    I'm trying to figure out why I keep losing power at cruise. I have the auto throttle, and AP on in VNAV and LNAV mode. Everything just goes completely dark. Not like running out of fuel, no engine fire, nothing. I know, i'm not giving much to work with here but any help would be appreciated.

  2. Hey everyone! Ive been playing with P3DV4 for a while and I've decided to get a new addon aircraft to play with. I went to Rikoooo's site and found an Antonov AN-26. I've installed it and it all went well, it even showed up in the vehicle menu (although preview was unavailable). I started a flight anyway and the aircraft was basically completely invisible other than the lights on the wings and tail. Heres a picture: https://imgur.com/qI8X7GU I'd appreciate any help from you guys!

    Hi there, I have the latest version of this amazing aircraft. I am noticing an issue where it is impossible to turn the plane during taxi via nosewheel steering. The tiller works, the rudder pedals show movement and in fact the nosewheel shows full range of deflection but only the tiniest shift in heading results on the ground. It is as though it is skidding and can't get grip on the pavement. However, this occurs at even very low speeds, even using differential thrust and braking has no effect. The nosewheel will point, say 30 degrees to one side or the other and the plane just taxis forward as the nosewheel drags. Have never seen this before. In flight, I have fu…

    Not sure if this is a config error or install issue. But, I turn on WXR and use tilt and CAL, and nothing ever paints on the display during precipitation. I have Active Sky set on WX Radar client in the manager, and AS2016 on a network config. How ever the Terrain radar feature works well. but no WXR. also be advised the Co-Route entry was not working at all. The installer does not come with a Routes folder. I had to Manually create a new folder and label Routes. And now it works. FSXSE W10 Home

    Hi guys, Doest anyone know which settings or values i need to play with (behind the scenes) to make the volumatric fog less bright at night ? In night (and especially full moon nights and low visibility conditions) the volumatric fog shows up very bright and white when it really should be black if no light reflected on it. Must be some shaders to play with here to reduce amount of light the vol fog is getting. Thank you !

    Hi guys, So I recently bought P3D v4 and unfortunately I am having a problem with these so-called 'Micro Stutters'. I am running the sim with a constant FPS of 59 (Limited Using Nvidia Inspector). My monitors refresh rate is 60Hz. I am not using any forms of V-Sync. Here's my problem: When panning the view in the cockpit it is smooth except for the intermittent stutters that are occuring. There is no screen tearing, however these stutters are incredibly annoying. They are not that bad, the game is playable but it is not as smooth as it should be. I just want to be able to pan around the cockpit smoothly without these micro-stutters. There are no oth…

  9. When I use P3Dv4, The tarmac, the top exterior surfaces of my aircraft and the VC of some cockpits are so bright that it is difficult to discern taxi lines, cockpit switches etc, I have been adjusting the Brightness, Saturation and Bloom but cannot get a happy medium. When I thought I found a solution to the above, the result created an outdoor environment in which what should have been cloudless sunny sky, now made the airport look like it was overcast. Can anyone recommend a good setting of Brightness/Bloom/Saturation that I can try? As always, very much appreciated. Rob

    Recently I noticed a glitch with the default airports, where the default airport ground texture would be black when view during cruise, and then replaced by random landclass and night textures when one gets closer. (Default KPSP shown) I checked it wasn't a shaders problem as the glitch persisted after I deleted the shaders folder and prepar3d.cfg. Maybe it's a landclass problem?

    Hi, This may be in the wrong forum and I have posted in Flight1's support forum as well with no help at all. Anyway if this post needs to be moved please do. Anyway I have the GTN750 complete. I updated p3dv4 to 4.2. I also updated my GTN to version 2.05. For the life of me I have tried everything to get this product to work. I am getting incompatible version errors when I try to load a plane that has the GTN installed. Please help. I am desperate. It worked fine before the update etc. Now I can not use my GTN. Thanks in advance. Regards

  14. Does not matter what aircraft, where I try to spawn at, or even if I'm using scenery. Happens with default JFK textures, happens with FSDT's JFKv2, with Traffic sliders set to 0% and 100%, and with autogen turned on or off. No other airport I've loaded into has had problems. Unsure where error logs are, but point me in their direction and I'll provide them. in the mean time, my PC specs are Windows 10 64-bit i7 7700K OC'd (stable) to 4.9GHz 16GB of RAM, DDR4 @ 3200 GTX 1070 6GB P3D is running on an M.2 drive

    Hi I am using the King Air B200 Version 2 for use in my P3D Version 4.2 and use a Saitek X52 Pro joystick and throttle combination. All the buttons have been set for various operations eg (Flaps, Landing gear etc) but the POV in the B200 only allows upward movement in virtual cockpit and no downward movement and scanning of the cabin (if you can understand what I am trying to explain). The POV works without a problem in PMDG 747,777, Realair turbo and default aircraft that I tested. I have recalibrated the Saitek X52 Pro but the problem remains only with the King Air B200. Any advice/assistance with this problem would be appreciated Regards Noel Southa…

After trying many settings a many prepar3d.cfg tweaks, I totally uninstalled the simulator and the graphics drivers and reinstallled back again, keeping Prepar3d with no addons and first launch settings. Nothing changes, also if i slide all scenery settings to the right and i check "high terrain textures". I have hyperthreading disabled and default nvidia settings.

    Hi guy's, Today on my approach to ORBX KSAN, in P3Dv4.1 with the Maddog, i armed the speedbrakes at 4.500ft, wich resulted in a CTD. Anyone experienced this before? Later i did a take-off and roundflight (over the exact same point) followed by a landing at KSAN to be sure it was not the ORBX scenery that caused the CTD. I could not replicate the problem.
