  1. I really appreciate your efforts, Michael. I do have XMLtools properly installed in my main dll.xml folder. Also I regularly fly Capt Sim 727 and the VS command works perfectly with my FSXSP2 installation. I have no keys mapped to autopilot functions. I have been strictly using mouse to manipulate the VS on the autopilot panel for the DC-8 as I do for the Capt Sim. Using pitch damp mode with manual trim would definitely be a novel approach worth trying. Note that DCON (cf the 4th post on this issue) has the same setup as I and also reported the same issues with FSXSP2. Crai
  2. Hi Michael! Thanks for your diligence in responding. I am sure FSX SP2 and FSX acceleration operate the same way. It is just two different paths to the same outcome. My use of the mouse as my controller should also not be an issue because the problem I am having with both versions of DC8 (other than the inexplicable occasional shaking/vibrating) is solely with the VS function on the AutoPilot. The rest works OK. I have an early version of B727 and it has very similar autopilot. When active the autopilot should auto-trim and it must be doing so in level flight (VS=0) since it adj
  3. Testing routine (FSX SP2): 1. First test was reverting to V2.0 and adding in the 2D panel fix. With ASN active, parking brakes were unable to hold aircraft long enough to initialize INS. Thinking the new 2D panel might have some bearing, I removed it from the panel config, and then reloaded aircraft. It still failed to hold position. Turned off ASN, set winds to 0. Still plane kept creeping forward at the gate. 2. Next (still using v2.0 and without the 2D autopilot) I loaded the tutorial flight and after configuring correctly according to the expanded checklist
  4. I never tried v2.0. I immediately upgraded to v2.1. Just so I was on the same page as Michael, I loaded the tutorial with ASN off and did it step by step to make sure I wasn't missing something. The shaking started on the takeoff roll, but I thought maybe that was purposely programmed to add realism. It handflew easily on takeoff but after I intercepted the radial to MKK and activated the autopilot, the problems began. Occasional shaking but the big issue was that it would not hold the climb. I had to manually keep trimming up and down to keep from alternately overspeeding or stalling.
  5. I uninstalled and then reinstalled v2.0 then upgraded to v2.1. No vibrating scenery at the gate this time. But several serious issues during the takeoff and climb. 1. Handflew the aircraft to 8000 agl and then activated AutoPilot maintaining correct climb EPR (per charts based on altitude/RAT) and pitched using VS to maintain 250KIAS. Shaking (or vibrating) panel began immediately. But outside view showed stable climb. Then the aircraft began pitching down and I tried to raise the VSI using the AP but it had no effect. Finally was able to regain stable flight by aggressively
  6. Need format and performa for DC-8 in PFPX. Is this available somewhere or must I create it myself? If so how would I create it? There doesn't seem to be that option in database. Craig
  7. I have uninstalled and reinstalled to see if it was some anomaly caused during my initial installation. I have FSUIPC loaded but don't use it for anything other than VAS monitoring when using PMDG in ORBTZ scenery areas. I will disconnect ASN during my next test flight if I still notice shaking. Thanks for your input. Again, for reference, I am using FSX SP2 (boxed version). Craig
  8. I am still not sure what was causing the shaking (yes scenery and plane with engines off!) when I first spawned the aircraft but I haven't noticed it on the last few flights. But, it still shakes during climbout if on autopilot (OK if I hand-fly). Once I level off with VSI=0 it holds altitude perfectly and all shakiness is gone. But as soon as I start descent (with autopilot) not only does the shakiness present itself again but the plane will suddenly reverse and start to climb. Any attempt to re-establish the descent even with VSI fails. The only solution is to disconnect autopilot and b
  9. I reinstalled DC8 v2.0 and noticed no shaking at the departure gate and began flight without incidence but missed the autopilot popup so upgraded to v2.1. Vibrating scenery came back but this time the aircraft stayed in position so I was able to align INS. After a few minutes the shaking vibrations ceased but reappeared briefly on climbout then disappeared for the duration of the flight. I have no clue what is causing it. I did have ASN weather active but winds were very light. Off the topic: also noticed that the automatic INS loader does not activate after I have loaded a fl
  10. I have FSX SP2 and downloaded v2.1. Also noticed problem with v2.0. Only happens with this product. When I load the aircraft in cold/dark at a parking spot, the whole scenery vibrates very slightly and the aircraft very slowly creeps forward. Parking brake is set and I even actuated Aux Hydraulics but no joy. The movement causes my INS not to align and I get error code. Also interferes with GSX as the plane moves away from the stairs and service trucks. I have I7 7700 and my frame rates are usually 80-100 but I lock at 35 fps to avoid any loading stutters. I have tried placing the airc
