The aircraft transponder has two knobs instead of four. These have been mapped to the first and last knobs on the panel. This can easily be altered if desired.
VOR/NAV/ILS
As on the real aircraft, the VOR/NAV/ILS switches should be switched to VOR in order to activate that function.
MON
MON cannot be set - aircraft issue.
VHF Frequency Transfer
Transfer of some VHF frequencies in the 136 range is slightly buggy - aircraft issue.
