Instant and accurate information Instant cooperation Instant action Global
Maritime example: GMDSS: Global Maritime Distress and Safety System; LRIT: Long Range Identification and Tracking
Different levels of Information sharing
Need for a consistent “overlay”

Know where aircraft fly
Know when aircraft are in distress
Enhance ability to rescue
Enhance ability to recover

“A process, established by the operator that maintains and
updates at standardised intervals a ground based record of the
four dimensional position of individual aircraft in flight”

Performance-based Standards and recommended practices for normal flight tracking
No change to ATC procedures i.e. no change to SAR alerting
Establish operator responsibility to track aircraft
Not technology-specific – using existing technology
State/organisations feedback e.g.: Area of applicability/responsibility
Applicability date
Information sharing/security
Reporting rate
Timelines • January 2015
– Preliminary review by ICAO ANC
• March 2015 – State Letter
• September 2015 – Review of
feedback
– Updated SARPs
• November 2018 – Applicable

Operator to track flight from Take-off to landing Exception when fully under ATS surveillance Automatic event detection
Update rate: 15 min < jan. 2021 3 min > jan. 2021 (without automated means for a/c accident localisation)

Performance-based Standards and recommended practices for distress flight tracking
Not technology-specific Location of an accident site within 6 NM Activated
Automatically based on flight behavior Manually from the air Manually from the ground
Power and position information autonomous from other a/c systems Applies to new aircraft from 2021 Incentive for early adoption as an alternative to second ELT
