Hi Peter. Holy cow, time has flown since we discussed this issue last. Sorry I have been so slow to reply. Now I better understand the situation. If not in VFR using VASI there is no way the G/S for the parellel runway should be used as the only approach aid. So, excuse me. You were well within good CRM standards to challenge this approach. Again, sorry for the long delay. Cheers, Jim

Now Peter........what in the hell is wrong with you? It does not appear that the PIC was actually flying any component of the left approach here. The only nav aid was a VASI? And he wanted to use the co-located glide slope as a backup? Nothing wrong with that as long as he remained VFR and only used the G/S as reference. I don't care if you are a DPE or the administrator of the FAA. Use every tool available! That is a sign of a good pilot in my book. Where was the danger? I think you are out of line here.
