Melbourne Airport: Unsafe Proximity and Missed Approach Below Minimum Vector Altitude (A6-EBU)

Incident Overview and Context On the night of 5 July 2015, an operational safety event occurred at Melbourne Airport in Victoria. During the period, three aircraft came into unsafe proximity while conducting take-off and landing operations. The event involved multiple aircraft in close proximity during critical phases of flight, highlighting potential risks in air traffic management during nighttime operations. The specific aircraft types, registrations, operators, and exact locations within the airport were not provided in the source material. ## Controller Actions and Missed Approach Shortly after the unsafe proximity event, one of the aircraft was radar vectored during a missed approach. This maneuver was conducted while the aircraft was below the minimum vector altitude (MVA). The minimum vector altitude is a critical safety parameter designed to ensure adequate terrain clearance during radar vectoring. The fact that the aircraft was vectored below this altitude indicates a deviation from standard safety procedures, which may have increased the risk of controlled flight into terrain or other hazards. ## Organisational Issues and Investigation Focus The investigation into this event focused on two primary areas: the actions taken by air traffic controllers and the organisational issues identified during the process. The analysis examined how controller decisions contributed to the unsafe proximity and the subsequent missed approach below MVA. Additionally, the investigation looked at broader organisational factors that may have influenced the event, such as training, procedures, communication, or resource management. The source does not specify the exact nature of these organisational issues or the final conclusions of the investigation. ## Safety Implications The event underscores the importance of maintaining safe separation between aircraft during take-off and landing, as well as adhering to minimum vector altitude requirements during missed approaches. It highlights the need for robust air traffic management practices, particularly during nighttime operations when visual references are limited. The investigation's focus on both controller actions and organisational issues suggests a comprehensive approach to identifying and addressing potential safety risks in aviation operations.
