What CRM was really brought in for was to make fullest use of all the resources in the cockpit.
One of my upstream colleagues in Houston has sent me this:
Alter cockpit leadership style, NTSB urges in Lubbock crash report | Lubbock Online | Lubbock Avalanche-Journal
The NTSB recommends to the Federal Aviation Administration that pilots and first officers undergo simulator or role-playing exercises “that teach first officers to assertively voice their concerns, and that teach captains to develop a leadership style that supports first officer assertiveness.”
The report summary notes the first officer recognized the problem and asked the captain if they should perform a go-around, which was the correct move.
It says her failure to press the issue “likely resulted from the steep authority gradient in the cockpit, and the first officer’s minimal training on assertiveness; further the captain’s quick dismissal of the first officer’s go-around inquiry likely discouraged the first officer from voicing her continued opinions and challenging the captain’s decision to continue the unstabilized approach.”
The report also was critical that the captain’s preoccupation with resolving the problem with the flaps kept him from calling out the airspeed changes to the first officer, who was flying the plane.
This NTSB's findings on this accident, that no one else on PPRuNe seems to have bothered posting about shows that CRM is still not being routinely applied. See the video here:
