Product Code:SAE AS4970
Title:Human Factors Considerations for Outdoor Laser Operations in the Navigable Airspace
Issuing Committee:G10-Ol Operational Laser Committee
Scope:This SAE Aerospace Standard (AS) provides a method for protecting the navigable airspace around airports from unwanted laser illuminations and a procedure for proponents to seek approval from regulatory agencies for operations of various classes of laser devices and their applications within this volume of airspace. This document also provides a system of data disclosure deemed necessary for a regulatory agency to determine the potential safety effect of proposed outdoor laser activities upon flight operations within the defined airspace.
