What to do
Air navigation service providers should raise awareness among operational personnel and ensure contingency procedures are well understood. When tracking loss occurs, controllers should notify flight crews and request selection of the alternate transponder. Operators of Boeing 787 aircraft should inform their crews about possible requests to switch transponders. All occurrences should be reported promptly according to EU Regulation 376/2014, and relevant information should be shared with EASA for ongoing monitoring.
Summary
EASA Safety Information Bulletin 2022-12 is a safety information bulletin addressing the loss of air traffic control tracking on Boeing 787 aeroplanes operating in European airspace. The bulletin highlights intermittent transponder malfunctions causing degraded radar tracking and potential loss of track display for air traffic controllers. This issue affects Boeing 787 aircraft and may impact surveillance quality and Short-Term Conflict Alert functionality.
What changed
EASA SIB 2022-12 updates the ongoing monitoring of transponder malfunctions on Boeing 787 aeroplanes in Single European Sky airspace, following a previous SIB issued in 2021. It provides updated information on the nature of the tracking loss, its operational impact, and current regulatory stance, clarifying that no mandatory airworthiness or safety directives are required at this time.
Why it matters
This bulletin matters because the loss of tracking increases workload and distraction for air traffic controllers, potentially affecting air traffic management efficiency and safety. Operators and air navigation service providers must be aware of the issue to maintain situational awareness and ensure timely responses to tracking loss events. Understanding this helps maintain safe and effective surveillance and communication between controllers and flight crews.
