    Hi there,

    starting my new project : simulator for planes on DCS (not helicopters) and I have a very simple question : is heave useful for flight simulation ?

    I really see where heave is used for car simulation : bumpers, holes and road but I'm wondering for flight sim ? maybe for turbulences or just for the landing when you hit the ground ?

    It will help me to decide 2 or 3 DOF project !

    Thanks a lot

    Hi @dureiken,

    yes, heave is definitely useful for flight simulations. But in contrast to racing simulations where you want to feel bumps etc, in flight simulations you rather want to feel the long-lasting heave force that is applied to your body while the plane is gaining or loosing height.
    Example: During takeoff, you feel increased G forces on your butt for quite some time, and when the plane falls into an air hole you feel lighter than usual, which can also last longer than a road bump.

    However, for me this is no reason to change from my 2DOF to a >2DOF rig. Instead I prefer G-Seat paddles on the seat bottom, because they provide the long-lasting heave force as long as I need it.

    Thanks for your answer. Would yaw be more interesting for flight sim ?

    My final project would be to have a gseat over a 2 or 3dof motion platform, is that possible ?

    Yaw : unless you can build a 360 yaw capable sim - no. Building a G-seat - yes - a few of us have them.

    Do you think thats a gseat with VR is more immersive that motion platform ?

    Thanks

    I think both are complimentary but the likes of @SeatTime, who uses both, are in the best position to advise.

    Yes !...... i am a pilot irl (+10khres) i use a real (but static) simulator for training. In a big commercial airplane there are not a lot of gforce and for that raison a static one can do the job but... it is difficult to keep the plane stable because we have no feeling at all . Personnaly , i prefer a gseat to feel the plane. A motion platform can do the job but it is more limited and you have to take in consideration that a platform with a poor calibration is more distrating than useful.
