The Challenge

Due to the growth in air traffic and the need to increase its airspace capacity in the Asian Pacific region, the Air navigation service provider required the development of a Safety Case enabling the implementation of reduced separation minima through the use of space-based air traffic surveillance.

What We Did

Plan Safe have been engaged to ensure the safe transition to reduced separation minima in the Indian airspace through the use of space-based ADS-B. Plan Safe provides experienced safety engineers to ensure that the new Indian airspace separation minima are compliant with applicable air traffic regulations and demonstrate that the operational risks are managed to levels that are As Low As Reasonably Practicable (ALARP).

Plan Safe activities include:

· Defining a tailored safety management approach and developing the safety argument (using Goal Structuring Notation)

· Conducting regulatory research to identify the applicable standards/regulations (ICAO, Eurocontrol, National regulations…), elaborate a detailed mapping with interactions between those regulations, index all relevant requirements into a compliance matrix and collect relevant evidence to demonstrate compliance.

· Performing hazard identification activities to demonstrate risks are managed as ALARP

· Developing the safety case providing the overarching safety argument

· Stakeholder engagement to ensure supporting evidence will be delivered on due diligence for the safety case approval.

The Outcome

The client was able to start implementing reduced separation minima through operational trials and engage with the national aviation safety regulator to obtain relevant approvals.
