The FAA Waiver or Authorization

EOSS often flies payloads that require a Certificate of Waiver or Authorization from the Federal Aviation Administration to remain in compliance with the rules and regulations of the FAA.

Why Read the Waiver?

The FAA issues this waiver expecting EOSS to comply with the specifications outlined by this document. All individuals involved in flight operations are expected to be aware of the provisions of the waiver and this is EXPLICITLY stated in paragraph six (6) of the "Special Provisions" section of the waiver on page two of the document.
