We are pleased to announce the publication of ED-253 “OSED for Automation and Emergency Recovery.”
Operational Services and Environment Definition (OSED) for RPAS Automation & Emergency Recovery functions. This OSED provides a basis for assessing and establishing operational, safety, performance, and interoperability requirements for the A&ER capabilities for an Remote Piloted Aircraft Systems (RPAS) flying in non-segregated airspace. This document seeks to characterize those differentiated attributes of RPAS and define their relationship to air traffic services, other airspace participants, and operating environments of the defined airspace. This OSED captures high level requirements that have been derived and/or validated as being necessary for the automation and emergency recovery capabilities.
