Majestic Software & Lockheed Martin's Prepard3D v5

edited May 2020 in ANNOUNCEMENTS!!

Fellow Simpilots,

Lockheed Martin has released the long anticipated version 5 of Prepar3D. For many it was a surprise, but most knew that there was something lurking in the pipelines for some time.

So what about the Q400's compatibility?

Well as many of you have already discovered, out of the box the Q400 seems to work and yes does appear to be fairly stable operationally. While we are happy for that, we working on some issues on the back-end of the add-on, which to the naked eye or average user may not be an issue during use. The installer as most have realized simply requires changing the path to the new simulator. We have held off making an official announcement primarily due to the fact that we wanted to see what we were up against based on the official P3D v5 release (as we always do). Looking around at some of the Twitch/YouTube streams, forums and social media groups what we see and hear is pretty much what was expected, however, what may work for one may not necessarily work for the other, so do not be disappointed if your Q400 does not work as expected.

When can we expect a new installer for Prepar3D v5?

New installers will be compiled after we are able to fix the few issues that we have identified and considered a priority. For this we have decided to await LM's first update/HF or an update that allows proper functioning of the aircraft. As several users have reported issues with their graphic cards as well which have been able to replicate.

Some of the items to be addressed are:

  • External Visual artifacts

  • Sound adjustments based on the use on the new DX12

  • CPAN functionality for specific items related to aircraft, most items can still be changed via the mjc84.ini (be sure to make a backup of the original before making any changes to your .ini file or any file for that matter)

We will not be supporting any issues reported on the forum regarding Prepar3D v5 until we officially release the new installers for the PILOT and PRO Editions.

We thank you for your continued support, and please do your best to be safe amidst of the COVID Pandemic.

    Today I made a terrible mistake in V5, I change the from Direct to RAW input control and now when I choose the q400 I get CTD.
    No way to solve this even getting back on Direct mode.

  • seems great ..

    alert at startup: this gauge version must be used under Prepar3D v4.0 or higher

    error=Failed to load visual effect "mjc84_dome"

    Just reporting this as I know we're not at v5 just yet. Not sure if this falls under "sound adjustments" but I've noticed that to make the sounds appear to come from the correct position after panning the camera, I need to click somewhere within the P3D window and the sound positions are updated. I'm using Chaseplane + P3Dv5 HF2

    I made a video in case you needed to see:

    Each time I stop panning I perform a single click and the sounds are corrected. Got to love and API change :joy:

  • Hi Guy's,

    Two weekes ago i installed the Q400 Pilot edition to P3Dv5.
    I just pointed the installer to P3Dv5.

    Beside the fact that the sounds are a bit different i have problems with the fysics.

    Today i removed it from P3Dv5 and i will wait for the original V5 installer.

    I feel the ground and flight fysics has to be tweaked.

    On the ground when i steer right or left the a/c speed is increasing (or decreasing) rapidly (when i steer with the tiller, wich i pointed to be controlled by my yoke), as if i set Time acceleration to 2 and back to 0,5.

    When i am on approach i hardly can keep the ILS because the aircraft is so sluggish along the longitudinal axis and yes....Yaw Damper is on.

    For the record (before people are going to say the i should learn to fly the Q400), i am a licensed twin engine RW pilot and FS pilot for 28 years and have used the Q400 in P3dV4.5 a lot.

    I hope the aircraft will be improved when the P3Dv5 version comes out, because it is a great product in V4.5


  • While we are not officially supporting the platform as of yet the majority of our users have no issues with the aircraft.

    It would be appreciated if you informed readers of this post about the specs of your machine including the operating system and what changes you may or may have not attempted within the CPAN to possibly address the issues you are experiencing.

    I suspect/ASSUME you are running the windows 2004 update.

    If so there are threads on this forum regarding this.
