Which acronym refers to an official agreement between facilities?

• A. FSOP
• B. ERAM
• C. LOA
• D. RVSM

Answer: (C)

An official agreement between facilities is represented by a Letter of Agreement. This document formalizes how two or more ATC facilities will work together, outlining who is responsible for a given airspace or route, where transfers of control occur, and the exact coordination and communication procedures to use. It ensures consistent handling of aircraft as they move between facilities, covering handoffs, data sharing, and contingency steps so operations remain smooth across boundaries. This differs from a Facility Standard Operating Procedure, which guides a single facility’s internal processes, from RVSM, which is a vertical separation standard, and from ERAM, which is an automation system used to manage en route traffic.
