HC, thanks, I was quite pleased with them.
Yes P stands for Pseudo: P-ILS is the Silorsky version of what the FW world would call a 'managed' approach (LNAV/VNAV), i.e. a NPA flown coupled to the FMS, rather than a 'Selected' approach, which would be flown using ALTP and HDG etc. It works very well and it is a shame they haven't extended the use of VNAV coupling for enroute and terminal procedures too. Hopefully it will come!
