .... On the PC with a desktop "shortcut" program icon, "shortcut" icons (for the read me file, program icon and fsinsider web page) have also been installed within a microsoft fsx sub-folder within the "microsoft games" folder but nothing in the "games" folder. My question is whether any of this makes any difference? Can I ignore this, or am I just storing up trouble for later if I do not find out the reason why, i.e. what else is different? Kind Regards Stuart

Many thanks to one and all for the helpful hints. All helped narrow things down but I did not need a re-install. I have to thank Paul of PMDG support for helping me get to the bottom of all this and its a new one for me. Basically, I took a look at the sound settings across windows 7, FSX and the sound card software itself. Once I had aligned all three and made one element the default, things started working again sound wise in the cockpit. Quite how this happened I have no idea as I have had the sound card for two+ years and NOT made any other changes to system, settings or software since it was installed or bwteen the two flights. However, it does go to show that just because I use one airplane add-on (PMDG MD11) on a dedicated FSX computer it does not necessarily mean that when things go wayward in the cockpit of the PMDG MD11 then its necessarily the add-on to blame. Thanks again to one and all and in particular Paul of PMDG support for his patience and help in getting this sorted. Regards Stuart

Also done the support Ticket, thanks for the prompt. Kind Regards Stuart

Nope because everything else is working just fine and to be honest I was trying to avoid such a heavy handed approach. But if that is the only option I will give it a go. Many thanks for the input, kind regards Stuart

Hey Fellow Simmers I have been exclusively flying this excellent product for years, it has given me hours of pleasure and kept my brain active way beyond its sell by date. For the first time ever, however, I seem to have a problem. I seem to have misplaced all cockpit sounds, regardless of 2D, external or VC view. All was fine one minute but on starting a new flight after an overnight rest stop (LOL) I noticed that undertaking the normal “check list” did not generate any normal clicks or warning sounds, bells, buzzers or anything. Cargo Fire Manual Test = nothing All variants are affected. I can hear the engines running, as well as rain hitting the windows, other aircraft and vehicles passing external to the cockpit. Double checked the manual and a quick search of the forum has not generated anything useful Any helpful ideas gratefully received. Many thanks in advance. Stuart

Last post from me on this subject - txt file updated as attached, corrected some errors in the LUA pointed out to me by others.........Same comments as previous apply.RegardsStuart
