Ground Risk Class Determination for SORA

In plain language

When calculating the ground risk class for a SORA, you must evaluate the entire area of your flight geography, contingency volume, and ground risk buffer. The highest risk class found within this combined area must be used.

Requirement as structured

To determine the ground risk class for a SORA, the operator must consider the area of flight geography and contingency volume projected onto the ground as well as the area of the ground risk buffer, assuming the highest ground risk class occurring in the entire area.

Original regulatory text

To determine the ground risk class, the area of flight geography and contingency volume projected onto the ground and the area of the ground risk buffer must be considered. The highest ground risk class occurring in the entire area is assumed for the SORA.
