ADS-B Streamlines RVSM Operations

ADS-B Streamlines RVSM Operations


As part of the ADS-B Out deadline, the FAA is now in the process of streamlining RVSM (Reduced Vertical Separation Minimum) procedures and approvals for US operators equipped with ADS-B.

Although the FAA recently issued notices allowing ADS-B-equipped aircraft that meet altitude keeping equipment performance requirements to operate in US-controlled airspace without a specific RVSM authorization, RVSM operations outside of US-controlled airspace must still obtain OpSpec, MSpec, or LOA.

Aircraft with a qualified ADS-B system are now able to have height-keeping performance monitored at all RVSM altitudes where ADS-B coverage allows. All ADS-B-equipped aircraft will require RVSM monitoring every two years.

Validation is Key

Once you have the compliant ADS-B equipment, don’t forget to properly validate it with the FAA. You can do that in several ways:

  • After ADS-B installation and before the initial ADS-B RVSM flight, Notify the FAA NAARMO** (North American Approvals Registry and Monitoring Organization) using the template on its website and instructions for the flight. (
  • Fly in ADS-B airspace. After ADS-B-installation and AFTER initial ADS-B RVSM flight

Request a Public ADS-B Performance Report at the FAA website ( and follow the instructions.  

Aircraft that are not ADS-B compliant can be monitored by the following:

  • Schedule a GMU (GPS Monitoring Unit) flight. Leading Edge offers RVSM monitoring through GMU monitoring.

After ADS-B for RVSM is up and running, the FAA may reassess how many AGHME ground stations to keep operational and eventually phase out the GMU monitoring.
