Reduced Vertical Separation Minimum (RVSM)

CSSI offers a cost-effective and efficient means of completing the RVSM monitoring flight to maintain aircraft RVSM approval for operators who previously used FAAs Cleveland AGHME - The Federal Aviation Administration’s (FAAs) North American Approvals Registry and Monitoring Organization (NAARMO) recently decommissioned its ground-based monitoring system located in Cleveland, Ohio. The CLE AGHME monitored one third of air traffic operations since it was fielded. As this system is no longer available for an operator to meet their long-term monitoring requirement required to maintain RVSM approval status, operators may find using CSSI’s portable Enhanced2 GPS Monitoring Unit (E2GMU) may prove to be a far more efficient and effective means of meeting this requirement. CSSI has RVSM technicians located in both Cleveland and Pittsburgh and can provide often same day local service for completing an RVSM monitoring flight at a special low cost of $2,300.00 per flight (some restrictions apply). Contact Carol Clarke, RVSM Project Manager, at 1-866-468-8111 or email to schedule your RVSM monitoring flight.

What is RVSM?

Reduced Vertical Separation Minimum (RVSM) is defined as the reduction of vertical space between aircraft from 2,000 to 1,000 feet at flight levels from 29,000 feet up to 41,000 feet. RVSM was implemented as a means to increase airspace capacity and access to more fuel-efficient flight levels. The International Civil Aviation Organization (ICAO) and its member states first mandated the implementation of RVSM in the North Atlantic in March 1997; with other regions around the world to follow.


What is Required to Meet RVSM Approval?

RSVM has now been implemented globally and requires that aircraft operating between flight levels 290 and 410 (inclusive) be RVSM approved. Monitoring an aircraft’s height-keeping performance is an important part of the RVSM approval process. Monitoring supports the safety assessment and safety oversight function that is required with RVSM implementation. An operator must meet the minimum monitoring requirements for their aircraft as established by their respective State authority to maintain their RVSM approval status.

How Often do Aircraft Need to Be Monitored?

In May 2011, ICAO member states implemented a long-term RVSM monitoring policy requiring that aircraft operating within RVSM airspace complete a re-occurring monitoring flight in order to maintain their RVSM approval status. Operators must complete a RVSM monitoring flight every two years (or 1,000 hours of flight whichever is greater).

How Can CSSI Help? 

CSSI will play a key role in this recurrent monitoring requirement; as an approved RVSM monitoring contractor, CSSI can conduct the RVSM monitoring flight required for an aircraft to maintain its RVSM approval status. CSSI has proudly served the RVSM monitoring needs for operators since July 1999 having supported over 7,500 monitoring flights worldwide.
