From the article:

“IATA’s working paper calls for the global standards-setting body to support raising the upper age limit for pilots to age 67, provided a second pilot is younger than 65. IATA does not propose any new data-driven reviews to support the move, but advocates “a system of standardized data collection about the medical status and health-related performance across all pilot age groups,” the recently submitted paper said. The data should “at a minimum” include medical conditions, medical reasons for retirement or loss of certificates, “and inflight safety and performance data [for all events],” it added.”

Questions:
Why would the 2nd pilot need to be younger if there’s no degradation in safety???
Why not study it(and collect data first), then make a proposal?
This is the CRM equivalent of committing to an alternate without asking Dispatch and your First Officer… aka poor planning and decision making. This group appears to lack the safety oriented thinking required to make such decisions.
