Guys,
I have a Ray Allen POS-12 Position Sensor installed to provide flap position indication. It's working great.

How can I configure the display such that at HALF FLAPs the display bar shades only half way down? Right now it's showing just under ¾ of the bar shaded.

I see an option on the General Setup / Flaps & Trim Calibration (Page 1) as "MARKED AREA (in percent"). Is that what I should use? If not, what's that used for then?

Thanks,
Howard (GlaStar)

There isn't a separate calibration point for half flaps in the current software. You could manually adjust the voltage in the Flaps Down box to make half flaps look better, but that would mean full flaps wouldn't fill the indicator.

The MARKED AREA is for Aileron and Elevator trim. It adds a band to the indicator covering that area.
