• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Heywood Air Starter Is this possible?

Beginning development of The Kreutzer Air Coach trimotor which uses a Heywood Air Starter to start the three engines. Essentially the pilot selects the engine to start, with an engine selector switch then presses a button that injects compressed air into the cylinder, starting the engine. The selector is then moved to the next engine in sequence and again the button pushed. Is it possible to code this in P3D so that a single button starts the engine that corresponds to the position of the selector switch? Example below. TIA for any input.

Yes. You will need to apply a fuel tank, open the fuel valve and run the starter one after another. It can be done as I did something very similar a long time ago. If that produces a start that is too sudden, you'll need to delay the opening of the fuel valve and allow the engine to motor. BE AWARE: there is a bug (feature?) in all versions of the sim that only allows for four (4) seconds of motoring before the starter shuts down. If you need the engine to motor for longer than that, you will need to detach the L:var that turns the prop from the RPM variable. Motor the prop using the L:var and feed in the RPM to that L:var when combusion is confirmed.
