There's nothing wrong with intercepting the GS from above- I did it only today! I don't understand the enormous horror it has for some people. It's something we are going to have to get more used to with CDAs and noise-saving approaches. Once you are cleared for the ILS, all that then matters is you capture the GS before you reach the MCP selected altitude, so be sure to wind it right out of the way or you will find yourself level in seconds and unable to continue the approach. So if you then forget to reset the MCP altitude to GA altitude, and then GA, you will capture that selected altitude, so you must remember to set proper GA altitude after you have captured the GS. There are other complications, for instance, whatever speed you are doing at altitude capture will become then become the captured speed at that altitude. So one must stay well on top of the automatics or disengage them totally (not recommended!). Clear?
