On 7 October 2017, an arriving Boeing 787-9 and a departing Boeing 777-300 lost separation during intended use of runway 29 at Delhi when the 787-9 commenced a go around from overhead the runway because the departing 777-300 was still on the runway and came within 0.2 nm laterally and 200 feet vertically after ATC had failed to ensure that separation appropriate to mixed mode use was applied using speed control. The conflict was attributed to failure of the TWR controller to adhere to prevailing standard operating procedures.
