^ Any suggestions?

turn the volume of the ms atc, to zero. ms atc may have more things to say, lots of ear candy. but rc will talk to the ai, if they warrant it, and you are on the same frequency as they are. jd

The optimized settings for RC are Display Text off, PreRecorded Chatter off, AI Chatter ON, Interact With AI ON. Prerecorded chatter is more ambient in nature and not related to AI present and basically consumes processing not needed. AI Chatter and Interact with AI provide chatter with AI in your area and on the same frequency and also some RC protection resolving conflicts with your aircraft and AI in certain situations. Display Text produces ATC commands visually but really impedes performance.

Thank you very much JD and Ron! EDIT EDIT: Now the only problem i'm having is that after when I file the flight plan, I am not given an assigned altitude but after take-off he says to watch my alt and that my alt is... and doesn't say anything else. Soon after my FO just says "roger." It seems like it's skipping here and there?

Check the cruising altitude on the controller page after you enter the plan. RC enters the altitude divided by 100 (it adds the two zeros on the display. See what it reads. It is derived normally from your flight plan but you can change it there. Do this before you START RC. I always use the controller page to proof the items listed. Try keeping the comms and requesting a repeat to see if this error is consistent. If you accelerate FS by more than 2X problems can result especially if add-ons consume a lot of processor time. If you have random skipping you also could be facing a low RAM situation as RC does a lot of audio buffering in RAM. If using FSX and a heavy resource load from graphics and heavy code processing this also can cause intermittent issues if your pc is not powerful enough. DFor best error freee performance run only at 1X.

Thank you Ron! I figured it out before you posted hehe. Now... the last and final thing is, why do I not get taxi instructions after landing or before take-off to the runway?

RC4 does not give progressive taxi instructions. Here are some ideas: There is one payware program that can do that as an add-on. It gives you an overhead view and draws a taxi path on it. http://dbsim.com/ has that Airport GPS product for either FSX and FS9. I'm not sure if there was a comment about it if it can build its database correctly from installed add-on scenery. Along with IFR charts I also get airport diagrams. Several sources exist. I then use those charts to determine a taxi path. I have also used AFCAD for FS9 and can use use ADE9X freeware to print airport charts. You can also use an overhead view in FS to taxi. That has the advantage of showing ai in your path so you can detour if possible. RC will speak a gate number you assign on the controller page but other than that does nothing in parking functions. There is a function in FSUIPC called the traffic zapper. You can assign a hot-key to it and it will 'nuke' ai within a certain coverage are of where your aircraft nose is pointed. See the users guide for FSUIPC. I'm not sure if RC registers this function for you. Not realistic but it will clear a gate for you. An advanced method is to edit the afd layer of airports you will be using. Pick a parking space and assign a very small radius which will block ai from parking in it but will still show the gate scenery. ADE9X will do this safely on many airport scenery projects. AFCAD is for FS9 only and while simpler to use is not really safe for editing all FS9 scenery. I then mark on printed airport charts my 'reserved' parking space. Some add-on scenery uses static aircraft for decor and those can usually be removed from the scenery. You can then use the same parking area. Usually in the scenery folder their is a file called something with static aircraft in it. Just rename that .bgl to .bgh. Scenery documentation usually describes that function.

Oh, I see. So how is it the Microsoft was able to encode this in their software?

Static aircraft are just like buildings. They are 3d models positioned within the scenery. MS does not have any static aircraft to my knowledge in any of their scenery. The default scenery, like add-on scenery, contains nodes for all of the elements such as taxiways and runways. Some are special and classified as hold short positions. In addition there are special locations called start locations, invisible, that define where ai aircraft should touch down and also go into the take-off position. These requirements are true of add-on airport scenery as well. If you are referring to the progressive taxi function, the code works like some courier programs where the end point and start point (parking and runway ends or your current aircraft position) are measured or defined. There are different methods but it is a brute force trace of paths to find the shortest most direct route subject I would hope to minimum active runway crossings. These add-ons I mentioned use a similar methodology (called an algorithm) to trace possible paths to get a resulting route. It is a fairly high mathematical discipline beyond me and the usually many paths make getting a result very complex. Below is an example of a special folder in an add-on airport scenery install where you can add these static items to the airport scenery folder as an option: If they are already in a scenery folder you can rename the .bgl to .bgh to avoid having them show up. Some authors in this case provide a separate install option to avoid them to reduce loading the rendering of static objects where users have performance problems or they might interfere with the user's desired procedures.

Thanks for the explanation but you misunderstood what I was asking. My question was refering to the first sentence of your 2nd to last reply. In any case, what I was asking was how Microsoft made flight sim ATC able to give taxi instructions and tell aircraft to stop and go etc and RC can not.

RC is expected to provide progressive taxi instructions in a new version when ready. RC does not control ai. It does only to try prevent ai encroaching on the runway when you are switched to tower, try to slow down ai in back of you to provide separation when you are on final, and issue diversion instructions to you and divert ai when enroute in some cases. FS has a dedicated ai engine module to control all ai functions. The primary lead development team of FS9 was a group of I think five members. They had access to all of the FS code so they had that advantage plus the number in the team to program. They were in the game development division known as ACES studio, now defunct. RC is developed by one coder, jd. MS only provides limited documentation about the different parts of FS. Fortunately for RC and other application for FS9, FSUIPC provides an interface to many of the functions in FS9 to control some ai functions, read their status regarding navigation and intentions, and drive and read FS weather near the aircraft. That developer, Pete Dowson, used observation of various windows process messaging and FS executing code to interpret what was going on and by observation to develop an interface. He inherited the start of that way back in FS history from a previous developer and then continued it.

Okay, thankyou!
