Which term denotes the airspace concept where reduced vertical separation is implemented between FL290 and FL410?

• A. RVSM
• B. SUA
• C. High Altitude Sectors
• D. LOA

Answer: (A)

Reduced Vertical Separation Minimum, RVSM, is the airspace concept that allows aircraft to be separated by 1,000 feet vertically between FL290 and FL410, instead of the traditional 2,000 feet. This system increases capacity and efficiency in the en-route environment by requiring precise altitude maintenance and reliable altitude reporting. To meet RVSM standards, aircraft must have two independent altitude measurement systems, an automatic altitude-keeping capability, and a certified altitude-encoding transponder, with ongoing verification that performance stays within specified limits. Outside RVSM airspace, standard vertical separation applies. Other terms refer to different concepts: Special Use Airspace blocks certain activities for safety or security; High Altitude Sectors describe how airspace is organized for traffic flow at high levels but not the separation minimum itself; a Letter of Agreement outlines procedural commitments between organizations.
