Safety Requirement Details
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
Adequate RMA Ensure adequate RMA (reliability, maintainability, availability) requirement is requirements for specified for the communications systems comms system (e.g. links, PSN, modems,etc) between the ground station and the ATM centre. Need to provide an alternate path if the third party link service provider cannot meet RMA requirements.
ADS-B Fallback Validated and published instructions procedure for reverting back to procedural control
Monitoring of Comms Ensure monitoring is provided for all equipment communications equipment used in ADS B

Hazard No. 29 Unstable sensitivity of ground sensor
Generic Description
Unstable sensitivity of the ground sensor will cause tracks dropping in and out of coverage in the control area.
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 Occasional Remote
Consequence Cat 3 Cat 3
Risk C D

Hazard No. 30 Failure of Site Monitor
Generic Description Site Monitor failure will render the ADS B data not acceptable for separation however could still be used for situation awareness
Hazard Cause/Initiating Events Indicate the potential loss of ADS B data
Initial Risk Residual
Risk
Likelihood Occasional Occasional
Consequence Cat 3 Cat 4
Risk C D
Existing Mitigation Controller observes tracks with respect to reference data (e.g. maps, radar returns, etc)
Safety Requirement Details
Coverage of Site Ensure ATC training and procedures cover Monitor failure in ATC the the scenario of Site Monitor failure training
Warning for Site Ensure a warning is sent to ATC when the Monitor failure ADS B site monitor is faulty or unavailable.
