    Question Share a Fellow Builders Visual Dilemma

    Most of you already know David Allen and his project. He and I communicate on occasion related to Flight-sim building topics.

    With his permission he is allowing me to post an e-mail sent to me. I think this is a valid topic and not a uncommon dilemma.

    David is asking for mine and anyone Else's thoughts... let's go for it

    Matt O.
    -----------------------

    I have been doing more work trying to understand MSFS Visuals.
    If I block off all of the windows except for the two forward
    windshields then I have the following viewing angles:

    Pilot's angle to the left 34 degrees (View through Left forward Windshield)
    Pilot's angle to the right 72 degrees (View through Right forward Windshield)

    Copilot's angle to the left 34 degrees (View through Right forward Windshield)
    Pilot's angle to the right 72 degrees (View through Left forward Windshield)

    Both the Pilot and Copilot down angle cutoff is 15 degrees (Both
    Forward windshields)

    So I have created an image of the 737's flight deck and the viewing
    angles of the pilot and copilot.




    Now if I take that information and make a 3d model I get the following:



    The Black portion is the Runway
    The White portion is the area of the runway that can NOT be seen from
    the flight deck forward windows. This is the 15 degree lower window
    cutoff angle.

    The Purple lines represent the Pilot's left angle of 34 degrees 0
    degrees Straight ahead and the right 72 degree angle.

    The Green lines represent the C0Pilot's right angle of 34 degrees 0
    degrees Straight ahead and the left 72 degree angle.

    The two Orange lines would be hidden from view when the pilots &
    Copilots eye point are at the proper elevation.



    The above image is looking back at the flight deck from a point in
    space, you can see how the White portion is hiding the area of the
    runway that can NOT be seen from the flight deck forward windows.

    This also shows the lines in 3d



    This image is perpendicular to the to the runway (90 degrees) and at
    the pilots eye point elevation. This also shows that the 34 and 72
    degree purple and green lines are at the same elevation as the pilots
    eye point elevation. The 0 degrees Straight ahead lines (green &
    purple) appear as dots. The two orange lines are hidden behind the
    straight ahead green & purple dots.



    This image is looking forward from the above and the right side of
    the flight deck.

    The final phase will be to get some help from someone who knows how
    to do airport scenery and place the lines in a known locations and
    then experiment with MSFS visuals until all of the lines can be seen as dots.

    Your Thoughts

    thanks for sharing this, visuals for me are still in the "design" phase unfortunately, this information will be in-valuable.

    Hi,
    I'm in the process of setting up an outside display with 3 projectors, projecting on 3 screens that are at an angle of 135 (or so) degrees to each other.

    I will report here on how it works. The setup should be finished in a month.

    Regards,
    Hans
