"Is the baro now reporting actual field elevation when coupled to the GPS?  I show 5000 feet at start up and the baro does not reset to 0 when I arm.  Yes I have foam covering the sensor with enough room for it to breath.  I am at 5000…"

"The case has foam to cover the baro. To calibrate go to the CLI (terminal in mission planner) and type 'test' 'airpressure' and it will calibrate."

"Ill have to look inside.  My case was already assembled with the board in it.   Does anyone know if the barometer needs to be calibrated or if it can be? Wade"
