Title: Some measurements questions about the overhead panel
Post by: Ivo de Colfmaker on Fri, 9 Dec 2016 19:50
Hi,
I started to build my home cockpit , don't have a big room, so have to make some consessions regarding measurements.
What I would like to know is , is the angle of the overhead panel about 16° relative to the floor?

And the front of this overhead panel , where the landinglights are is this +/- straight above the full cutoff switches?
And finaly, what is the width of the centerpost?
Thanks
Ivo

Ivo, perhaps it would be best to draw a diagram to show the dimensions you mean (to prevent confusion).

I gave some dimensions to someone a long time ago and he created some drawings. Unfortunately, I can't remember who did the drawing to give him credit.

(EDIT: One of the original drawings)
Original Drawing 1 (http://www.members.iinet.net.au/~b744er@ozemail.com.au/PSX/RelPos.JPG)

I have one diagram which shows the overhead panel at about 18 degrees (relative to the floor).

Note: I can't remember if I checked the floor angle. The aircraft may have been tilted.
