Safety Requirement Details
On-line integrity A site monitoring system shall provide a monitoring using site degree of on-line integrity monitoring. A monitor warning shall be issued to ATC if the site monitor is not received or indicates a low NuC value
ADS-B Fallback Validated and published instructions procedure for reverting back to procedural control
Transition Process for Training and lesson plans to adequately ADS-B Failure cover the transition process and procedures from ADS-B control to procedural control
Project ICAO SASPOperational Use of ADS-B in Non Radar Airspace
Hazard No. 23 Corrupt data from altitude encoder
Generic Description Corrupt data from altitude encoder cause by a stuck bit . This may cause the transponder to provide incorrect alt (same as in
radar). The RAIM calculation may be affected in the KLN for cases when there is insufficient satellite causing the NUC to go below 4.
Hazard Cause/Initiating Events Loss of ADS-B positional data to the controller. Increase in workload due to transitioning period back to procedural control and reassess traffic.

Safety Requirement Details
Safety alert function - Ensure Cleared Level Adherence Monitoring is available in the CLAM ground system displays
ADS-B Fallback Validated and published instructions procedure for reverting back to procedural control
Transition Process for Training and lesson plans to adequately ADS-B Failure cover the transition process and procedures from ADS-B control to procedural control
Training to cover Training must include the process and process to request procedures for requesting alternate alternate positional positional information from the pilot when data

Hazard No. 24 Failure of connection between navigation source and Mode S transponder
Generic Description Loss of connection between the navigation source and transponder leading to no ADS B data output after 2 seconds. This is similar to loss of SSR transponder in radar.
Hazard Cause/Initiating Events Loss of ADS-B positional data to the controller. Increase in workload due to transitioning period back to procedural control and reassess traffic.
Initial Risk Residual
