Summary grant process will speed up Section 333 exemption approvals for many commercial unmanned aircraft system operators. Section 333 is part of 2012 FAA reauthorization law that lets Secretary of Transportation determine if certain low-risk UAS operations can be authorized prior to finalizing small UAS proposed rule. Although FAA still reviews each Section 333 petition individually, agency can issue summary grant when it finds it has already granted previous exemption similar to new request.
