''Descent in radar vectors - When under radar vectors, Dubai radar expect a minimum of vertical speed of 500’/min for all descent clearances unless otherwise stated.
Speed management - Dubai radar expect a speed reduction of approximately 10kts per NM when instructions to slow down are issued during a vector
Speed management - In Dubai, when instructions are issued to maintain a certain speed, pilots are expected to fly the exact speed issued, unlike some other ATS units which allow a certain degree of tolerance (for example: Canada ± 10kts, UK
± 5kts).''
