Ever wonder how the FAA came up with 91.211 requiring oxygen use above 12,500 feet MSL for more than 30 minutes and any time over 14,000 feet MSL? The answer is geography, not physiology. When these rules were written, oxygen systems were expensive and heavy. General aviation wanted to fly anywhere in the U.S. without oxygen, and you can fly any mountain pass in the 48 contiguous U.S. states in less than 30 minutes between 12,500 feet and 14,000 feet MSL.

The FAA has released the medical requirements for the Pilots Bill of Rights 2 (PBOR2) and quite frankly, I think it is a home run for general aviation, pilots, and the AOPA who fostered it through Congress. The new program is called BasicMed that is technically the FAAs implementation of medical requirements in the PBOR2 portion of the FAA Extension, Safety, and Security Act of 2016 known (of course) as FESSA. The final rule from the FAA, released January 10, 2017, and effective May 1, 2017, can be found on the FAA web site, FAA.gov.
