hello i am new to this forum. I have tried to do ILS landings but whenever i press the APR button to align the plane with the runway, it goes berserk. It tries to stay on course but always oversteers when trying to correct its glideslope. And by the time the airplane is on the ground, it is like 50ft. away from the runway and off track. this problem only occurs with big jets (md-11F in this case) . i tried the same procedure on a learjet and crj-200 and it worked flawlessly. any help would be appreciated.
some downloads' autopilots are not as good as others.
I find the best bet is to use the autopilots hdg setting to get you lined up with the localiser then once you are on the localiser wait until you are just about to intercept the glideslope from below and then hit the approach setting. this way the appr doesn't have to chase the localiser or the glideslope too far and therefore shouldn't overcompensate too much.
also make sure that your speed is correct, if your going too fast it seems to find it harder to track the lines.

Very well stated Spuddi. I agree that it takes a bit of good timing to switch from GPS to NAV and click the APP/APPR button just as you intercept the glideslope. I've found that the technique of using the HDG in A/P to be much more consistent as well.
I remember some textures I downloaded with a few extra bits and bobs. I couldn't get the autopilot to follow my route. It was zig-zagging all the way along the route. I deleted those files straight away!!
Here's a guide about how to use the ILS. I hope it helps.
First of all, let me introduce you to the superb, easy-to-read and understand guide of the skillful Fire_Emblem_Master:
THIS IS FOR IFR FLIGHT!
1. When ATC says something liek "WifeBeater 767, you are 32 Miles away. Turn right heading 105, descend and mantain 2,500 feet, cleared ILS runway 36R Approach". You have to click on your MAP icon in your cockipt. Then, move your mouse over the destination airport. Mind you, the airport MUST have the ILS feathers (thes are the green things that point to the runway). Double click on the airport. A list will show up. Scroll down the list untill you see a chart that shows Runway numbers. FInd 36R, or whatever your runway is. You look to the right and see a radio frequency. We'll use 100.100 because its easy to remember. Don't forget the frequency.
2. Open up your Radio Stack, and enter in 100.100 in the NAV1 Radio, usually the righmost radio number is the one that can be messed with. After you enter it 100.100, using the mouse wheel or clickin it. Press the button that looks like thsi somewhat, its in the middle of the 2 radio displays <-----> That changes the NAV1 Radio frequency from whatever it was, to what it is now (100.100)
3.Turn on the NAV1 Radio by clicking the switch at the bottom of the radio stack, unless its already on, like with the LearJet.
4. If you have Autopilot, and you are using GPS to follow waypoints, switch the NAV/GPS button back to NAV!!!! YOU CANT FORGET TO DO THAT!!! YOU'LL BURN AND DIE IF YOU DONT!!
5. Follow ATC directions to approach. Now, when you approach the Runway, you will see the pink arrows near your attitude indicator move...usually Heading first, then Altitude. Simply fly in the directon and atitude of the pink arrows intull they center themselves, that means you're on the glideslope!
6. If you wanna use the autopilot to fly the approach, simply follow steps 1-4, then click the APPR button on the autopilot panel.

I'm just kidding. Anyway, Fire_Emblem_Master should get an award for this guide. It helps a lot.
Well, this is your first step. There are different approaches that you can make to a runway: ILS, VOR, NDB ADF, GPS, and visual approach. I'm going to talk about the ILS approach, since Fire_Emblem_Master's guide refers to it.
When you are approaching the airport and before you contact with the Tower, you can do two different things:
1. Use the App. mode in the autopilot, so the autopilot makes the approach for you and you don't have to move a finger. Well, actually you do have to move your fingers. You need to control the speed and flaps, landing gears, autobrakes, etc. But the approach is perfomed entirely by the autopilot. To land, just disengage the App. mode, switch off the Auto Throttle and other switches if you want, and land the plane manually. That's what I usually do. But is good practice to perform a hand-approach. But I also perform hand-approaches, which I'd recommend you to learn it. This point comes to the second option.
Note: To use the App. mode you should have to se the NAV/GPS switch to NAV and you also should have the ICAO code of the airport in your GPS.
2. Don't use the App. Mode and do the approach manually. I know this is hard but you just need to practice, practice, and practice.
Before approaching the airport, you should tune to the ILS frequency of the runway. That means, set the ICAO code of your destination airport, go to the frequencies page and find your ILS (or whatever approach you use) frequency. You should set the right frequency. Example: you are going to land on runway 09, look to the ILS 09 frequency.
After that, set that frequency into the radio stack and turn on the Nav 1 or 2. Also check the MRK (marker) button, which is going to make sounds when you pass through different markers, like OM, IM, and MM. Then, arm the spoilers, set the flaps, retract the landing gear and set the autobrakes.
After this, all you have to do is look at Fire_Emblem_Master's ILS guide. That would help you. Start turning towards the runway heading and try to have the glide slope and the localizer needles in the center. If you have both needles in the center you are right on the altitude and heading. Just keep this and land manually.
That's it. Was it easy? Complicated? Boring? Did you get tired reading all this? I know, it's long, but helpful.

just printed f.e.m's info as a reminder, sooooo good.
f.e.m, we bow to your knowledge!!!

I know you do... 😂 😂 😂
Kiddin!
His guide is so cool. I used it once...now I have it memorized. And that's exactly what I do when I have to land in ILS.
