This Advisory Circular (AC) describes a method to demonstrate compliance with the high consequence event protection requirements of title 14 of the Code of Federal Regulations (14 CFR) § 450.101(c) and the requirements to evaluate the potential for high consequence events in uncontrolled areas in accordance with §§ 450.1 08(b) and 450.108(c)(4). This AC provides an acceptable means to demonstrate compliance with §450.101( c)(2) and § 45 0.101(c)(3) and provides an acceptable means of compliance with conditional expected casualties requirements in § 450.108. This AC also provides guidance for an operator that chooses to propose an alternative method that produces an equivalent level of safety to the requirements in § 450.101(c)(2).
