JimL, just a few more points with your post
If this so called committee were so experienced and you seem to think that the procedures they prodcued work......why so many CFIT(W) over the past decade.
If you really read the posts on this forum properly you would see that your ill defined flight path at 3 degrees from 3/4 Nm "may require a period of level flight" (from where-to where) is the whole, the entire and the complete point of the argument.
Taken in its most simple form, surely even you must agree that the higher you are above the deck, the earlier the fully formed sight picture will appear and the more time you have to shed speed (from IR stable) with minimum pitch up attutude to reduce speed in the final stages, leading to a more stable the approach.
Allied to this principle is the requirement to produce definitive intervention policies for when the approach is going wrong. This can only be done by clearly defining the approach parameters from the outset.
Before you launch into another lecture about what we already know remember we are talking about Night VMC (Hate that phrase) and not an ARA. 8/8 black if you like.
