Jan I'm assuming I download a fresh copy of the 737-300 right? Or do I not need to do that.

Yes Bulva. I'm installing to a different directory structure - then I'll copy my preference file to the new install.

Thanks - and I see that the installer lets you pick a different location so that can work too.

So do you rename the existing XP root directory and then download the clean version?

Yep - sounds about right....thanks. It's a little puzzling that the sim works fine with other aircraft.

It's late here - so signing off. I'll check in tomorrow morning PST US. Thanks for working with me on this. Looks like I may be headed towards a clean re-install of the AC.

Ok - got it. I'm pretty sure it's done that no matter what the order, and it didn't matter with other AC. But I'm trying it again. It does the same thing no matter what the order.

Isn't that what you told me to do? I thought I was following your instructions. And I've tested this with other aircraft and they don't do that.

OMG - such erratic behavior with moving the AC with the map. I was able to position it as you suggested, but as soon as I unpaused the aircraft started shaking and pitched straight up and rolled. The video I'm sending you is what is happening now. I've rebooted, restarted XP multiple times, reloaded the aircraft, did repair failures - anything I could think of. Probably tried this 15 times, with differing results. The AC looks normal when circling around and inspecting. Also sometimes the generators are not on when it spawns, sometimes they are. Sometimes the IAS changes. Most things stay the same, which means the aircraft is partially remembering the state from previous flights. Is there a way I can make it 'forget'? It seems like something is really messed up. 1233866641_X-Plane2021_11.17-00_07_42_01.mp4

I will try this - and many times I've come into the glideslope at level flight 4000 ft and just pass through to the other side without capturing the glideslope. But perhaps there was something else going on....

Ok - thanks I'll try that. I didn't know you could do that - cool! I'm been having the sense that it's something about the initial state when it's spawned. And slight variations cause major issues. Also the sim persists many but not all status, sometimes changes some of the status when spawning etc etc. So how it arrives in the air is unpredictable. Probably something about differences in the final state persisting in some weird way into the next spawn - unpredictably!

That's great Jan - I'll start working on these ideas. I figured that since I wasn't seeing it plastered all over the Internet it was something quirky about my config. And I'm determined to figure it out. Thanks - I'll get a video uploaded tomorrow.

Thanks Jan - I've been having fun! I've spent two years gradually moving up the complexity level starting with single prop, twin props, twin engine very small jets, then larger twin engine jets, and this is my first airliner. I am engaging all of these at study level and doing a lot of practicing just in case the pilot on one of the many flights I take each year needs help! Anyway it's been a learning curve, but I'm glad have a firm foundation in the basics. In addition to the PDF Tutorials I also have the Mike Ray book and have watched a number of tutorials online, including yours! Ok enough of that.... I understand what you are saying, on the Honeycomb Bravo Throttle quadrant the trim wheel is perilously close to the gear lever, so it does get bumped in tight quarters. However most of the time I have this issue it's not in CWS P or CWS R mode - it's CMD on the captain's side and on both sides a bit later on in the sequence. So now the sim seems to have lost the ability to manage altitude with AP. With CMD on annunciator, the altitude set at 3800, ALT HLD button lit and ALT HOLD annunciator solid green, it does not control the elevation. It simply drifts downward at an every increasing angle. I am getting the main console A/P red flashing warning light, however, and do not understand why. Just a minute ago with the same scenario it ascended into a stall and then started yo yoing. What the heck? Don't know whether this is related or not, but on occasion some of the buttons like for the EHIS control panel do not work, and ALT HDG and other MCP buttons do nothing no matter what state the AC is in.

I've looked elsewhere for this topic and have not found anything recent or exactly pertinent to my issue. I'm running X-Plane 11.55 in Experimental Flight Model, Downwind ILS not disabled. I have 2 years of X-Plane - I'm retired - it's COVID - so I likely have over 1000 hours in on X-Plane. So not a newbie. I have not had this AC previously and so had a clean install of the latest version about 3 weeks ago. I'm running through the IXEG tutorials that are dated 2016, so not sure if there's something wrong with those. (KLAS ILS info has changed but I've taken care of that). Anyway I've run Tutorial 1 a number of times and am now comfortable with the basics of flying this aircraft. I've been in Tutorial 2; Autopilot and Flight Director for a week now - probably over 50 hours trying to get the ILS Dual Channel Autoland sequence to work. I've been successful 6 times with likely over 60 attempts and cannot duplicate those particular runs. The issue is that even though I approach the G/S from below, am right on with the heading and inline with the ILS for runway 26L at McCarren Las Vegas the VOR/LOC and G/S armed, they are not captured (with a few exceptions) and I wind up heading for the dirt quite a distance from the runway. As far as I can tell I have the AC configured and positioned as the Tutorial describes. In an effort to cut down on the amount of time required to keep trying this I am now using the X-Plane function to place the AC 10nm out from 26L. I've attached the pics for the initial configuration and position when I'm spawned 10nm out. Then I have a pic of the result of that as the approach progresses and attached the log which I'm pretty sure will be useless. I also pasted the procedure I'm using below. I suspect it's some very subtle timing and/or positional issue. Additional info: Coming back to this after a few hours I was able to get it working 4 times in a row, then after that - changing nothing - very weird behaviors primarily with altitude. Basically not holding the altitude specified, or not acquiring the altitude specified. Gradual ascents or descents or yo yoing - everything is setup exactly as before when it worked several times. Also when the plane spawns the aircraft config can be very different; A/T off, FDs off, N1 on instead of SPEED, ALT HDG, APP and ALT HOLD buttons not operational. Very unpredictable and unreliable. Anyway if anyone has an explanation for this - I would love to hear it! 737-300 ILS Dual Channel Autoland Procedure Set plane 10nm out from RNWY 26L McCarren KLAS Put flaps and throttle in approximate position needed after spawn. Spawn, let equilibrate for 5 seconds or more so to acquire altitude, speed etc. Then hit pause and check configuration and set as necessary. Use the EHSI Map setting – 20 nm, EXP VOR/ILS VOR/ADF Tune Nav 1 and Nav 2 radio to the ILS frequency for the runway 111.50 Set the CRS 1 and 2 and Heading to match the runway heading and make sure it’s in MCP HDG SEL. (259) Set MCP SPD at 140 kts flaps 25 Set MCP ALT to 3800 ft. and MCP ALT HLD AP CMD A on APP Mode on FD’s on, A/T armed, SPEED mode on Unpause. Press CMD B for the AP. This will set up the dual channel autoland. The AP should now keep the plane on the ILS heading and will eventually intercept and then fly the glideslope. Make sure it’s not coming in above the glideslope as that does not work. When the glideslope is captured the green G/S annunciator will appear. When on final speed will be at Vref +5, (127) flaps 40 for low visibility. When the glideslope is captured the MCP HDG, APP indicators go dark and only the Speed MCP is active, along with the CMD A and B indicators of course. Airplane lands.
