Captain or Manager?

[b55]

Time for a new CRM topic it seems!
Is it time to change the whole current culture idea of the "Captain" into the idea of the "Flight Manager" in order to get the accident rate to move down again?
The idea of Captain and First Officer as Pilot Flying leg for leg in normal, safe flight conditions works well. But what about when it is not a safe flight condition?
There are these constant and common known areas of threats to airline flying, which are still contributing to the majority of accidents, i.e., weather, emergency and abnormal a/c mechanical problems, night flight, unfamiliar- alternate airport, congested airspace, etc. The pilots are meant to be able to sort these things out and do most of the time, but there are those times where they don't and they should have. Why is that? 6 out of 10 airline accidents the Captain was the Pilot Flying, when the accident should not have happened at all. The one person who should be managing the flight's safe progress is the one most occupied.
The concept of the Captain- Monitored Approach is a small, narrow glimpse of this idea. Is it time to greatly expand on this to include ALL the known hazardous flight situations? Whenever there is departure, enroute or arrival weather conditions, an abnormal a/c system problem, congested airspace, night flight, alternate airport, etc. the F/O will be the Pilot Flying and the Captain becomes the Flight Manager. The pilot with the most experience in the a/c type and that airline operation and, most importantly, the one with the final responsibility, is then in a better position to observe any deviations or doubts about the flight's safety. This also gives the F/O a more direct input being an active safety defence, having control of the aircraft rather than having the age old and still current problem of somehow convincing the Captain that there is a threat developing, i.e., the F/O on the KLM 747 at Tenerife, etc., etc.
Captains don't need to constantly prove that they can fly their airplane. What they do need to do is constantly manage their airplane's safety. There was a gas plant explosion a few years ago in Melbourne, Australia and the coroner's findings included that even though the workers in the control room were all trained and competent, there was no one person managing the overall situation. Logical really, isn't it? Ship captains don't steer their own ships, even at 5 knots let alone 500 kts., and space mission commanders don't steer their own space shuttles, even several hundred NM from the nearest CFIT situation. Airline Captains still fly our airliners like they did in the 1920's!!!
