The gradient from the old apron (stand 9) down past the new 3 pack to the cargo taxiway is indeed a bit steep.....but only something like 0.2 degrees steeper than the ICAO recommended limit. This effectively means that it is approved, but may have to be closed in icy conditions.
Undoubtedly the new link will improve the level of holding for the cul-de-sac once a 'one-way system' can be introduced. That should help the taxi time at peaks.
In trim.
