Why this is here

A25 cited it for CRM as “authority without abolishing command”: keeping avenues of challenge open while preserving decisive action. The case is CASE-127.

Corrected 2026-10-22, from the reading. Neither “authority without abolishing command” nor keeping “avenues of challenge” open while preserving “decisive action” is in the paper, and it makes no argument about command. A captain’s command is mentioned once, in third-generation training for new captains on “the leadership role that accompanies command”. The idea is better sourced from the NTSB’s recommendation on United 173 (LIT-1371), which asked for participative management for captains and assertiveness training for other crew members. What the paper does supply bears on CLAIM-422: trained capacities decay while the procedure (recurrent training) continues, and an assessed demonstration of coordination is not evidence of line practice.
