Method to Determine Lift Transducer Placement
For the SCc AoA System to work properly, the Lift Transducer must be installed in the correct
location. The correct spanwise location should be at least two feet outboard of any propeller
slipstream, clear of any leading edge devices (stall strips, etc.) or internal obstructions (ribs)
and, ideally, spanwise near the flap-aileron junction.
Measuring Wing Chord Length
Once the spanwise location is determined, the wing chord length must be measured at this
position. To do this, drop plumb lines off the leading and trailing edge of the wing (flaps up) at
the selected spanwise location (x and y). Level the aircraft.
Once the aircraft has been leveled, determine the length of the chord by measuring the
distance between the two plumb lines (z).
Calculate 1.0% of this measurement. This distance (A) is shown in illustrations both above
and below. Using a combination square and level, mark this calculated length (A) on the
underside of the wing, measuring aft from the leading edge at the selected spanwise
location, as shown below. This will be the center of the cutout for the Lift Transducer Doubler.
