There certainly seems to be some disconnect here because the following is from the briefing document provided to EK crews regarding the new procedures. If the procedures are not applied with the flexibility to shortcut aircraft to improve efficiency then the whole point is lost.
On first contact Dubai Approach they will advise “Expect to turn base at”. Once established downwind if ATC decide that they are unable to turn at planned fix then ATC will provide radar vectors.
Pilots can expect to fly the trombone when traffic levels in the CTA are elevated however if there is reduced traffic during quiet periods ATC may offer a track shortening
DESDI direct RULAM direct DB414 for 12L/R or,
BUBIN / GIRMI direct LOVAL for 30L/R
If ATC want to shortcut a flight they will notify the crews with associated track miles. For example:
i.e. “Emirates123, direct LOVOL available, 55 track miles to touchdown if able.”
