misd-agin:
Company provides Jepps 10-1R page. Provides min vectoring altitude information. Nice to have in mountainous terrain.
Jeppesen provides the 10-1R to all subscribers but only when the ICAO member state publishes the MVA data in the AIP.
Countries such as the U.S. and Canada do not provide source MVA data, thus no 10-1R pages for those countries (and others as well).
