For question 5, IAN cann't do autoland ,so PFD will not display land 3 or land 2.keep A/P displaying down to 100ra then changing to NO AUOTOLAND.
If the LOC and G/S are captured, even if the original approach setup was for a VOR or RNAV approach, then AUTOLAND 3/2 WILL be displayed! Remember what the "I" stands for!
Get familiar with the FCOM. Limitations, Normal Procedures, and Autoflight are good sections to start with for IAN...
