Fuel flow and AOA

Hello. Looking forward to receive Skyview. I already got FuelFlow transducer and it's wired to Brauniger EFIS/EMS. It shows fuel cosumption and quanity of fuel left in tanks. I just have to input quantity/amount of liter/gallons, when I am filling the fueltank. The rest is math in computer. Does SkyView compute quantity of fuel or just shows actual usage?
Was thinking of installing AOA pitot probe. How to calibrate it? I have read installation manual, but still dont understand it. Angle is different if I use +15, 0, -15, -30 or -45 deg. og flaps. In different weather conditions, I am using different landing flaps configuration.

Tanks :)

The fuel flow transducer, when hooked to SkyView, will show usage,flow, remaining, and more based on your initial input and the flow, basically like what you have now. The direct quantity sensors, on the other hand, measure fuel directly and work completely independently from that.

The AOA calibration does not differentiate (know about) different flaps settings, but when you do a series of stalls in different configurations it makes sure that all of them result in a stall warning. For some wings, this can mean that you may want to leave out thos flaps configurations that you don't do approaches in to get the best-performing AOA indicator without any nuisance alarms.

Any progress on improving this functionality?

I think all you need for about a %1000 improvement would be to take a contact input from a switch for flap position (up or down) and use that to select from one of two calibrated settings for AOA.

It seems like the current method is not very good...either it's valid in the cruise configuration, which is fine as I don't want to inadvertantly stall, but completely useless for landing, or useful for landing but a distraction and waste of screen space the rest of the time.

Come on...this is a simple thing to fix...

Nothing in the immediate pipeline here, but I've made sure it will come up for discussion as we continue to rank features that we want to add for implementation.

Thanks. I'm actually really surprised this isn't already in there, as it seems to be a safety of flight issue. G-meters are nice and all, but knowing your (correct) angle of attack under different configurations is more important.
