AGHME sites going away, the NAT site in Strumble being unreliably in-service and the EURO site in Switzerland, Austria and Germany usually of reach… Monitoring results from these sources is problematic. Simply stated, there is still a worldwide requirement for 24mos/1000hrs RVSM monitoring.
About a year ago the big news was that if you had ADS-B, you did not need to be monitored domestically. This was only half the story. The FAA is actually monitoring the aircraft while in RVSM and ADS-B coverage. The FAA then sending out notices IF: you did not meet the RVSM standards.
Currently, past years AGHME Height monitoring results can be had at this link: https://www.faa.gov/air_traffic/separation_standards/naarmo/rvsm_approvals/
Download the Excel spreadsheet for "US IGA Operators with RVSM Approval under Part 135 or Part 91 Section 3”. From there use the search feature in Excel and look for your specific registration number. I think you will find that the latest monitoring for each aircraft was in 2019. This is the proof that will need to be kept with the B046 on the aircraft.
If ramp checked in at an international destination, (like a SAFA) you will need to prove the monitoring results along with your state approval for RVSM. LOA/OpsSpec B046 is your state approval for RVSM. Monitoring results will require a conscious next step.
To follow the regulation trail on this subject, the first place to start is your LOA for B046. My bet is that it’s going to reference AC 91-85B and 14CFR 91.703.
91.703 basically says “Do ICAO or the country you are operating in”. This drives you to ICAO Annex 6, Part 1 (Commercial) Paragraph 7.2.9 or ICAO Annex 6, Part 2 (91/GA) and then Paragraph 126.96.36.199.
Once inside EASA, AMC1 SPA.RVSM.105 will speak to the requirement to participate in regional RVSM monitoring program
The FAA’s RVSM guidance inside AC 91-85B, Paragraph 2.5 and Appendix E will go on to explain the idea of Group aircraft and the required monitoring process.
1. The answer to proof of monitoring for US Operators now, is to request an ADS-B Height Monitoring Results from the NAARMO. These are the same people that run the AGHME monitoring results. Here is link to FAA website explaining the monitoring methods and specifically ADS-B Height Monitoring: https://www.faa.gov/air_traffic/separation_standards/naarmo/monitoring_methods/
2. These results along with the B046 are what will need to be kept onboard for the SAFA inspectors.
