My first officer said that we can establish the G/S and shoot the approach, but I think maybe we'd better us vertical speed to descent and maintain the G/S until we passing the IF. He give me the reasons like that we under the Radar and higher then every minimums, I agree with these but I still think that is not comfortable for me.
I am happy with that part. Personally I like to find the G/S far out and just follow it down as reference for a continuous descent. I do of course confirm that the G/S doesn't take me below any "hard altitude", issued descent clearance, step-down altitude etc. The G/S is normally only protected to a certain distance, 10 nm in US. For the most part you can pick it up earlier than that. And once again, as long as I don't bust any altitude limits it's a good reference.
