Just hooked up a new G3X Touch system, airspeed indicator is showing airspeed (72 knots) in the hangar. Does anyone know if there is a setting to zero that out? Or what needs to be done to set the airspeed indication up.

There is no adjustment on the airspeed. Have you tried unplugging the pitot/static tubes from the GSU25 to verify you don't have a line plugged?

In a similar vein..... A big low passing Illinois right now. Taped over static ports would show that with rising pressure. (Been there done that... )

have lines off of the gsu 25, so no possible pressure. Weird!!!

Also have a back up round gauge in the same system and it shows 0

Hello John,

You say above that "all the lines are off", but please make sure the fittings are removed as well (if not already). It is surprising how often we have heard from customers who installed fittings that were blocked which resulted in a pressurized pitot or static port.

Please also install the V4.10 software, and if the problem persists, contact us by phone or email as shown below and we will get you fixed up.

Thanks,
Steve
