The purpose of the 2015 ACI Apron Safety Handbook was to update and expand Chapter 2 of the Airside Safety Handbook (fourth edition). Aprons are the most congested and busiest areas of an airport, with complex activities that are carried out under severe space and time constraints. This handbook provides best practices for planning and designing apron layouts and facilities, as well as standard operational practices for safe apron operations, and mitigation and prevention measures for maintenance and construction activities on aprons. This resource is available from the ACI store for $125 for members and $1,000 for non-members.
