737 Yoke/Control Column slope question

[diegov]

Hi Fellow Cockpit Builders,

Im just setting the limits of my control column and am trying to understand the neutral, forward and backward slope in degrees.

From document found on markuspilot.com website: http://www.markuspilot.com/BOEING%20737%20MEASUREMENTS.doc

It states that neutral should be 10 degrees forward of, i assume 90 degrees. ie 80 degrees for neutral. Forward MAX, "elevator down" should be an additonal 10 degrees forward from neutral.. ie 70 degrees. Backwards/AFT MAX, "elevator up" should be 10 degrees back from neutral.. ie 90 degrees. My confusion comes from the diagram illustrating that the Backwards/AFT max is actually greater than 90 degrees.

Would someone be kind enough to clarify the positions for me?

Thank you

Diego

Its more likely + / - 20 degrees.
yes control column does come back past the vertical

angular measurements are difficult. approximate.

Hi Mark,

Thanks for the response :)

I have settled for 5 degrees past the vertical for my full elevator up position..

Cheers

I have read that the neutral point is 8 degrees foward of upright and then the nose down and up are 12.5 degrees away from that. So nose down is 20.5 degrees forward and nose up is 4.5 degrees back.

This from http://www.737ngproject.be/ on the yoke page and I believe that it is correct. I built mine to these dimensions and when sat with my chair at the right height and position it feels comfortable. No stretching and the yoke doesnt need to be into your stomach before you takeoff. I just need to inteface it now!
