This means that you updated the .sfg engine sensor definitions on one display but not the other. It does need to be loaded onto each display individually. The latest version of the file is available
here. I'd suggest the following steps.
- First, download the latest version of the .sfg file from the above link and copy if to a USB stick. Currently this file is called sensor_08_11_2014.sfg (this is what you will see on the stick.
- Next, from each display, grab the existing engine sensor definitions on each display by plugging the USB stick into that display and selecting SETUP MENU > SYSTEM SOFTWARE > EXPORT SETTINGS. Give each display's file a unique name ("Left" and "Right" for example).
- Finally, on each display, load the latest sensor definitions by plugging in the USB stick and going to SETUP MENU > SYSTEM SOFTWARE > LOAD FILES, and then select sensor_08_11_2014.sfg and press LOAD.
I'm not sure I understand your second question. But the Zero Pressure Airspeed Calibration is only used to adjust the airspeed indication to make it more accurate at very low airspeeds.
