On 10 October 2016, an Airbus 319 was cleared to divert to its first alternate after failing to land off its Cat II ILS approach at Porto and obliged to land at its second alternate with less than final reserve fuel after the first alternate declined acceptance due to lack of parking capacity. The Investigation concluded that adjacent ATC Unit coordination in respect of multiple diversions was inadequate and also found that the crew had failed to adequately appraise ATC of their fuel status. It also noted that the unsuccessful approach at the intended destination had violated approach ban visibility conditions.
