    Re: RAF Fighter Horizontal convergence

    Hi,

    I took some time to correct a few things on the Spitfire calculator (details) and created one for the Hurricane. Hope you'll like them ;)

    Hurricane H&V convergence calculator : https://goo.gl/ZyClQr
    Spitfire H&V convergence calculator : https://goo.gl/g9QRNt

    As before, please let me know if you have any question, remark or if you found a bug.

    Cheers,

    DeX

    Edit : I had forgotten to allow DL permission, it should work now. Thanks David for the heads up

    Thanks for this, Dex!

    I'm currently evaluating your data under combat conditions. It may take awhile to find a 109 that will just hold still long enough for me to steady my sights on him!

    I've got three words for you:

    Single Player Mode

    just set up a RAF 109 and shoot him to bits!

    Re: RAF Fighter Horizontal convergence

    I must admit I'm a little overwhelmed by the math here, but I want to try your suggested convergences. I do have a question; Why do the vertical convergences between guns 1&8, 2&7,3&6 and 4&5 not match each other the same way the Horizontal ones do? I like to load tracers only in my outboard guns, and this might mean that they will not converge on the same point?

    Hi Murph,

    This is just a personnal preference. Having them like that increases the "spread/showering" (see lateral view of the calculator).

    Yet, we are talking about 15 vs 30cm between points of impact here. So you can, and should modify those values to suit your preferences.

    As a reminder for everybody : yellow cells on the calculator tab can be modified and charts will automatically update to display trajectories/guns on target.

    Regarding tracers : for info, those rounds contain pyrophoric materials which tends to make them lighter, which in turn makes them less energetic (+ they won't retain velocity as well as standard rounds). Also, as per TF posts, an incendiary/tracer will be less efficient at starting fire than a "100%" incendiary for example (due to the reduced payload).

    Cheers,

    DeX

    "Suit your preference" is the operative advice here...

    I choose the outboard guns for tracer ammo simply because I like to strafe columns of vehicles. The tracer divergence in this configuration will show the lateral limits of your impact points left and right of the column. All of the bullets are "between the white lines" so I don't continue firing when too far from the target.

    It serves the same purpose in air to air combat, and really helps from the 6 O'clock firing position. Tracer only helps me as a pointer during deflection shots... not enough time for me to get analytical... so I guess inboard tracer with lower convergence/divergence angles would be best for that.

    It kinda makes the argument for multi-barrel guns! High rate of fire with no convergence at all!
