Another thought and harking back to an approach and runway previously very familiar to me. Imagine being told that the glideslope is U/S and this will be a LLZ/DME approach to LGW 26L. Old plate Cat B, C and D limit 700' 1200ms, new plate 700' 1500ms. Which do you apply and what is the ATC approach ban limit ,prior to a possible MOR?
And I agree with the comment re the hold entry deliniation, many flights can be single pilot/IFR and we need all the help available.
