On 26 June 2017, an Airbus A319 which had just taken off from Stuttgart came into conflict in Class ‘D’ airspace with a VFR light aircraft crossing its track and when, at 1,200 feet agl, the TCAS RA to descend which resulted was followed, an EGPWS Mode 3 Alert was generated. Clear of Conflict was annunciated after 10 seconds and climb resumed. The Investigation concluded that the light aircraft pilot had failed to follow the clearance which had been accepted and had caused the flight path conflict which was resolved by the response of the A319 to the TCAS RA.
