ICAO Doc. 4444 4.6 HORIZONTAL SPEED CONTROL INSTRUCTIONS
4.6.1.1 In order to facilitate a
safe and orderly flow of traffic, aircraft may, subject to conditions specified by the appropriate authority, be instructed to adjust speed in a specified manner. Flight crews should be given adequate notice of planned speed control.
4.6.1.4
The flight crew shall inform the ATC unit concerned if at any time they are unable to comply with a speed instruction. In such cases, the controller shall apply an alternative method to achieve the desired spacing between the aircraft concerned.
UAE ATC Units are following the ICAO rules and regulations. Happy now ernestkgann? Funny that is how pilots behave according to instructions given in Europe compared to the Middle East, it must be the same as the roadmanners somehow
