I was able to map most of inputs and they are responding.
Here are a few I couldnt find the PFD mappingin Mobiflight 9.7.1.
ALT Encoder
NAV Encoder
AP button
HDG Button
VNV Button
APR Button
VS Button
FLC, Nose Up and Down - I could find this in MFD but not PFD!!
Im definitely missing something here
