AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Aerodrome operators should review and adjust runway-holding positions to comply with ILS critical area protection requirements and include relevant procedures in their aerodrome manuals. Air Navigation Services providers need to ensure their procedures mandate keeping ILS critical areas clear during approaches. National Aviation Authorities should consider these recommendations during safety oversight activities. No compliance deadlines are specified.
Summary
EASA Safety Information Bulletin No. 2015-20 is an informational document addressing the potential disruption of Instrument Landing System (ILS) signals caused by aircraft positioned within ILS critical areas at runway-holding positions. It highlights a specific incident where the Glide Path signal was disrupted during an ILS Category I approach, leading to a missed approach. The bulletin applies to National Aviation Authorities, aerodrome operators, and Air Navigation Services providers and does not target specific aircraft or engine models.
What changed
This bulletin raises awareness about the safety risks associated with runway-holding positions located within ILS critical areas and emphasizes the need to protect these areas from interference. It does not introduce mandatory safety measures or directives but recommends reviewing and updating procedures to ensure ILS critical areas remain clear during approaches.
Why it matters
The information is important for aviation professionals as it highlights a potential safety hazard that can disrupt ILS signals and affect aircraft approach operations. Ensuring that runway-holding positions do not infringe on ILS critical areas helps maintain the integrity of navigation aids and reduces the risk of missed approaches or other operational disruptions.
