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.
  Initial Risk  Residual

Existing Mitigation 

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

  Likelihood  Remote  Remote 
  Consequence  Cat 3  Cat 4 
  Risk  D  D 
Existing Mitigation Only licensed installer is allow to install the avionics equipment in the aircraft.

Hazard No. 25 Data Corruption
Generic Description Data corruption causing erroneous data to the transponder leading to incorrect data transmitted. This is a transitory error and
