Hi Guys

  

 About a year ago someone published a photo of a  really neat way to mount a Ray Allen POS-12 positioner for the flaps.   Unfortunately when my Yahoo email account was hijacked, I lost that photo.   A search of the archives only turned up a discussion, no photo.  Anyone  have that photo handy?

  

 Thx,  Rick

I found a pic in the advanced flight systems manual which showed essentially how I did it.

I also used this but be aware the movement us not linear also don't overextend the POS or it will break.

It's a lovely installation so I copied it too.  Just beware that if you squeeze the two rivets holding the sensor to the aluminum plate as much as "normal" you will split the sensor flanges, so go easy.  Using screws and nuts is probably more clever.

I used essentially the same setup. Nice part is that you can position the Adel clamp (by choosing how high on the aft spar the hinge is) so that the first 3 degrees of travel translate into as much sensor motion as possible (e.g., sensor arm is perpendicular to the clamp); near full flaps there is less sensor motion per degree of rotation of the torque tube. I had concerns about seeing the difference between reflex (-3) and trail (0) but with this set up it works just fine.

Bob, I hadn't thought that far ahead, but I understand what you're saying.  Thx for pointing that out.  I will be sure to position the hinge accordingly.

That's a great solution!  Just so I understand the geometry and how the Pos sensor moves with the flap torque tube, in the pics posted in this thread are the flaps up?  IOW full retraction of the sensor's arm indicates flaps up while full extension of the arm would indicate flaps fully extended?

Todd, as I see it, the Ray Allen has a strictly linear motion, but because there are 2 pivot points (hinge and attachment to the adele clamp), as the sensor retracts, then yes the flaps are up.  Having said that you might be able to position the sensor/clamp else where and get just the opposite indications.  I think it will sort itself out with all the componets "in hand".  Hopefully someone who has already done this will confirm.

I'm doing this from memory but I think you've got it backwards. Photos show full flaps, with sensor arm fully retracted. As the flaps retract the arm moves aft as well as down. As flaps approach fully retracted, the sensor arm is moving down and not fore or aft, maximizing its motion relative to the angular rotation of the flap torque tube. Fully extended sensor arm is flaps up.
