Excuse my latest dimness, but...
There is a development of PilotAware to add a barometric pressure sensor.
I'm just wondering why?
For altitude purposes surely GPS can provide that.
Or is this for a gross error check against GPS?
Or to sense current atmospheric pressure to compare with GPS altitude to calculate a correction to allow transmission of altitude data at 1013Mb / hPa?
Or something I haven't thought of? (The most likely situation!)
Keep up the good work. I'll build one of these little beasties once my engine is installed and the plane flying again.
