Title: Why a Barometric Pressure Sensor?
Post by: Robski on September 23, 2015, 03:31:08 pm

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.
