On 22 April 2012, an Airbus A320 and a Boeing 737 came into close proximity near Dubai whilst on the same ATC frequency and correctly following their ATC clearances shortly after they had departed at night from Sharjah and Dubai respectively. The Investigation found that correct response by both aircraft to coordinated TCAS RAs eliminated any risk of collision. The fact that the controller involved had only just taken over the radar position involved and was only working the two aircraft in conflict was noted, as was the absence of STCA at the unit due to set up difficulties.
