EASA SIB 2015-25: Publication of declared distances for runways where intersection take-offs take place

What to do

Aerodrome operators should review and update their AIP entries to ensure declared distances for all authorized intersection take-off points are complete and accurate, install appropriate intersection take-off signage, and update aerodrome manuals accordingly. Competent authorities should incorporate these recommendations into their oversight activities and ensure operators are informed. No specific compliance deadlines are stated, but timely action is advised.

Summary

EASA Safety Information Bulletin 2015-25 is a regulatory communication addressing the publication of declared distances for runways where intersection take-offs are authorized. It applies to European aerodrome competent authorities and operators, emphasizing the need to publish accurate declared distances in the Aeronautical Information Publication (AIP) to support flight crew performance calculations. The bulletin does not target specific aircraft or engine types but focuses on aerodrome operational data.

What changed

EASA SIB 2015-25 highlights that some European aerodrome operators have not published the required declared distances for intersection take-offs in their AIPs. It clarifies regulatory requirements under Commission Regulation (EU) 139/2014 and related guidance material, reinforcing the obligation to provide complete and up-to-date declared distances and to install intersection take-off signs where applicable. The bulletin introduces recommendations to improve the accuracy and availability of this critical aerodrome data.

Why it matters

Accurate publication of declared distances for intersection take-offs is essential for flight crews to perform correct take-off performance calculations, directly impacting flight safety. Aerodrome operators and competent authorities must ensure compliance to avoid operational risks and support safe aircraft departures. This information also aids in regulatory oversight and aerodrome certification processes under EU regulations.
