LDACS Update Current Status of LDACS Development and Standardization Prepared by Project Team Terrestrial Data Link (PT-T) of the ICAO Communications Panel Presented to FSMP October 2021
DLR.de Chart 2 LDACS Briefing and Overview LDACS = L-band Digital Aeronautical Communications System LDACS briefing presented to FSMP WG-11 in March 2021 (IP04) LDACS Update to FSMP WG-12
DLR.de Chart 3 LDACS Briefing and Overview Some important LDACS characteristics Well positioned in SESAR s ATM Master Plan and essential part of the Future Commun. Infrastructure (FCI) Well reflected in ICAO s Global Air Navigation Plan (GANP) Under ICAO standardization within CP/DCIWG PT-T LDACS is the first integrated CNS solution Providing high-throughput secure communications Data rates from 550 kbps 2.6 Mbps (55 260 times VDL2) Date link and digital voice communications with cyber-security included Low-latency transmission through coordinated channel access ATN/B1, ATS/B2, emerging ATS/B3 and additional future services are covered by LDACS Service priorities allow parallel transmission of high-volume AOC data while ensuring immediate access for safety-critical services Supporting navigation through an APNT service

DLR.de Chart 5 Current Status of LDACS Standardization Development of standardization documents Amendment of Annex 10 Vol III (LDACS SARPs) Draft SARPs have been endorsed by CP/DCIWG in October 2018 Final SARPs in preparation LDACS Manual (new ICAO Doc 10114) Based on SESAR LDACS specification Work in progress LDACS Validation Report Validation Document set-up Work in Progress: Collection and filling-in of validation results Amendment of Annex 10 Vol V Coordination process on L-band compatibility with ICAO Panels (NSP and SP) ongoing Delayed
DLR.de Chart 6 Current Status of LDACS Standardization Timeline for LDACS Standardization Amendment of Annex 10 Vol III and guidance material (Perf. Requirements and Tech. Specification) Delivery to CP/DCIWG for approval Q2/2022 Effective date July 2024 Applicability date November 2024 2022 2023 2024 2025 2026 Amendment of Annex 10 Vol V (Spectrum) Delivery to CP/DCIWG for approval Effective date Applicability date Q4/2023 July 2026 November 2026 2022 2023 2024 2025 2026 Timelines for amendments no longer aligned Long and intense coordination and harmonization process among ICAO Panels on L-band compatibility This highlights the need for a consistent framework for new aviation system sharing spectrum with existing aviation systems
