If focuse on ICAO Doc. 9859, I wonder about the ICAO statement on that SMM point 2.5.3.4:
"This example uses qualitative terms; quantitative terms could be defined to provide a more accurate assessment. This will depend on the availability of appropriate safety data and the sophistication of the organization and operation."
What kind of data source that you utilized in HIRA Apps...?
Can HIRA Apps used as Safety Data Captured and safety Promotion...?
