An initial RVSM height monitoring flight is due within 6 months following issuance of an aircraft’s RVSM LOA, or from the date of closing if an RVSM LOA is not requested.
When purchasing a preowned aircraft, you can check to see when the most recent height monitoring flight was completed on your aircraft via the link below. Select IGA (Excel or .pdf format) to pull up the spreadsheet, then search by N number or serial number of your aircraft.
Recurrent RVSM height monitoring is required at 2-year or 1,000 flight hour intervals, whichever is longer. It is important to record the number of hours on the aircraft on the day the flight was completed in order to show an FAA inspector the aircraft is within the 1,000 flight hour window.
RVSM HEIGHT MONITORING STATUS IS TRANSFERABLE TO A NEW OPERATOR
RVSM height monitoring status applies to aircraft, not operators; so the status transfers with the aircraft upon a sale, lease or other change of operator. If a monitoring flight was not completed, the new operator has 6 months from the date of issuance to complete an initial height monitoring flight. Otherwise, the operator continues to track hours flown since the last RVSM height monitoring flight to determine if and when a recurrent height monitoring flight is due.
METHODS OF COMPLIANCE
Aircraft equipped with qualified ADS-B out systems are now continually height-monitored during normal operations at RVSM altitudes when operating in airspace where sufficient ADS-B data is available to the FAA to determine RVSM performance
For height-monitoring service, operators beginning operations under the provisions of Part 91, appendix G, Section 9 (ADSB OUT equipped, no RVSM LOA) should notify NAARMO of their initial flight details by completing the form via the link below.
No special aircraft equipment is required to complete a GMU flight. An approved FAA subcontractor carries a GPS unit onboard the aircraft. This equipment is independent of the aircraft equipment. The aircraft must be flown at any RVSM level for 30 minutes. Turns are acceptable but flight level changes are not. The monitoring flight can be accomplished with or without passengers. The technician can meet the aircraft at a convenient location for the operator.
