sNMAC-Initial
This MATLAB code supported, "A Quantitatively Derived NMAC Analog for Smaller Unmanned Aircraft Systems Based on Unmitigated Collision Risk." It provides an initial quantitative assessment of sNMAC candidates. A final and adopted sNMAC definition should be informed by stakeholder needs, such as those of the FAA and standards developing organizations.
NMAC = near midair collision
sNMAC = small-craft near midair collision
